Slope Stability Analysis
Sirovision’s Slope Stability Analysis tools offers a much more sophisticated, less conservative stability classification of potential hazards in comparison to traditional methods based only on orientations of mapped structures. The consideration of rock characteristics such as rock density, cohesion, friction and persistence of structures in conjunction with pore pressure grids, geological domains and imported complex structures produces a more reliable computation of slope stability.
The advantage of 3D surfaces means detected hazards can also be visualised and and measured accurately for maximum benefit to geotechnical and mining engineers.
Added value to your operation
- Engineering staff can identify the physical size, location and stability classification of features in your pit walls (i.e. you will know where failures are most likely, as well as the volume of materials involved)
- Engineered solutions to minimise risk and maximise safety in the operations can be implemented to ameliorate problems
- It enables monitoring equipment to be correctly placed to further improve safety in the pit.
Solutions provided by Sirovision’s slope stability data
- Geotechnical Engineers use stability data to design and maximise ground support efficiency with confidence that the efforts are focused in the correct areas and that safety and risk are paramount considerations.
- Mining Engineers use stability data to design bench widths and pit wall angles to maximise ore extraction and productivity with a clear understanding of the safety aspects and risks associated with the wall stability.
Slope Stability Analysis functions include:
Plane Intersection Tool
The Plane Intersection Tool provides the practitioner with a ‘feel’ for the surface being mapped by allowing them to examine potential blocks that may form in advance of the slope stability analysis. This should assist experienced practitioners to better map the surface.
Automated Wedge Detection
The tetrahedral wedge detection tool allows the practitioner to analyse the ‘wedges’ formed between two orientation discontinuity sets. It includes the determination of a release surface to construct wedges whose mass and volume are determined from the characteristics of the rock surface (e.g. bedding). The practitioner has control over the analysis parameters that include the limiting equilibrium stability calculations.
Automated Block Detection
The polyhedral block detection tool allows the practitioner to analyse rigid blocks daylighting on the rock mass surface. Unlike the Wedge Analysis method, blocks of any shape (called polyhedra) can be accommodated (i.e. not just simple wedges) and their mass and volume are determined from the characteristics of the rock surface domain. The practitioner has control over the analysis parameters that include the limiting equilibrium stability calculations.
Importable geotechnical data
The following objects are considered when calculating the factor of safety of detected wedges and blocks offering a more sophisticated and realistic determination of slope stability.
Geological domains can be imported or mapped manually on 3D surfaces. Rock density, cohesion, critical friction and pore pressure values can be attributed to each domain.
Pore Pressure Grids
Pore pressure grids can be imported as ASCII text files. Pore pressure values in KPa are colour coded to show gradients in pressure.
Curved or complex structures can be imported as .DXF. Automated block detection analysis can take into account curved or complex structures and detect the blocks that form based on the intersections of the mapped planar and imported structures.


SIMEC Energy Australia (previously SIMEC ZEN Energy) and SIMEC Mining, both members of Sanjeev Gupta’s global GFG Alliance, have today welcomed the shortlisting of their innovative Middleback Ranges Pumped Hydro Generation Project for the next round of the Government’s Underwriting New Generation Investments Program (UNGI).
The 220 MW Middleback Ranges Pumped Hydro Generation Project is a unique project that has been developed by both SIMEC Energy Australia and SIMEC Mining to optimise the overall economic value of its development and operation to industry, the community and the Upper Spencer Gulf region.
SIMEC Energy Australia and SIMEC Mining identified the Project in their UNGI submission as it provides the potential to underpin electricity supply to its commercial and industrial customers at globally competitive prices. In addition, delivery of this new sustainable energy generation asset will contribute to emissions reductions, sustainability objectives, and increase the overall reliability and security of electricity supply in the region.
SIMEC Energy Australia has a strong Board and management team including Chairman Sanjeev Gupta and internationally renowned economics professor, Ross Garnaut.
Speaking on the shortlisting, Mr Gupta said “The Commonwealth Government’s interest in this generation project is welcome. Funding support from the Commonwealth via the Underwriting New Generation Investments program will underpin, and hasten, the sectoral transformation currently underway. GFG works hard to promote change and sustainability and this project looks to evolve a primary use from mining to creating sustainable clean green power generation.”
SIMEC Energy Australia CEO, Marc Barrington, said “I am very pleased that the Commonwealth Government has positively responded to our Middleback proposal by placing it into the next round. For businesses such as ours, funding support will accelerate investment in new generation capacity, allowing us to ultimately supply customers in the region with cheaper electricity than currently available.”
The project is located on the SIMEC Mining owned and operated 10 Mtpa iron ore mine site in the Middleback Ranges, approximately 60 kilometres from the town of Whyalla. The project will see a successful upcycling of a former mining operation to form an energy storage and generation site.
SIMEC Mining Executive Managing Director, Matt Reed, said “The project will be a first of a kind Australian project, integrating mining with pumped hydro which will benefit from reduced civil costs and use mining overburden to create the dam walls. With the prefeasibility study complete we are looking forward to working with Government to demonstrate the full life-cycle value of the mine, working with SIMEC Energy Australia to deliver low energy costs to industry.”
SIMEC Energy Australia has already been highly successful in delivering new, innovative and globally competitive energy solutions in South Australia, with contracts signed with a number of large energy users in the region and being the sole electricity retailer for the South Australian Government. The company has also recently announced its growing presence in the Victorian electricity market in an assertive move to shake up the market and deliver intelligent solutions for large Victorian energy users.

Gold developer West African Resources (WAF), listed on the ASX and TSX-V, has made a key management appointment as it moves into the development phase for its 90-% owned Sanbrado gold project in Burkina Faso. Sanbrado will be mined by both open-pit and underground methods.
Matthew Wilcox will join the West African executive team as Chief Development Officer in September and will directly manage the construction of Sanbrado. He is highly experienced in the gold mining construction industry in West Africa, having spent the past eight years working for Nord Gold SE, which operates nine gold mines globally, including three mines in Burkina Faso and one mine in Guinea.
Wilcox was Project Director for the construction of Nord Gold’s 4 Mt/a Bissa gold project and 8 Mt/a Bouly gold project, both located in Burkina Faso. He was General Manager of the 6 Mt/a LEFA gold project in Guinea and, most recently, was Project Director for the construction of the 12 Mt/a Gross gold project in Siberia, Russia.
He has also worked with engineering firms Lycopodium and Minproc based in Perth. He holds Bachelor of Science (Applied Chemistry) and Bachelor of Engineering (Chemical) degrees from Curtin University, Perth.
WAF recently announced the results of its updated Feasibility Study (FS) for Sanbrado. The study envisages an initial 11-year mine life, including 4,5 years of underground mining, and showed a 76 % increase in probable reserves to 1,6 Moz (20,4 Mt at 2,4 g/t gold). The project will have average annual production over the first five years of mine life of 211 000 ounces gold and a 16-month post-tax pay back on US$185 million pre-production capital costs.
Optimisation of the FS process plant is underway following completion of the updated FS in June. The company has identified that by increasing the size and power of both the SAG and ball mills to 4 MW each from 3 MW and 3,2 MW respectively, the throughput rate while feeding higher grade fresh (hard) ore can be increased to maintain a minimum feed rate of 2,0 Mt/a, up from the 1,6 Mt/a detailed in the FS.
The benefit is a reduced mine life from 11 years to approximately eight years and a reduction in capital spares requirements by utilising common spares. A substantial improvement in project economics is expected by reducing the FS mine schedule without a material change in capital requirements. Optimisation of the plant design is ongoing and will continue during detailed design which is expected to be completed by Q1 2019.
Early construction works have commenced at Sanbrado. The 150 000 m3 water storage pit located in the stage 2 M5 open pit has been completed and is filling up with surface water runoff from the current wet season. The location of the underground portal has been confirmed and WAF expects to break ground on the underground portal in October following the wet season. Final site selection for the Stage 1 construction camp has also been confirmed. Converted sea containers are being completed in Ouagadougou by a local contractor and their installation on site will commence in October.
WAF has completed all major permitting milestones relating to Sanbrado and says it has received strong interest from international resource banks, debt funds and royalty companies to fund the majority of the project’s capital requirements. The company will review the finance proposals during Q3 2018 and intends to appoint a funding syndicate in Q4 2018.


Rare Earth Metals Assessment and Supply Chain Actions
Statement of Work and Project Statement
The primary purpose of this project is to gather information related to the probability of a shortage of Rare Earth Metals occurring in the very near future, pinpoint when demand will exceed supply, and identify key driving factors. The project is also intended to drive actions that will increase supply and examine the feasibility of reclamation/recycling efforts. Development of alternative materials will also be investigated. These project activities are designed to prevent companies from becoming victims of the volatile REM supply and highlight any reductions which would lead to supply chain and market disruptions.
Additionally, the project will raise awareness of the severity and potential impact of REM supply issues with appropriate governmental agencies and industry trade groups.
There are 5 project tasks that will be addressed by the project team. Details describing each of the tasks listed below can be found in the Statement of Work. All iNEMI members are encouraged to review the SOW and Project Statement and sign-up for this important project.
The ultimate goals of the project are to assist in the re-establishment of a viable REM industry in the U.S., to develop skills, and to rebuild and restructure the REM supply chain and infrastructure.

“Justin has proven his worth by being more than an investment advisor. He tries to bring value to every interaction and is a name to watch in this industry going forward.” - Fabiana Lara, creator of The Next Big Rush
"Justin Hayek has been my investment advisor for over 7 years. I find his market knowledge invaluable. He has helped my portfolio grow, exceeding my expectations. I will continue to take advantage of his expertise and would highly recommend him to anyone looking for a fantastic advisor!" - Chase Shymkiw, Maple Ridge, BC
In Pursuit of the Next High-Grade Silver DiscoverySubmitted by Justin Hayek on October 9th, 2019
Over the last six years, the mining sector has had glimmers of hope. There have been too few successes to cheer about, although there have been a couple darlings in the space. One in particular that stands out is SilverCrest Metals (TSX:SIL).
SilverCrest Metals' (TSX: SIL) 4 year Stock Performance
SilverCrest’s stock has been a shining star in an otherwise dim universe. The company’s flagship asset is the Las Chispas Silver-Gold project in Sonora, Mexico. What I believe sets Las Chispas apart from its peers and ultimately has delivered a lot of value to its shareholders is the following:
- Las Chipas was never drill tested despite being a past-producing silver-gold mine, therefore coming to the market as a brand new ‘discovery’ and the market reacting as such
- Well-endowed mineralized system; hosting 36 known vein structures generating significant upside potential post-discovery
- Potential to host economic, high grade silver-gold deposit as outlined in its PEA
These ‘value add’ points checked a lot of boxes for the investing community, which is what led to SilverCrest’s incredible success. I believe the market will continue to reward silver/gold explorers and developers that meet the above criteria.
One junior miner that meets these criteria is Vizsla Resources Corp. (TSXV:VZLA), a mineral exploration company focused on a highly prospective silver-gold property in Mexico, the world’s top silver-producing country (corporate website: https://vizslaresources.com).
Vizsla recently acquired an option over a high-grade silver and gold land package in Panuco, Sinaloa, Mexico’s prolific precious metals district. Panuco has been producing silver and gold from high-grade veins for more than 450 years and boasts over 75 kilometres of cumulative vein strike length. The region’s first silver production took place back in the 1500’s and has been producing intermittently ever since, with steady production taking place over the last several decades.
"Panuco is one of the best opportunities I've seen in my career. We have an option over one of the largest, most important historic mining districts in Mexico – consolidated for the first time ever in its history,” - Vizsla Resources Chairman Craig Parry.
Upon exercise of the option agreement Vizsla will own two producing silver-gold mines, a mill, over 35 km of known underground workings, multiple tailings facilities, a significant road network, power and associated permits.
Up until now, this major high-grade silver-gold vien system, consisting of 20 known viens with over 75 km of cumulative strike length, has been largely unexplored outside of a small 2018 drill campaign that revealed an intercept containing 2,235 g/t silver and 9.5 g/t gold over a 4.23 metres (Hole SCC-07-09 Capstone).
This is also the very first time Panuco will be explored as a consolidated region, creating a project that totals 10,542 hectares and is comparable in size and geology to SilverCrest's Las Chispas project as well as First Majestic's San Dimas mine. Vizsla Resources hit the ground running at Panuco, beginning systematic exploration immediately following the announcement. The company expects to be drilling within three months and to complete a maiden resource in 2020.
If this company interests you, you’ll definitely want to keep an eye out for constant news flow in the months to come regarding its progress at this prolific silver-gold project. (Vizsla's corporate presentation here)
As with any mining exploration company, there is a high degree of risk involved. Please consult with your investment advisor before investing to ensure suitability and risk tolerances have been considered before you invest.

In line with the development trend of the market, we must continue to improve the performance of pneumatic conveying pump equipment to follow the changes in the market, so that the equipment can create higher efficiency under the condition of low energy consumption, and more in line with the needs of customers.
Fucheng Machinery has been researching lift pumps for many years. It has the effect of achieving ideal conveying capacity for various powder materials. During the construction of the lift pump, it is necessary to pay attention to the placement of various components. Only in this way can the lift pump be able to Maintains smooth material transportation during normal work, so as to achieve a good transportation effect.
The characteristics of the lifting pump are that it has a good conveying effect for powder materials, and meets many requirements of strict industrial environmental protection. Due to the simple operation and structure of the lifting pump equipment, the amount of operation is small, and it can continuously send ash, it can automatically adjust The output of the lifting pump can well achieve the effect of ash delivery, the pressure of the ash delivery medium is low, and the equipment pipeline valves should not be worn. Therefore, the investment of personnel and the low-cost maintenance of the equipment in the later stage are effectively controlled. Compared with other powder conveying equipment, it is much lower, and there is basically no maintenance amount in the later stage of operation.
Fucheng mechanical engineers need a certain level of material for the construction between the lift pump and the lower bin. When the amount of material collected by the electric dust collection increases in a short time and the lift pump is still working normally, the height of the material level naturally rises. Increasing the height of the material level increases the potential pressure and the corresponding increase in the amount of conveyance until the system automatically balances. When the material is in this state, the powder material can enter the silo to reach the ideal conveying state. When the amount of material is reduced and the lift pump is still working normally, the height of the material level naturally decreases. With the decrease of the material level, the potential of the material decreases and the conveying volume is reduced accordingly until the system automatically balances.

Poland: Ministry of Energy prepares for three scenarios in the mining sector
The Polish Ministry of Energy is preparing for three scenarios predicting the development of the country’s mining industry in 2016 to 2030: optimistic, realistic and pessimistic. The new strategy is to enter into force in May of this year. This document is also a sign that Poland is still planning to base its energy policy on coal. Apart from this, it shows that the government has backed away from its intention to build nuclear power plants.
The optimistic scenario assumes that demand for coal may rise to up to 86.1 million tonnes (about 20 per cent). The condition for realising this scenario is to build a 1000 MW coal-fired power plant in Ostrołęka and to construct at least two installations for coal gasification. In a realistic scenario, demand for coal will be maintained at today’s level and one installation for above-ground gasification of already excavated coal using about 1 million tonnes of coal per year is to be built in 2020 (most likely in Kędzierzyn).
If the pessimistic scenario takes place, the demand for coal will decrease to 56.5 million tonnes. The reasons for this phenomenon may be lower permitted emissions of gas from boilers and the development of alternative technologies for producing electricity. This option assumes that there will be no significant government intervention in the energy sector.
Moreover, the Polish government is planning to establish an Upper Silesian Division of Energy Coal (Górnośląska Dywizja Węgla Energetycznego). It is planned that the Division will consist of the associated Polish Mining Group (Polska Grupa Górnicza) and Katowice Coal Holding (Katowicki Holding Węglowy) together with Węglokoks Kraj (which owns the well-known Bobrek coal mine). The plan should be ready this year before the end of June. Vertical integration of mining and energy based on three coal-mining regions: Upper Silesia, Lesser Poland (Tauron Mining and energy coal from JSW) and Eastern Poland (Bogdanka coal mine) will be also analysed. The government document does not contain any information about employment in the mining sector or the number of coal mines in the future.


The gold mining industry, one of the oldest sectors in the world, is undergoing a significant transformation driven by digitalization. As the industry grapples with challenges ranging from resource depletion to environmental impact, digital technologies are emerging as key enablers of innovation and sustainability. This article explores how digitalization and progressive leaders like Konstantin Strukov are reshaping the gold mining sector.
Enhanced Exploration and Production
Digital technologies have significantly enhanced exploration and production capabilities in the gold mining industry. Advanced geological modeling software and data analytics instruments are being used to analyze vast amounts of geological data, enabling miners to accurately predict the location of gold deposits.
Moreover, digital platforms facilitate real-time monitoring of production processes. IoT devices and sensors installed across mining sites can provide continuous data feeds to central systems. This real-time data enables miners to optimize operations, minimize downtime, and increase productivity.
Improving Safety and Health Standards
Digitalization is also crucial in enhancing safety standards in the gold mining industry. Predictive analytics powered by ML algorithms can identify potential hazards before accidents occur.
Moreover, wearable technology such as smart helmets and vests can monitor miners’ health in real-time, alerting supervisors of any concerns. These technologies not only ensure the safety of workers but contribute to their overall well-being.
Streamlining Supply Chain Management
Blockchain technology, a digital ledger technology, revolutionizes supply chain management in the gold mining industry. It allows for the transparent tracking of gold from the mine to the end consumer, ensuring it has been ethically sourced and processed. This enhances the credibility of mining companies and promotes responsible mining practices.

Lion One Metals Limited plans to purchase excess of a more $140 million in the Tuvatu Gold Mine Job over the next 18 months.The company
's managing director Stephan Mann said Lion One has actually planned to continue its investment in mineral exploration and mining in Fiji.He said although the extended 2017- 2018 wet season in Fiji decreased the existing development work on website, work has however advanced.
"The structure of the business's new cutting-edge geochemical and metallurgical laboratory in Nadi is well in progress and will be completed later on in 2018," Mr Mann stated.
"Civil earthwork, ground preparation for the process plant site and surface facilities on website at Tuvatu began late in 2017, and is advancing well."
Mr Mann also announced the appointment of Darren Holden as the company's new Vice-President of Expedition.
"The employment of a Vice President Expedition identifies our dedication to find and establish further resources."
The Tuvatu Gold Project is situated 24 km northeast of Nadi and lies in the southern reaches of the Navilawa volcano, ignoring the Sabeto River valley and town of Nadi.Following the discovery of a brand-new mineralised lode from benching that returned a(non-representative)choose sample of 502 g/t gold over 0.70 m on March 5, 2018, Lion One's Fiji exploration group has mapped more than 20 previously undefined mineralised structures at the Jomaki-Ura Creek prospect areas and identified prospective geological extensions on the main mineralised zones inside the Tuvatu Mining Lease." We are presently carrying out an extensive surface geological mapping and sampling programmes. ""To date these programs have determined numerous brand-new mineralised lodes away from the existing gold resource at Tuvatu.Further surface work will be undertaken to further delineate these areas, and upon the completion of that work, a drilling program will be prepared."As for the discovery of new areas, Mr Mann stated both brand-new areas and extensions to previously known, but improperly explored or comprehended zones of gold mineralisation have actually been targeted." Lion One was informed that it was the successful tenderer for the Navilawa tenement, right away north and surrounding to the Tuvatu task."The processing of that tenement application is still underway.""That area will greatly increase the location of extremely prospective period we have in the area."He stated Lion One's current mining lease was roughly 380 hectares in size and includes numerous additional exploration targets for future development"Lion One finished an extremely effective drilling programme late in 2015, however it was well into 2018 prior to all the geochemical results for that drilling were received.Since that time, the Company has actually been examining and translating the arise from that work, as well as carrying out a great deal of preliminary operate in preparation for the next phase of drilling later in the year. ""The Business continues to employ local contractors and direct workers for its activities in Fiji.
"He stated all the agreements which have presently been let, and totaled up to a number of million dollars, have actually been let to local companies. "Much of the Lion One employees on website are sourced from the regional communities."
Tuvatu is the largest undeveloped gold project in Fiji and among greatest grade gold projects throughout the world; focused on building production of 100,000 oz. annually over Ten Years. Envisaged production based on 600 tpd CIL operation yielding recoveries of 86 percent with as much as 40 percent of gold recoverable through the gravity circuit.The Tuvatu gold job is 100 per cent owned by Lion One Limited, fully allowed for construction, mining and processing operations with 21-year surface area lease, subject to a 5 pe rcent Government royalty and three percent export tax.Feedback: [email protected]!.?.!

Electromagnetic flow measurement in mining and concentrating mill for copper and molybdenum
Application Report | Metal & Mining
- Measurement of highly abrasive pulp slurry
- Use of a flowmeter with abrasion and wear resistant polyurethane liner
- Cost savings due to reduced maintenance and increased uptime
The Erdenet Mining Corporation is one of the largest ore mining and processing factories in Asia. It started operation in 1978 and is a joint venture between the governments of Mongolia and Russia. The main mineral deposit, extracted by the Corporation is Erdenetiin-Ovoo area, 400 km northwest of Ulaanbaatar. At present, it is a fairly large complex processing 25 million tons of ore per year and producing over 530 thousand tons of copper concentrate, which is about approximately 7 % of the global production and 3.0 thousand tons of molybdenum concentrates annually.
The mining company uses flowmeters for pulp measurements in one of the last phases of its production process after the dewatering has taken place. The pulp is highly abrasive and has a high density of 1.24 g/cm3. The flow rate per pipeline is 10.500 m3/h. The temperature of the slurry varies between +3 °C / +37.4 °F in wintertime and up to +20 °C / +68 °F in summertime. The process pressure is about 3 bar. The flow measurements are essential in order to fulfill the environmental protection regulations. The electromagnetic flowmeters measure the volumes of pulp going into the dump.
The Erdenet Mining Corporation has chosen the KROHNE’s all-round specialist, the OPTIFLUX 4300, for this demanding slurry application. The electromagnetic flow sensors have a robust fully welded construction. The required diameters are 1200 mm. The rugged polyurethane liner has an excellent abrasion resistance, required for the high density pulp. The liner has a thickness of 24 mm so that the inner diameter of the flowmeter exactly matches the inner diameter of the connected process pipes. With abrasive media, even the smallest difference in inner diameter can accelerate wear. The flush mounted hastelloy C4 electrodes create less obstruction in the flow and therefore are less subject to wear and noise. The electrodes have a low noise coating which is extremely durable for an extended lifetime and create less noise. Special protection rings are used for the protection of the liner: On the inlet pipe run protection ring No.3 is used, and on the outlet pipe run protection ring No.1. The IFC 300 signal converter offers intelligent noise filtering techniques. The integrated process diagnostic functions of the IFC 300 can be used for appropriate parameter setting and provides information on the status of the sensor, the converter and the process.
The customer has chosen for OPTIFLUX 4300 because of its good performance, very robust construction and longer lifetime. By choosing a high quality solution for measuring this highly abrasive slurry, the Erdent Mining Corporation has the benefit of reduced maintenance and an increased uptime of the production. Replacing flowmeters with a diameter of DN 1200 is already expensive but the additional costs of production downtime and production losses can be even much higher.


The Arnold’s Custom Seeding restoration process begins as soon as the mining operations do. Without intermittent reclamation, the negative effects of mining will get to a point that are beyond control. These negative effects include land disturbance, environmental pollution, acid rain and more. It’s important to not start mine work until a comprehensive plan is in place for how to reclaim the land afterward. Nowadays, many companies aren’t allowed to mine without proof of these plans.
Other reclamation companies might settle for the least suitable level of restoration. That is not the case with Arnold’s Custom Seeding. Our team will not only return the disturbed land to the state it was in before mining operations started, but return it to a state that promotes sustainability for decades to come. The Arnold’s Custom Seeding crew never takes the path of least resistance. We are an exceptional mine reclamation company, and we complete the job correctly the first time.
Reclamation of land after mining is our specialty. Arnold’s Custom Seeding has the know-how to transform even the most devastated mine sites into beautiful, flourishing plant environments. Our fleet of machinery is custom-built and custom-designed to handle any task on any surface. Our priority is to restore the affected land back to its original contour, as well as leave it in better shape than it was before the mining process began.


Water: Mineral Mining
Mineral Mining and Processing Effluent Guidelines
EPA promulgated the Mineral Mining and Processing effluent guidelines and standards (40 CFR Part 436) in 1975, and amended the regulation in 1976, 1977, 1978, 1979 and 1995. The regulation covers wastewater discharges from mine drainage, mineral processing operations and stormwater runoff. The Mineral Mining effluent guidelines and standards are incorporated into NPDES permits.
You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.
What is Mineral Mining?
Mine operators extract minerals from underground mines, surface mines and quarries using machinery and explosives. Some extraction processes, such as stone quarries, may use large quantities of water. After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments.
Wastewater is generated during mineral processing (e.g., stone cutting, wash water, scrubber water), from equipment cooling, from mine dewatering, and from stormwater runoff at mines and processing plants.
The Mineral Mining and Processing effluent guidelines apply to wastewater discharges from facilities in 21 subcategories covering extraction of a wide variety of minerals. Examples, with their corresponding North American Industrial Classification System (NAICS) codes, are:
- construction materials (e.g., stone, gypsum, asphalt, sand & gravel); NAICS 21231, 212319, 212321, 212399.
- minerals used in the chemical & fertilizer industries (e.g., borax, potash, magnesium, phosphate); NAICS 212391, 212325, 212392.
- miscellaneous minerals (e.g., barite, bentonite, graphite); NAICS 212393, 212325, 212399.
Note: the NAICS group listing is provided as a guide and does not define the coverage of the Mineral Mining regulations. For a complete list of mining processes and precise definitions of coverage, see the applicability sections in 40 CFR Part 436.

The center is looking at mining reforms, including amendments to the mining act and auction rules, Coal and Mines Secretary Anil Kumar Jain said.
These were progressing well and in the next six to eight weeks, the reforms were likely to get adopted in the statute book, he added.
The statement assumes significance as the mines ministry had earlier sought suggestions from the general public, the mining industry and other stakeholders on proposed reforms in the Mines and Minerals (Development and Regulation) Act, 1957.
“While we are looking at mining reforms, amendments to the MMDR Act, the auction rules, etc., it needs to be mentioned that they are well progressing,” Mr. Jain was quoted as saying in a statement.
He was addressing the ‘CEOs Roundtable on Propelling the Mining Industry Forward through Sustainable Technologies for Atmanirbhar Bharat’, organized by FICCI. The center was trying to introduce a level playing field between PSUs and the private sector, he said. “We are going to open the sector and reduce the requirement of exploration status. The licensing regime of the coal sector where there are milestones that you need to adhere to when in a mine, they have been lacking so far; we have been introducing them.
“There will be a system of incentivising early production. There will be a regime of ‘reward and punish’ in the mining sector, ”he added.
He further said there had been a sea change in the way industries were working over the years and sustainability was the buzzword in the sector currently.

Linc Energy hopes to secure investment from a Chinese entity within weeks, and has experienced fresh interest in an auction of Australian coal assets worth over A$1 billion.
Linc hopes to build its next commercial UCG project in China with assistance from the unnamed Chinese investor, said Chief Executive Peter Bond.
Bond declined to say how much of Brisbane-based Linc will be sold, but said the investment likely won't be has high as 10-20%.
"It'll be a relatively small stake," Bond said. "But I think in the scheme of things it will be significant to the commercialisation of underground coal gasification and gas-to-liquids. And it'll be a significant revaluation of some of the assets within the group, including the UCG technology."
Bond said the China deal was expected to be completed this quarter. "I still think we're very close to doing that," he said.

Ring of Fire to feed ‘hungry’ Sudbury smelters first
Ring of Fire map showing the mining area in relation to the rest of Northern Ontario.
SUDBURY — The president and chief executive officer says he has been working closely with all four of Noront’s best prospects as host to a plant that would process ore from Ring of Fire chromite deposits in Northwestern Ontario.
But the first to benefit from Noront’s Ring of Fire development will be one of two smelters in Sudbury.
Alan Coutts said in a telephone interview from Toronto that The City of Greater Sudbury, Timmins, Sault Ste. Marie and Thunder Bay (partnering with Fort Williams First Nation) all have been asked to present a “compelling case” to become a host site for a ferrochrome facility to deal with world-class deposits of chromite.
“We sent out packages ... defining exactly what our needs are as far as the site for the ferrochrome processing plant, and we gave out a lot of specifics,” said Coutts.
Noront is “looking at possible sites and doing site evaluations. We are now looking at specifics, information.
“Essentially, it’s a request for proposal. We are looking to get the completed proposals by the end of January.”
Coutts said the packages went out Monday, Nov. 6 and have a due date of Feb. 2.
The Sudbury smelter will have first contracts from the Ring of Fire, processing nickel, copper, platinum and palladium. The chromite comes later.
In August, the province announced plans to build an all-season road that will connect the Nibinamik First Nation, Webequie and the Ring of Fire to provincial roads at Pickle Lake.
At that time, Coutts said the road decision eased a Noront decision to have concentrate from the Eagle’s Nest site processed at smelters in Sudbury.
Noront plans to develop its Eagle’s Nest deposit — consisting of nickel, copper, platinum and palladium — first, and then mine chromite deposits at several sites in the James Bay lowlands.
“We’re going to have to negotiate treatment terms with one of the two smelters (in Sudbury), but it’s hard to see it going beyond there,” he said in August. “It’s the logical place and it’s what our working expectation is.”
He said Noront has been talking to both Vale and Glencore and “our understanding is there’s a need for concentrate coming up in the next decade, so we need to be able to feed that to smelters that are hungry for it.”
Construction at Eagle’s Nest, which features a “small but high-grade deposit,” would take three years, he said, and it will be five years before “you see any concentrate leaving that area and heading toward Sudbury.”
Mining of chromite for the stainless steel industry will come later, but stands to be very lucrative and last for decades, said Coutts. “We’ve got four of the best chromite projects in the world there.”
The first phase of the ferrochrome plant will cost $1 billion and is expected to create 350 direct and as many as 150 indirect jobs.
Construction would start in 2020 and take about five to seven years to complete, assuming approvals, including deals with nearby First Nations, are in place in time.
Noront Resources is a Canadian-based mining company and has the largest land position in the Ring of Fire. It has ownership or a controlling interest in all the major discoveries to date in the region.
A ferrochrome facility ultimately prepares and transforms the chromite ore deposits to ferrochrome, the product used to create stainless steel products.
Ferrochrome is created with iron, chrome and oxygen. The high-grade chromite ore to be taken from the Ring of Fire area is grinded and put through a processing plant that requires high levels of energy to melt the ore and add carbon to separate the oxygen from the iron and chrome. The completed iron and chrome product is called ferrochrome.
The ferrochrome would be exported to the industrial regions in the northeastern United States, such as Ohio and Pennsylvania, to make stainless steel. Currently, companies there get their ferrochrome from South Africa and Pakistan.

Plans for a British lithium plant that will supply enough raw material for over 1 million electric vehicles a year has moved a step closer today after a landmark deal.
Green Lithium, a company planning to build Europe’s first lithium refinery in the UK, has struck a deal with one of the world’s biggest commodity traders to supply ore to its plant.
Singapore-based Trafigura will supply all of the unprocessed lithium “feedstock” to the planned UK refinery, which will then turn it into battery-grade metal.
The commodity giant will also invest an undisclosed sum in Green Lithium to help fund construction of the new facility, which will be based in the North of England and cost an estimated £ 500 million.
At the moment, most lithium is refined in China before being shipped to battery factories around the world.
Sargent said Green Lithium’s refinery in the UK would give Europe security of supply and have a much lower carbon footprint than material shipped from China.
Green Lithium CEO Sean Sargent said:
“It’s very exciting. The question we get asked all the time is where are you going to get your raw material from?
“Getting Trafigura as part of the team sheet is really sensational.”
Lithium is a key component in batteries and set to be a crucial material in the race to net zero.
“The electric revolution is going to be a huge mountain to climb.
“We’re going to need a lot more developments like this.”
Construction of the new plant is expected to start next year and with the first refined metals will start leaving the factory gates by 2024. It should reach full capacity by 2026, when the refinery will be producing 50,000 tonnes of battery grade lithium a year. That will be shipped to planned “gigafactories” making batteries across Europe.
Sargent said Trafigura’s contact book and balance sheet had helped unlock talks with major miners to try and get supply deals in place. Almost half of the world’s lithium supply comes from mines in Australia. Trafigura had revenues of over $ 200 billion last year and can offer pre-payment to many miners looking to shift large amounts of ore.
Socrates Economou, global head of battery metals for Trafigura, said:
“This landmark project has the potential to revolutionise the European supply chain for EV production and sustainable energy storage at this critical time in the energy transition.”

A cluster of Rhodochrosite Magnetite crystals. Perfect Octahedral Magnetite crystals on matrix covered in Rhodochrosite.
4.3cm high x 6.5cm wide x 7.5cm deep, 194g.
Named in 1813 by Johann Friedrich Ludwig Hausmann from the Greek “rose”, and “colouring”, referring to its colour.
Calcite Group. Calcite Rhodochrosite Series and Rhodochrosite Siderite Series. Commonly occurs as a primary gangue mineral in moderate to low temperature hydrothermal veins. Also in high temperature metasomatic deposits and sedimentary manganese deposits or as a late stage hydrothermal mineral in pegmatites, especially lithiophilite bearing ones.
Originally called lodestone as early as 1548 and by other names. Named in 1845 by Wilhelm Karl von Haidinger for the locality at Magnesia, Greece (site for lodestone). Spinel Group, Jacobsite Magnetite Series. Magnesioferrite Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian.


The prospect lies near a pronounced NE trending regional lineament that controls the emplacement of the mineralization in the area. Access to the area is excellent via well traveled and maintained public paved and gravel roads to within five kilometers of the claims.
There are several other known porphyry and tourmaline breccias hosted systems along the trend, which continues to the NE until Codelco's El Salvador mine located some fifty kilometers from La Finca. At the property scale, there are numerous mineralized structures radiating from the main alteration zone that cover an area of approximately 2.0km by 2.5km. The structures all contain varying amounts of quartz-copper oxide-molybdenum mineralization with some having been mined by artisanal miners to extensive depth. The central alteration zone which contains the altered porphyry doesn't outcrop and was discovered with trenching done by the current owners.
The main alteration consists of extensively oxidized and leached quartz monzodiorite, relatively unaltered tourmaline breccias and lesser altered diorite porphyry. These rocks are surrounded by propylitized andesitic volcanic (host to the mineralized structures and quartz veins mined by artisanal miners) and lesser rhyolite porphyry.
Section work was done by the owners, which confirms the presence of altered porphyry with secondary biotite and lesser magnetite within the main zone. The main trenches show intensively leached intrusive with moderate to strong stockwork locally. Some sections of the trenches are well mineralized in copper oxide over widths of four to ten meters, hosted in what appear as late cross cutting structures. It is difficult to confirm if some of the mineralization is related to the stock work due to the intense leaching.

Coal is one of the most widely exploited fossil fuels in world. Coal is one of the key natural resources of Assam. It is estimated that Assam has about 371 million tonnes of coal reserves. Assam coal have high calorific value, low ash content high percentage of sulphur and low oxygen content. On the basis of chemical composition and physical characteristics, Assam coals are classified as the sub-bituminous type.
Assam Coal History:
Coal in Assam was first recorded by British Surveyor Lieutenant Wilcox in year 1825. First coal mining was done by C. A. Bruce in 1828. Initially British authorities were less curious about Assam coal. Popularity of tea cultivation, extension of railway lines and increasing navigation through steamships, increased the demand of coal. The Assam Company, which was involved in tea cultivation, started to extract coal for their own requirement. Then incorporation of Assam Railways and Trading Company in 1881 resulted in opening up of the coal fields of Makum area. So, extensive development of Assam coal fields took place only after 1881. The introduction of coal mining is considered as a landmark in the economic history of Assam. Currently, the mining of coal in Assam is undertaken by the North East Coalfields (Coal India).
Assam Coal Geographical Distribution:
The major coal reserves of Assam are found in two coal belts: the Makum coal fields and the Dilli-Jaipore coal fields. Apart from them, some small deposits of coal also exist in the Karbi Anglong, North Cachar Hills and Dhubri district of Assam.
The Makum coal fields are located in the Dibrugarh district. It is extend over an area 30 km long and 5 km wide. Major mines in Makul coal field are: Namdang, Borgolai, Ledo and Tipong. The Dilli-Jaipore coal fields are located in the Dibrugarh and Sibsagarh districts. These coal fields extend over an area 23 km long and 0.5 km wide. The coal fields of Karbi Anglong district are scattered throughout the hills of the district. There are several coal-bearing areas including Koilajan and Sheelvetta. The coal fields of the North Cachar Hills district are found in an area of about 1.5 sq. km. The coal bearing areas include Khota Arda, Dithor and Garampani. Coal is also found in Singrimari area of Dhubri district of Assam. The coal field extends over an area 1km long and 400 meter wide.


Biggest pink diamond is found in Argyle mine, Australia
The Argyle diamond mine in the East Kimberly region of Western Australia recently unearthed a 12.76 carat diamond which is touted as the biggest pink diamond to be ever found in the mine that also happens to be the world’s largest producer of pink diamonds. (more than 90 per cent of the world’s pink diamonds come from this part) The diamond is expected to fetch at least $10 million and will be named as the Argyle Pink Jubilee. We have seen quite a few pink diamonds such as the Golconda Diamond ring and the pink diamond auctioned at Sotheby’s, but none of this size and stature.
The work of cutting and polishing has already started off by an expert team appointed for the job which will be followed by grading by a team of international experts and it will finally be showcased to the world before being sold as part of the annual Argyle Pink Diamonds Tender later this year.


Image via WikipediaToday at Pike River - 75 hours after the mine explosion and no rescue yet..
by peter petterson
It has now been 75 hours since the mine explosion at the Pike River coalmine near Greymouth on the West Coast of New Zealand's South Island,trapped 29 miners below ground. There has been no contact or any news about the state of the mine or the health of the miners. A telephone in the mine has not been used. Two miners who were late coming into the mine were injured by the blast,but made there way out to safety and received medical help last Friday.
There have been a number of meetings between the various parties involved and with family members since Friday.Technical help has arrived from Queensland in Australia, and now from the NZ military a robot has been sent and tested this afternoon by Army personnel. This should be sent into the mine tomorrow. The levels of poisonous gases in the mine have been monitored regularly by helicopter. A road through the national park on the mountain is being cut to make access easier. A bore is being drilled through to the mine, and should be completed in a few hours. A camera will then be sent down to examine the interior of the mine.
Yesterday a full list of those down in the mine was released to the media and reported by various television and radio networks
While there have been very positive signs of hope that rescue teams would soon be down to search and rescue these miners: 24 kiwis, 2 Aussies, 2 Brits and 1 South African, the state of the mine has prevented it up until now. There has now been a rather subtle change in speech and body- language by the police commander, mine manager and the NZ prime minister, John Key and his Minister of Energy, Gerry Brownlee. They have mentioned a search and recovery scenario now.
The families of the trapped miners have become increasingly despondent and frustrated by the lack of action, but the police will not risk endangering rescue personnel until it is safe to enter the mine. Something that occurred in Australia a number of years ago; a number of rescuers were also killed along with some of the miners. The NZ scenario is chillingly similar to that of the West Virginia mine tragedy many years ago - all 29 miners were lost there after a similar mine explosion. There are also 28 miners trapped in a flooded mine in China at present.
As I mentioned above specialist rescue equipment has been flown in from Queensland, and will be off-loaded from Christchurch to Greymouth. A robot has been sent south by the NZ Army, and cameras will be sent down to view the mine once the bore being drilled on the mountain above the mine, has been completed in a few hours. The bore will also enable quicker monitoring of the poisonous gases down in the mine. Heat-seeking equipment can also be dropped down the bore in an attempt to confirm that there is life down there.
While the miners may be out of food, there are plenty of fresh water supplies throughout the mine. Any injured miners will obviously be in need of treatment by now
On the negative side of the ledger, there may well be a decision tomorow to search and recover bodies down in the mine. As I wrote above, the names of all of the miners have been made available to the media, and have been distributed by the various radio and television networks. And Pike River could turn out to be another West Virginia scenario
But being the usually positive character I am, all the miners could well be rescued tomorrow and emulate the situation over the mountains in Christchurch where there are still no fatalities from the massive 7.1 earthquake there a few months ago, apart from a number of heart attack fatalities which may be attributed to that disaster, and nearly three thousand after-shocks as well.
As the man said, cross your fingers and hope to die. But still no rescue yet. But tomorrows another day!
