Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.
Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.

The Borehole Sites and Operations (BSO) Regulations were made under the Health and Safety at Work etc Act 1974 and came into force in 1995. Although many of the requirements in the BSO Regulations are now carried out routinely, they are still legally enforceable. From discussion with various people in the geotechnical industry, and with the HSE, these regulations appear to have largely been either forgotten or overlooked. The purpose of this article is to remind AGS members of the existence of these regulations and to provide a brief summary of what they entail.
The regulations can read be as a Statutory Instrument on: https://www.legislation.gov.uk/uksi/1995/2038/contents/made and also, together with HSE guidance in “A guide to the Borehole Sites and Operations Regulations 1995”, 2nd edition published 2008. A web-friendly version of the printed version, adapted for online use, is free to download from http://www.hse.gov.uk/pubns/books/l72.htm or it can be purchased from HSE Books (£18.00), ISBN 978 0 7176 6287 6.
The BSO Regulations are mostly intended to cover borehole operations for prospecting and extraction of minerals, but they also include boreholes for geotechnical investigation under the category of “Boreholes for any other purpose”.
The regulations require notification to the HSE of borehole sites and operations where the boreholes are 30m deep or more, and within a Mining Area. The boreholes may be being drilled in the future, are being drilled, or may have been drilled and have not yet been abandoned.
A Mining Area is defined as land which lies within 1000m, measured in any direction in 3 dimensions, of any mine currently being worked, or disused, or land where a licence to mine minerals has been granted for coal, natural gas, coal bed methane, or other minerals, in natural strata. Mines include shafts for access, ventilation or pumping, underground roadways, adits, and stopes but do not include opencast mines or quarries. Boreholes used for the storage of gas in natural strata reservoirs from which oil or coal bed methane has previously been extracted are also included as mining activities.
To find out if a site is within a coal mining area, you can visit the Coal Authority website https://www.gov.uk/government/organisations/the-coal-authority. Finding reliable information about areas where other minerals were mined requires more work, by reference to a variety of sources, although records may be sparse or uncertain. Reference to the shallow and deeper geology will give clues as to where these may be. Non coal mining can include ironstone, lead/tin, gold, phosphates, halite (rock salt), limestone, oil, gas and others including use of hydraulic fracturing (‘fracking’). However, open cast mining (including quarrying) is not included.
Boreholes for extraction of landfill gas, along with offshore installations or activities carried out from such installations, are excluded from the BSO Regulations. However, an installation that is connected to land by a permanent structure is not an offshore installation and would be included.
For drilling of boreholes 30 metres or more in depth, inside a Mining Area, Regulations 6(3) and 6(5) apply. These are as follows:
• Regulation 6(3): “Where a borehole is being drilled within a mining area to a depth of 30 metres or more, the person entitled to drill the borehole, within 30 days after commencement of its drilling, shall notify the Executive the particulars specified in Part III of Schedule 1 [see below].”
• Regulation 6(5): “The operator of a borehole site or, in the case of particulars previously notified under paragraph (3), the person entitled to drill the borehole shall ensure that the Executive is notified as soon as reasonably practicable of any material change of circumstances which could affect particulars previously notified under … paragraph (3)”.
Part III of Schedule 1 states that the particulars required for a notification to the HSE under Regulation 6(3) are as follows:
1. Name and Address of the person entitled to drill the borehole.
2. Particulars with scale diagrams, where appropriate, of:
a. the OS National Grid Reference of the location of the top of the borehole.
b. its directional path; and
c. its terminal depth and location.
3. A description of the operations to be, or being, performed and a programme of works which includes the dates on which operations are expected to start and finish, or (if past) the dates they started and finished.
The BSO Regulations are in addition to the Health and Safety procedures that are commonly carried out to meet current requirements and expectations applicable to ground investigation works. They are also additional to the requirements to liaise with and inform the Coal Authority when drilling in coal mining areas. There may also be requirements to liaise with other authorities for drilling in mining areas for minerals other than coal.

- How did Eldorado Canyon earn its "reputation for violence and lawlessness"?
Eldorado Canyon is located 39 miles southeast of Las Vegas. According to local lore, the Spanish explorers from Mexico and their Indian guides discovered gold in Eldorado Canyon as early as 1775. It was not until the news of a discovery of gold by Johnny Moss, a trapper who discovered ore in the Opal Mountains during the spring of 1861, that a rush of prospectors from California were attracted to Eldorado Canyon. Within a year, the Southwest Mining Company and El Dorado Mining Company had established working mines in the valley. The Techatticup Mine, which was the principal mine of Eldorado Canyon, opened in 1863. By this time four different townsites had been laid out, but the canyon was isolated, supplies difficult to bring in, and the camps had reputations for violence and lawlessness. In 1865 a post office was established, and in 1867 an Army Military Post was established to protect the steamboat traffic from hostile Indians. The Techatticup Mine was the most productive in the district, and by 1883 the company constructed its own fifteen-stamp mill to avoid the expense of freighting the ore for processing. With the coming of the railroad in 1905, mining revived in the district, and a fifty-ton smelter was developed seven miles west of Eldorado Canyon. A new townsite was laid out closer to the smelter and mines, and the older settlement moved to the new town of Nelson where a new cyanide mill was constructed to process the gold. Over half of the total production for the area was mined from the Techatticup mine.
- How has the value of the following metals changed over the years: gold, silver, platinum, vanadium, and lead-zinc?
Goodsprings, located 34 miles southwest of Las Vegas, was once well-known for its gold, silver, platinum, vanadium, and lead-zinc. Silver ore was discovered in 1868, and the area was incorporated into the New England Mining District, later renamed the Yellow Pine Mining District. Shortly after the discovery, the site was abandoned because of the low grade of the ore. The town reemerged in the 1890s when a prospector, Joe Good, opened a mine in the area. The local springs and the city were named after him. In 1893 the population was only 200 strong, and most of the residents worked in the Keystone Gold Mine that was opened in 1892. The Yellow Pine Mining District, comprising several smaller sites, opened in 1901. The San Pedro, Los Angeles, and Salt Lake Railroad’s depot in the neighboring community of Jean stimulated the economic development in Goodsprings, leading to the reorganization of the Yellow Pine Mining District in 1906. To increase its production, the district built a narrow gauge railroad from Goodsprings to Jean in 1911 that drastically reduced shipping costs. Previously, ore was carted to the railroad in Jean by an eight-horse team. Goodsprings grew into a modern community with several stores, a school, hospital, and post office. In 1910 an oval race track opened and hosted car races several times a year. The town also had one of the finest hotels in the region, the Hotel Fayle, named for George Fayle, the owner, which opened in 1916. The hotel had twenty rooms with private baths and a banquet hall where local dances were held with live bands imported from Las Vegas. Goodsprings peaked in 1915-1918 because of the demand for metals during World War I. After the war the district dwindled, and became dormant by 1922.
- What affect did the varying types and qualities of metals and minerals found at Potosi have on the life of the community?
Potosi, the oldest lode mine in Nevada, is located 25 miles southwest of Las Vegas. According to legend, Potosi was named after one of the greatest silver mines in colonial Mexico; however, other accounts claim that Nathaniel Jones, a Mormon settler who discovered lead deposits in 1856, named the mine and its small community after his childhood home in Wisconsin. Lead was mined sporadically there through 1857, but was too brittle and flaky to be profitable, and the mine and settlement were abandoned when the Mormons left their Las Vegas mission. In the spring of 1861, the Colorado Mining Company opened a smelter near Potosi Springs and mined silver there until 1863. In 1870 the Silver State Mining Company reopened the mine. From 1873-1906, production was very inconsistent until the San Pedro, Los Angeles and Salt Lake Railroad finished its line through Southern Nevada. Mining at Potosi suffered from the financial recessions of the following years until late 1913, when the Empire Zinc Company took over production and Potosi became the largest producer of zinc in the state. The mine suffered from the post war recession, and despite a small boom in 1928, never regained a constant level of production.
- What role did music play in the history of Southern Nevada?
- What characteristics defined each city in Southern Nevada?
Gold ore was first discovered in Searchlight by Paiute Indians in 1870, 55 miles south of Las Vegas, but it was not until 1897, when G.F. Colton, a notable prospector, discovered a rich gold vein and word spread, that Searchlight boomed. The following year, the mining district was fully organized. The Quartette Mill opened in 1898 and soon became one of the city’s finest producers. In 1902 the first newspaper, Searchlight, began publishing, and a twenty-stamp mill was constructed by the Duplex Mining Company. In 1903 a miners’ strike brought the town’s production to a standstill until the mining companies brought in non-union miners to work the mines. The boom peaked during the spring of 1907 when the first train of the Barnwell & Searchlight Railroad arrived in Searchlight’s station to a warm greeting of a fifty-piece cowboy band. In 1907 Searchlight contained over forty-four working mines and a population of 5,000. However, Searchlight was hard hit by the financial panic of 1907.
The city recovered after a number of years and by 1910 was noted for its fashionable and modern amenities and its commuter train. The community boasted a luxurious hotel, several saloons, a barbershop, lumberyard, shops, cafes, union halls, boarding houses, schools, several stables, the newspaper, and its own hospital. The biggest mines were the Quartette, Cyrus Noble, Little Brown Jug, Old Bottle, and Duplex, whose gold production totaled $7 million. In 1934 a flotation mill was built and a 30-ton custom mill ran briefly in 1935. However, by the late 1940s, little was left of the once modern boomtown of Searchlight.

Insights on the nitrate reduction and norfloxacin oxidation over a novel nanoscale zero valent iron particle: Reactivity, products, and mechanism.Sci Total Environ. 2019 Apr 10; 660:541-549.ST
Herein, the application of a novel acid mine drainage-based nanoscale zero valent iron (AMD-based nZVI) for the remediation of nitrate and norfloxacin (NOR) was studied. Experimental results indicated that the catalytic reactivity of AMD-based nZVI toward nitrate reduction was superior to that of iron salt-based nanoscale zero valent iron (Iron salt-based nZVI). The presence of ultrasound irradiation could significantly enhance the reactivity toward both the nitrate reduction and NOR oxidation processes. The optimal efficiencies of nitrate and NOR by AMD-based nZVI/US process could be kept 96 and 94% within 120 min, respectively. Ammonia was identified as a major product in nitrate reduction process, while three oxidation products were observed in NOR degradation process. Both reduction reaction of nitrate from AMD-based nZVI and oxidation reaction of NOR from US-assisted Fenton system might be involved in AMD-based nZVI/US process. The AMD-based nZVI/US process showed a better performance on the removal of NOR compared with that of nitrate. The findings of the present work could be as a guide and show that AMD-based nZVI/US process is feasible for the remediation of both nitrate and NOR in real wastewater.


Call for ‘nationally important’ coal mine which supplies Tata Steel to stay open
Anthony Lewis, Local Democracy Reporter
Operators of a coal mine in Merthyr Tydfil want to keep mining there for nine more months to keep the steel industry in Port Talbot supplied and help with the security of energy supply.
Merthyr (South Wales) Ltd is applying to vary a condition of its planning permission for the Ffos y Fran coal mine site so it can keep extracting minerals until June 6, 2023 and to extend the deadline to complete the restoration of the site until September 6, 2025.
Planning permission for the operational surface coal mine at Ffos-y-Fran was originally granted by what was then the National Assembly for Wales in April 2005, later varied with two conditions which said all coal extraction from the development should stop no later than September 6, 2022 and final restoration of the land shall be completed no later than December 6, 2024.
The section 73 permission allowed “the limited dispatch by road of up to 5% of the annual output of coal from the Ffos-y-Fran land reclamation scheme or a maximum of 50,000 tonnes of coal per annum (whichever is the lesser) via Cwmbargoed Disposal Point”.
Cwmbargoed Disposal Point – which handles the coal produced from the site – operates under its own planning permissions and is partly in Merthyr Tydfil but mostly in the Caerphilly County Borough.
The section 73 application was originally refused by the council but the proposals were allowed on appeal with a list of updated conditions for the continued operation of the mine which superseded the original planning permission for the site.
The reasons given for needing to extend the time include allowing for full extraction of the consented area which has been impacted by the working practices required during the Covid-19 pandemic and allowing for continued supply of coal to the steel industry in Port Talbot [TATA Steel].
The third reason is to allow for a new planning application related to a three year extension to coal operations at the site to help with the security of energy supply issues affecting the steel industry in south Wales and put a revised final site restoration plan in place.
Only Welsh source
Since the closure of Tower Colliery, Ffos-y-Fran represents the only current source of Welsh dry steam coal within the country, the statement said.
It said that dry steam coal has unique characteristics which are ideal for use in steel manufacturing and that TATA Steel relies heavily on this coal.
It said: “Therefore, without the continued provision of the coal from the Ffos-y-Fran site, users of Dry Steam Coal (such as TATA Steel) would need to import suitable coal products from Russia, Venezuela or Australia.
“This is an unsustainable practice and results in an increase of Carbon footprint of such operations given the transit miles required (in comparison to extracting and utilising a locally sourced coal).
“Consideration should also be given to the security of supply given the geo-political situation and the sustainability of supply from such regions.
“Whilst there is a longer term aspiration for Carbon neutrality within the UK, industries such as steel manufacturing are in a period of transition and require a security of supply in the short term.
“As such, the ability to continue extracting dry steam coal from Ffos-y-Fran should be considered of national significance / importance.”
During the coronavirus pandemic, the number of workers on site was reduced and as a result less coal was mined in 2020, 2021 and part of 2022.
The exact numbers are not known but the planning statement said that with approximately three quarters of the usual number of miners on site operating a single shift, this reduced the extraction rate at the mine by in excess of 120,000 tonnes a year.
It added that it is estimated that there is approximately 240,000 tonnes of coal left within the remainder of the last cut within the confines of the previously consented extraction area.
The statement also said that any reduction in tonnages extracted from the site would impact upon payments (per tonne) made to the community fund managed by Merthyr Tydfil Council, the money paid into the restoration fund and money paid to the Coal Authority.
It added: “Overall, the unforeseen circumstances that led to the above should be considered to form grounds for an exceptional case.”
The planning statement said the Ffos y Fran Land Reclamation Scheme, which covers around 400 hectares (Four square kilometres) is the last part of the East Merthyr Reclamation scheme, which is made up of three phases of extraction and reclamation at the site.
This final phase, which started in 2007, will restore derelict land after extracting an estimated 10 million tonnes of coal.
This includes the removal of known shafts previously associated with iron ore and coal workings, removal and remediation of areas of landfill, and the restoration of the site to common land and grazing.
The planning statement also said that because the proposals will not alter the working practices or physical extent of the minerals extraction proposed, the section 72 application would not raise likely significant effects beyond those assessed within the original Environmental Impact Assessment (EIA).
Welsh dry steam coal sourced from Ffos-y-Fran is also utilised by a variety of smaller markets, including steam locomotives, traction engines, steam-powered boats and steam raising boilers.

What do Mining and Petroleum Engineers do?
In simple terms, a mining engineer evaluates, plans, and oversees the construction of a mine. A mining engineer will be involved in a project through all phases of mining operations – from exploration and discovery of the mineral resource, through feasibility studies, mine design, development of plans and production, scheduling, operations, processing and even marketing. They are still involved at the mine closure stages including final land restoration and rehabilitation.
What do Mining Engineers do?
- Investigate mineral deposits and work with geologists, other earth scientists and economists to evaluate them and determine whether they can be mined profitably.
- Look at the depth and characteristics of the mineral deposit and its surrounding to work out the most suitable mining method.
- Carry out the mine design including all the relevant mine planning and scheduling using state-of-the-art mine planning and visualisation software.
- Plan and coordinate the employment of mining staff and selection of equipment with regard to efficiency, safety and environmental conditions.
- Talk to geologists and other engineers about the design, selection and provision of equipment, facilities and systems for mining, as well as infrastructure such as access roads, water and power supplies.
- Oversee, in conjunction with mine management the mine construction and implementation of mine plans.
- Take on responsibility and leadership for production crews and operational mine performance.
- Conduct ongoing research aimed at improving efficiency and safety in mines.
Petroleum Engineers are employed by oil or gas companies to design, test and implement efficient methods to extract petroleum products from the earth and sea floor. They spend most of their time making estimations because they can never see what is actually going on thousands of meters below the ground. They work closely with other professionals, such as geologists, to locate the dig site, design and build the machines that extract as much oil and gas as possible, and oversee the removal and processing of the petroleum itself. All this, while working to keep costs low.
To help with the company’s decision making, a Petroleum Engineer may research and present the findings to a company’s management. Petroleum Engineers need to determine whether the cost to remove the ‘crude materials’ from the ground is low enough compared to the money earned from selling the refined products. Petroleum Engineers are highly sought after because the world has such a high need for hydrocarbons as a fuel source. Many petroleum engineers work for some of the biggest companies in the world and, in most cases, are the best paid compared to other engineering disciplines.
What do Petroleum Engineers do?
- study geological and geophysical information to determine the most efficient drilling method and equipment to use
- develop tools, machines, and equipment used to extract petroleum products
- operate software used to control and run the machines
- oversee teams employed on a job site

Hydrogeochemical assessment, water treatment and revalorization of dumps, tailings and drainages produced at phalaborwa industrial complex
Department / other collaborators
PublisherUniversidad de Huelva
AbstractThe Phalaborwa Industrial Complex is formed by several mines and factories that extract value out of the geological formation named Phalaborwa (or Palabora) Igneous Complex (PIC). The industrial activity started in 1950’s with the extraction of phosphate rocks and Cu. Since then, more than 4500 Mt of solid waste enriched in magnetite, Zr, Ni, Au, Ag, Pt and rare earth elements (REE) have been accumulating in PIC area in the form of tailings and waste rock dumps, as well as above 3 Mm3 of industrial wastewater, including rock drainages and process water. Due to the industrial activities, the water quality of the aquifers underneath PIC has been deteriorated reaching up to 10 g/L of sulphate, particularly surrounding the impoundment dams of the phosphoric acid plant from the fertilizer industry. The groundwater quality at PIC and the efforts to restrain the contamination plume by using abstraction boreholes resulted in a continuous rise of pollution within PIC facilities but it helped to control the migration of the plume beyond the industrial area. However, this study goes beyond the environmental assessment, it is a comprehensive evaluation of PIC’s wastes, which led to the revalorization of the mining wastes as potential REE resources and as neutralization reagent and culminated with the design of a system that would bring benefit from both characteristics of the wastes. The mineralogical and geochemical study of the PIC’s mine wastes was conducted under the hypothesis that the abundance of REE from the ore and host rocks mined from PIC might be preserved or even enriched in the mining wastes. The abundance of REE minerals (mainly monazite) and REE-bearing minerals (mainly fluorapatite, calcite and dolomite) confirmed that hypothesis and suggests the economic potential of PIC wastes as secondary source of REE. The most profitable REE are Nd, Dy, Pr and Tb (87% of net value). The tailings are economically more attractive than the WRDs because the mineral processing has generated tailings of mostly monomineralic particles enriched in REE. The environmental characterization of PIC wastes was carried out in order to evaluate its potential as neutralizing reagent for passive water treatment. The mining waste used to treat acid industrial wastewater (AIW) need to accomplish two main characteristics i) high neutralization potential and ii) low toxicity. National and international procedures were carried out to assess the neutralization potential and the toxicity of the leachate that could be released from each rock and each tailing. The results of this investigation showed that none of the PIC rocks have the potential to produce acid rock drainage. It also demonstrated that the carbonatite rocks and the tailings from the copper plant (herein named East tailing) exhibit the highest neutralization potential (up to 800 kg CaCO3 eq/t). According to the National Environmental Management Waste Act (59/2008) of South Africa, PIC wastes classify as Type 3 waste (non-hazardous). PIC wastes would mostly release non-toxic elements such as Ca, Mg, SO4, Na, P, K and Fe. Among PIC wastes, East tailing would the best option as alkaline reagent to neutralize AIW. The knowledge acquired at this point of the investigation served to develop a system that could remediate the extremely acidic wastewater from the neighbouring phosphoric acid plant. This system would be a near-zero waste if the substrate used get enriched in REE and become a marketable by-product. The material from East tailing was selected for its abundance of REE minerals and REE-bearing minerals, as well as for its neutralization potential (reactor A). A BDAS reactor (Barium carbonate Dispersed Alkaline Substrate) was added to the system to reduce the hardness and to further improve the water quality (reactor B). The bench scale prototype was able to remediate the extremely AIW from the phosphoric acid plant and, at the same time, to concentrate the REE contained in both the water and the tailing. The treated water complies with WHO (World Health Organization) guideline for drinking water for all the parameters except Ni, Cd and occasionally Ba. Mineralogical and geochemical analyses showed that the REE concentration increased from the initial 1.3 g/kg up to 2.1 g/kg in the central area of reactor A. Most REE precipitated as newly formed REE-rich Ca-Al-F phosphate. Minor concentrations of REE were found in reactor B, together with most of the radionuclides. Altogether, the findings of the thesis bring to the table an eco-friendly and sustainable alternative to concentrate REE in a circular economy approach, while improving the quality of the extremely acidic wastewater.

As well as the model of the village there is a model of the mine workings in the Blacksmith's Shop. It shows where the veins of lead ore are located under the village and the various tunnels and shafts that were dug in order to extract it.
When we talked with Colin at the Mining Institute he told us how the mines were put to bed in the late 1800's. Cheaper imports of lead ore were coming into Britain from Northern Europe so it was no longer a profitable operation to extract lead ore at Allenheads and WB Lead withdrew from the area. However, they did not just up sticks an leave. Colin told us that underground machinery was carefully wrapped up. Copious amounts of tallow (animal fat) was applied to preserve metal from deteriorating in the wet conditions. At the time they must have thought this was just a temporary suspension of works and that the market might recover and they would recommence mining in Allenheads, little did they know that these mines would not be worked for lead ore again in their life times. In fact, apart form a brief exploration for Fluorspar by British Steel in the 1970's these mines have remained dormant for over 100 years.


The importance of critical minerals should not condone their extraction at all costs, says researcher
Global warming is real and climate change is worsening day-by-day with raging forest fires, unseasonably warm winters and flooding disasters taking place across Canada. Meanwhile, the carbon-zero transition required to move away from such a dire future is hampered by a key weakness—"critical minerals."
The energy transition depends on so-called "battery" or "critical" minerals to be successful—minerals which must be mined or recycled. Smart phones, superconductor chips, renewable energy technologies and even the defense industry all rely heavily upon critical minerals. Demand for these minerals is set to triple by 2030.
However, the uncomfortable reality is that the supply of these metals is simply not there, and their extraction carries huge social and ecological risks. This problem affects us all.
What are critical minerals?
There is no universal consensus on what critical minerals are. Various countries and bodies such as the International Energy Agency or the World Bank have different lists and the contents of these lists do not remain static.
For instance, the Canadian Critical Minerals List contains 31 minerals or mineral groups. The United States has two lists: the U.S. Geological Survey Critical Minerals List that contains 50 individual minerals and the Department of Energy Critical Materials for Energy List, which adds energy materials like copper and silicon. The European Union has a list of 34 Critical Raw Materials.
The term "critical mineral" is technically a misnomer as most of the elements on these lists are metals and not minerals. However, there are broad areas of agreement: most lists include battery metals such as lithium, nickel, cobalt and copper, as well as rare earth elements and platinum group metals. Other common elements are the alloys of steel, such as chromium, manganese and zinc.
All of these elements are crucial to the energy transition. Battery metals power electric vehicles and storage batteries, steel and rare earth elements are imperative for wind turbines and copper is essential for power grids. Simply put, shortages in critical minerals mean a delayed energy transition and worsening climate impacts.
Yet electric vehicles are only as "clean" as the electricity grid that feeds them. They are only as "green" as their component parts. The batteries require nickel, which could well have come from a mine in the Philippines that legally dumps its tailings (toxic waste) in oceans. Meanwhile, the vital cobalt can't be separated from the human miseries of mining in the Democratic Republic of the Congo—a mining industry referred to as "a new form of slavery, a subterranean slavery."
Why are critical minerals problematic?
Critical minerals are often found in deposits that are highly concentrated geographically, and China is a dominant force in their processing and supply. This means that geopolitical tensions can make it harder to secure critical mineral supply chains.
A December 2023 World Economic Forum White Paper maps ecosystem risks arising from a lack of supply in critical minerals. Its conclusions are clear.
Not only does a delayed energy transition await us at the end of the road, but the signposts along the way indicate that these risks are already playing out.
For instance, political risks identified include conflict over resources, increasing resource nationalism and increasing trade fragmentation. Among the economic risks are market volatility and uncertainty, as well as stockpiling of critical minerals.
The impacts of critical minerals mining
When considering the implications of minerals shortages, it may be tempting to justify critical minerals mining at all costs, however, this is a dangerous fallacy. The social and environmental impacts of poorly mined critical minerals are dire.
These range from lithium's water intensity in the fragile landscapes of the Chilean Atacama desert to the toxic processes inherent in the processing of the rare earth elements whose use is ubiquitous in smart technology and wind turbines. Diminishing ore grades mean ever bigger tailings dams, and climate change makes them more prone to accidents.
For Indigenous communities, critical minerals hold both promise and peril. Studies have shown that critical minerals are often heavily concentrated on Indigenous lands. For them, the question arises whether this will open the door to Indigenous economic development or if it will constitute yet another instance of displacement and ecological destruction on their doorstep.
The importance of independent standards authorities such as the Initiative for Responsible Mining Assurance (IRMA) cannot be overemphasized. In contrast to industry standards such as Towards Sustainable Mining, IRMA represents multiple stakeholder views. These include communities, employees, investors and mines.
Mining is by its very nature a highly energy intensive process. While it is expensive and technically complex to retrofit existing mines for electrification purposes, new mines should be designed with carbon neutrality in mind. Of course, this can be particularly difficult in places that are experiencing infrastructure challenges, such as limited renewable or low carbon energy options.
Greenfield mining is not the sole solution to the critical minerals conundrum. Urban mining (extraction from electronic waste) can play an important role. It's also important to design products manufactured from critical minerals with recycling and repurposing in mind.
By investing in research and development, we can find substitutes to the most problematic minerals, whether the underlying issues are geopolitical constraints, toxicity or human rights abuses.
The bottom line
At the end of the day, we need responsible mining practices that will enable us to obtain the minerals required to make the energy transition work. However, we must do so in a way that is just and equitable towards both people and the planet.
This goal is a race against time, requiring both innovation and a never-ending vigilance against a lowering of standards to meet short-term needs—a vigilance which we all must work to maintain.

Regulation of the Minister of Energy and Mineral Resources No. 1 of 2014 (hereinafter referred to as ‘Regulation 1/2014’) contains provisions concerning the upgrading of added value of minerals through mineral processing and refinery. In order to implement the provision of Article 96 and Article 112 C point 5 of Government Regulation No. 23/2010 (latest amendment 2014) regarding the Executing of Mineral and Coal Mining business activities, it is necessary to stipulate Regulation 1/2014. The Regulation comes into force as from the date of promulgation, which is 11 January 2014.
There are several types of minerals: metal mineral, non-metal mineral, and rocks. Added value means an addition to the value of minerals as a result of the mineral processing and/or refinery. The upgrading of added value means the increase in the value of minerals through the processing and/or refinery and will have the result of economic, social, and cultural benefits.
Procedures for upgrading added value of minerals
The processing and/or refinery of minerals shall be executed on the basis of considerations:
a. Having ore resources and reserves in a large quantity
b. Driving up metal production capacity in the country
c. Processing and/or refinery technology already in the proven phase
d. End product of the processing and/or refinery as raw material of industry for the domestic need
e. By product constituting rest of the processing and/or refinery production for raw material of domestic chemical and fertilizer industry
f. As raw material of domestic mineral-based strategic industry
g. Contributing multiplier effects to the state economically and socially and culturally
h. Increasing state revenue
The processing takes place in the country in accordance with the minimum content of the processing as contained in the Attachment of the Regulation.
The upgrading of added value
IUP of Production Operation is a business license granted for the completion of IUP of Exploration to execute the phase of production operation activity. Besides IUP of Production Operation, there is IUPK of Production Operation with regards to special mining business license area. Holders of IUP(K) of Production Operation for metal mineral, non-metal mineral and rock are obliged to process their mining production in the country in accordance with the minimum content of the processing of the specified mineral. The processing and/or refinery may be executed directly or through cooperation with other holders of IUP. In some cases of joint cooperation, approval is needed from the Minister.
Obligation of holders of IUP, IUPK and special IUP
Holders of IUP or IUPK for copper production operation are obliged to fulfill the minimum content of the purification of metal minerals as contained in Attachment I of Regulation 1/2014. The same applies for lead, zinc, iron sand, and tin.


Rare earth elements are a key strategic resource for the 21st century. Although the global market is small compared to commodities such as oil or steel, with only 125,000 to 130,000 tons produced worldwide, rare earths are vital in the production of electronics, aerospace and defense products (including advanced sensor systems and guided missiles), and alternative energy technology, particularly wind turbines and batteries in electric and hybrid vehicles. Increasing consumption of these end products is currently fueling global demand for rare earths.
China currently dominates the supply-side of the rare earths market. As mines elsewhere in the world were closed due to lax environmental regulations, Chinaâ€™s low labor costs have propelled state companies to the forefront of the market. Despite the promising market outlook, China has restricted production and export of rare earths in a bid to bolster its domestic alternative energy industries. In 2010, export quotas are slated for a 40% reduction to further preferential access for indigenous producers and foster growth and competitiveness.
In an effort to offset Chinese export restrictions, there are plans to expand production. The Mountain Pass mine in California, the former leading global supplier of rare earths, is slated to reopen by 2011 and Australian mining firm Lynas has opened a mine at Mount Weld in Western Australia. The Japanese government is supporting efforts to exploit rare earths to exploit rare earths in Kazakhstan, Canada, South Africa and Vietnam.
Foreign responses to Chinaâ€™s increasing restrictions on rare earths are creating tensions that could create resource nationalism or stoke protectionist sentiments that could disrupt the global rare earths market. Major importers such as the United States and Japan are also considering creating rare earth stockpiles. While these would provide a secure supply during times of crisis, the purchases necessary to create a stockpile could cause short-term spikes in the rare earth market and worsen the supply crunch caused by Chinese quotas.
The concurrent trends of growing demand for rare earth metals and export restrictions from the worldâ€™s largest producer, places pressure on international consumers of rare earth metals and their finished products. While demand will encourage development of new rare earths sources, it is unclear that alternative sources of rare earths are sustainable without significant political and economic support from governments. Furthermore, it is also uncertain as to when production from these new sources will be able to meet the rising demand. Should China maintain its monopoly over rare earth production, the production of alternative energy and other green technologies is likely to skew toward Chinese industries and with them an important source of growth and employment in the coming decades.

Additional Physical Format: Online version: Franklin, John C. Polymeric sealant used to stop shale degradation in coal mines. [Washington]: Dept. of the Interior, Bureau of Mines, The Bureau of Mines substantially reduced shale degradation in a coal mine by two spray coat applications of a water-base epoxy sealant.
More t square feet of passageways were treated, and in 18 months only one failure occurred. This failure was due to improper spray application. Oil shale can be used as a fuel in thermal power plants, wherein oil shale is burnt like coal to drive the steam turbines.
As ofthere are oil shale-fired power plants in Estonia with a generating capacity of 2, megawatts (MW), China, and Germany. Also Israel, Romania and Russia have run oil shale-fired power plants, but have shut them down or switched to other fuels like natural gas.

In22 million tons of oil shale were produced from six room-and-pillar underground mines and three open-pit mines (Opik, ). Of this amount, 81 percent was used to fuel electric power plants, 16 percent was processed into petrochemicals, and the remainder was used to manufacture cement as well as other minor products.
The mining of oil shale requires large amount of water. Explanation; -Oil shale is a sedimentary rock filled with kerogen. It can be processes to produce shale oil (a liquid form of petroleum). It forms when kerogen was not buried deeply enough or was not subject to enough.
COAL, OIL SHALE, NATURAL BITUMEN, HEAVY OIL AND PEAT – Vol. II - Mining of Oil Shale - Ingo Valgma and Jialin L. Qian ©Encyclopedia of Life Support Systems (EOLSS) About 85% of oil shale mined is used for burning in oil shale power stations; 12% for retorting for obtaining shale oil; about 3% for cement factories.
Dangerous Method - Tunnel deep into tin, lead, copper, coal, and other mineral seams. Mine tunnels ocassional collapse, and natural gas in coal mines can explode. Water seeping into mine shafts also dissolves toxic materials, contaminated water seeps into ground water, pumped to the surface, enters streams and lakes.
In Pennsylvania mines are engaged in producing its million tons of coal each year, while in Wyoming only 35 mines are responsible for its million ton production level. As we will see in following sections, the methods of mining, the problems encountered in mining, and even the solutions to those problems, are different in the.INDIAN COAL MINES” submitted by Sri Abhijit Sahoo in partial fulfillment of the requirements for the award of Bachelor of Technology degree in Mining Engineering at National Institute of Technology is an authentic work carried out by him under my supervision and guidance.The mining depth is increasing, and mining activities are moving from surface to underground mines.

At a recent gala, the State of Colorado and the Colorado Mining Association (CMA) recently honored four companies and three individuals for their excellent safety practices last year.
The awards were given out at the 118th National Western Mining Conference & Exhibition in Denver.
Stuart Sanderson, president of the CMA, handed out the awards.
Mountain Coal Company LLC and its West Elk Mine, located in Gunnison County, earned the safety honor for the fourth consecutive year. This mine posted the lowest total for underground mine incidents in the state. The company reported just 0.77 incidents for every 200,000 man hours spent at the mine. This figure is based on a total of 781,726 man hours.
In addition, Western Fuels Colorado LLC earned four different safety innovation awards. The company's two surface mines also earned outstanding safety-performance awards.
The smallest coal mine safety honors were granted to Western Fuels-Colorado LLC's New Horizon Mine in Montrose County. The mine has not recorded any lost time due to an accident since September 2010.

Ahead of the Budget, Mines Ministry has sought from the Finance Ministry reduction of export duty on low grade iron ore by 50 per cent to boost production to enhance export of the mineral.
"We have sought reduction in the duty on fines to 15 per cent from the Finance Ministry. Now they have to decide it. Presently there is a uniform duty of 30 per cent on both, iron ore lumps and fines," Mines Minister Dinsha Patel said here.
Shipment of Fines, having low iron content and constituting around 92 per cent of the total iron ore exports, were at 60 million tonnes (MT)in 2011-12, data compiled by
mining industry body, FIMI, showed. This is in contrast to about 120 MT exports achieved in 2009-10.
Between April-November, 2012, total iron ore exports were at 15 MT, down over 62 per cent compared to the same period of previous year, the FIMI data says.
According to the industrial production (IIP) data, mining sector has shown a negative growth of 2.6 per cent in the first nine months of the current fiscal and has widened from the previous year's level of (-)1.9 per cent.
In December, 2012 itself, mining sector had a negative growth of 3.3 per cent. Iron ore, a key raw material for steel production, is one of the major components in the mining index of IIP data.
When asked about the demand of domestic steel industry for a complete ban on iron ore exports, Patel said, "Whatever is domestic demand should be made available, there should not be any shortage but lower grade iron ore, which cannot be utilised here, what do we do with them if we don't export."
"Whoever is saying that iron ore is not available (for the domestic steel industry) is not correct. I am not willing to accept it,", the Minister said.

(Updates number of rescued workers)
Sept 28 (Reuters) - Vale SA said on Tuesday that 35 of its employees who were trapped in a Canadian mine had returned to the surface and four more were on their way out.
On Monday, the Brazilian miner said 39 mine workers had been trapped underground since Sunday at its Totten mine in Sudbury, Canada.
Vale said earlier on Tuesday it expected all employees to surface by late morning, but in an afternoon statement it said that four still remained underground.
The accident at the copper, nickel and precious metals mine occurred when a vehicle transporting the workers was taken offline.
After that, employees went to refuge stations and kept in communication with the company, with access to food and water.
Vale said all rescued workers are in good health. (Reporting by Arunima Kumar in Bengaluru and Rodrigo Viga Gaier in Rio de Janeiro; Additional reporting by Jake Spring in Brasilia; Editing by Krishna Chandra Eluri, Marguerita Choy and Richard Pullin)
