Iron and Steel
USAGE OF LIME IN IRON AND STEEL INDUSTRY
Quicklime - both high calcium and dolomitic - is used most commonly in the iron and steel industry to purify the steel in the electric arc furnace (EAF) and in blast furnaces. Lime is particularly effective in treating phosphorus, sulfur and silica and, to a lesser extent, manganese. Lime also has important uses in the secondary refining of steel and in the manufacture of steel products.
Electric Arc Furnaces
In electric arc furnaces, scrap iron and steel, pig iron, iron ore and enriched iron ore are placed in an oven and heated by the use of heat from electric current. A lime flux is added with a mixture of quicklime or slaked lime and dolomitic lime. The total amount of flux is used around 50 Kilograms per tonne of steel (up to 50% can be dolomitic lime).
The benefits of lime flux: The lime flux purifies impurities and forms a slag that can be separated from the steel and is removed from the oven as a liquid. It also reduces refractory wear and gassing and can provide foam slag for long arc operation. lime is used unless special product is required by special furnace injection applications.
Limestone Use in Blast Furnaces
Iron is generally produced by burning iron ore (Fe2O3, Fe3O4) in the blast furnace (more than 100 m) with coke and air in reducing environment.
Fe2O3 + 3 CO ® 2 Fe + 3 CO2
Meanwhile, the combustion gases (CO, CO2, N2, ..) which are formed cannot find suitable ways to exit the fine and frequently grained surfaces of the iron ores (0-8 mm) and therefore the furnace is in danger of being blocked. In order to prevent this problem, the ore must be agglomerated before being fed into the furnace, thereby increasing the hardness and gas permeability, which is called agglomeration.
In order to agglomerate the iron ore, pulverized coal and lime products are placed in it and burned at high temperatures (1200 - 1400 ° C). According to applied process, it is called sintering, briquetting or pelletizing. As a result of this process ore in 0-8 mm is transformed into hard particles in 2-2.5 cm size.
Lime products have important contribution to agglomeration process. Milled limestone (CaCO3), which is added to 10-12% ore with coal dust, reacts with the silicon and aluminum in the ore and calcined at approx 1200 - 1400 ° C and forms the calcium silicate - aluminum ferrite system.
This compound binds the fine particles of iron ore and imparts a certain hardness.
Another important role of limestone in the mixture is to keep the molar ratio of CaO: SiO2 at certain intervals (1.5-1.7 which is required for slag formation in high furnace
Some producers add 1 to 2% or more grinded quicklime (CaO) to the ore.
1. It is hydrated in mixing and ensures adherence of small grains (0.5-2 mm) ores and increases the permeability of the beds.
2. The heat released during hydration (270 kcal / kg CaO) provides energy economy by reducing the sintering temperature from 1400 ° C to 1000 ° C.
3. It increases sintering capacity and mechanical strength of sinter pellets.
The role of dolomite in the mixture is to adjust the slag composition that will occur in the blast furnace and to protect the furnace refractories.
Analysis of a typical sintered iron ore is as follows:
Slaked lime, which is used in pellet and briquette production up to 5% ratio, allows the grains of grains to stick and form.
Pig Iron production (blast furnace process)
The liquid iron is obtained by burning the ore given to the blast furnace after curing.
Fe2O3 + 3 CO ® 2 Fe + 3 CO2
FeO + CO ® Fe + CO2
Limestone is used to remove impurities (such as sulfur, silicon, aluminum, manganese) from ore or coke during the reduction of iron ore to iron in blast furnaces; The impurities in the ore generally have high melting temperatures (E.Ex Al2O3: 1730°C; lime: 2570°C.) and are therefore very difficult to separate at furnace temperatures. However, as a chance, the lime compounds of these impurities can be removed from iron by melting at temperatures as low as 700 - 1400 ° C.
The limestone reacts effectively with impurities by turning into lime at high temperatures in the kiln and removes them as a low-density slag (approx. 250 - 400 kg slag / t-iron).
CaCO3 ® CaO + CO2
CaO + FeS ® CaS (curuf) + FeO
CaO + SiO2 ® CaSiO3 (curuf)
Generally slag components
CaO - Al2O3 - SiO2 - MgO - S - Na2O
(%90) like this.
The fluidity of the slag should be high and the melting point should be low. For this, it is preferable to have a basic structure of slag. The limestone given to the blast furnace increases the fluidity of the slag compound (low viscosity) and It forms compounds at low temperatures with impurities.
When the lime dosage given according to type and amount of impurities in the ore, is choosen to be ensure the degree of basicity (CaO / SiO2) as more than1.1, a slag is obtained from basic structure with good properties (viscosity viscosity optimal: 1 - 5)
The amount of limestone given to the furnace depends on the purity of the ore, but usually it is between 160 and 200 kg per ton of iron. Blast furnace slag is used in Portland cement.production.
Where purer steel is required, secondary refining is usually required. Many secondary refining processes use lime to perform important functions, such as adjusting the temperature or chemistry of the steel, removing additional impurities, and preventing impurities from being sucked back. In addition, it can be used in combination with other materials such as florspar or alumina to form synthetic slag that is used as the lime to remove the quicklime, sulfur and phosphorus.
The extinguished lime (whether dry or juicy) has a number of applications in the manufacture of steel products. Widely used in wire drawing from steel rods or used to prevent sticking on cast iron molds
Lime is used to neutralize the acid-based waste pickling solution in which the iron salts are also precipitated. Lime bath is usually used to neutralize the pickling acid remaining in steel products. In addition, the steel product may be coated with lime to protect temporary corrosion. Slaked lime is used to neutralize the acid in the coke by-products.


Sibanthracite Group is ranked first in the production and export of UHG anthracite throughout the world and is the largest producer of metallurgical coal at the domestic level. Sibanthracite Group is one of the most dynamically developing coal companies in Russia. The coal production amounted to 6 million tonnes in 2014, and 24.1 million tonnes in 2018.
There is no doubt that the popularity of Russian coal is rising. A recent Reuters article details just how Russia’s recent strategic moves, like the Port Vera project by Dmitry Bosov from Sibanthracite Group, are pushing them past the competition to become the leader of coal exportation.
Russia has a distinct advantage over other European coal exporters. Its location enables access to ship to the Baltic Sea, Black Sea, and along with the European rail system. With transportation of coal being one of the critical drivers for overall cost, this helps Russian coal be priced more competitively. Russian coal costs less, due to lower sea and rail freight charges. The overall transport cost is considerably less than competitors like Colombia, the United States, and South Africa.
New environmental fuel regulations also place Russia at an even more significant advantage. IMO 2020, a new regulation, will increase sea freight costs further for coal exporters. With shorter sea distances, Russian coal will be even more cost-effective.
While coal consumption has declined slightly in the west, the Far East is importing record amounts. China and Japan’s imports increased by more than 14% last year. Currently, Russia trails behind Australia and Indonesia in coal exports, but that looks like it is changing rapidly.
Out of the top three world exporters of coal, the real competition is between Australia and Russia, as Indonesia primarily exports low-grade fuel. Australia’s shipments have slowed while Russia’s percentage gain has been growing considerably. Sibanthracite Group has been working to increase port capacity through the renovation of Port Vera in Cape Otkryty. This will greatly increase the ability of Russian coal companies to transport high-quality metallurgical coal to the Far East.
Because of Russia’s low costs and unmatched transportation abilities, it is only a matter of time before they are the world’s top producer and exporter of coal.
Dmitry Bosov’s Sibanthracite Group is ranked first in the production and export of UHG anthracite throughout the world and is the largest producer of metallurgical coal at the domestic level. Sibanthracite Group is one of the most dynamically developing coal companies in Russia. In 2018, it produced 24.1 million tonnes of coal and anthracite.


Australian lithium miner Anson Resources [ASX:ASN] announced final approval for its Western Strategy Resource expansion drilling program at its flagship Paradox Lithium Project in Utah, USA.
Anson can now go ahead with its re-entry drilling and sampling program at the Mineral Canyon Fed 1–3 well and Sunburst 1 well alongside a substantial increase to the Paradox Project’s existing JORC Mineral Resource.
Trading at around 19 cents apiece at the time of writing, ASN may have taken a 6% devaluation in the week, but it has climbed 58% in the past 52.
ASN is doing well for its sector, beating the lithium average by more than 61%, while the likes of Core Lithium [ASX:CXO] and Lake Resources [ASK:LKE] have moved down 20% and 69%, respectively, in the past year:
Anson Resources to begin Western Strategy drilling
The lithium miner now has all approvals needed for its Western Strategy Mineral Resource drilling program at its Paradox Lithium Project in the Paradox Basin in southeastern Utah.
Having paid a reclamation bond to the Utah State Treasurer of America’s Division of Oil, Gas and Mining, the final approval has been granted, and the Western Strategy drilling program can officially commence.
Western Strategy drilling will target the Mineral Canyon and Sunburst wells re-entry within the proposed area and is designed to convert the existing Inferred Resource and Exploration Target in the western region to Indicated and Inferred Resources.
If results are favourable, the re-entry programme could significantly expand the Paradox Project’s existing JORC Mineral Resource of 1.04 Mt of Lithium Carbonate Equivalent (LCE) and 5.27 Mt of Bromine.
Sampling Mineral Canyon well and Sunburst well brines will be tested for lithium (Li) and other minerals, including bromine (Br), iodine (I) and boron (B), from the Mississippian limestone units and select shallower clastic horizons.
Anson Resources stated:
‘Both wells are located less than 1,000m from known lithium-rich brines previously sampled in the “Big Flat” area during historic oil and gas exploration programs. All clastic zone and Mississippian horizons are continuous from those sampled during the successful initial Eastern Strategy drilling program.
Anson has defined a significant Exploration Target for the Western Strategy at the Paradox Project. This was recently upgraded for both the Mississippian Units and the Pennsylvanian Paradox Units, based on the exploration program proposed and recently completed drilling (ASX announcement, 25 January 2023).’
The exploration target for the Paradox Lithium Project’s Western Strategy consists of 2.10–2.56Bt of brine grading 108–200ppm Li and 2,000–3,000ppm Br.
According to Benchmark Minerals, lithium prices have dropped by almost 20% since January.
This is despite soaring sales for electric vehicles and comes to the surprise of many analysts who have been predicting a high trajectory for the critical mineral as clean energy strategies and initiatives take firmer hold.
As lithium prices moved into a tight period of correction, lithium explorers have taken a hit through investor valuations.
Compared to its peers, Anson has not been as badly hit. As the lithium developer establishes itself further across its projects in WA and the US, it will be interesting to see what happens next for the company.
Drilling boom Australia
The universe of booming drillers is making huge bull market-like gains in the face of recession fear, interest rate hikes and market volatility.
More of these booms are marked to happen for every single metal that can be found on the period table.
It’s been described as a ‘new golden age’ for junior explorers and investors who get in early.
Aussie mining is at its best right now, but if so many of them topped 2022, can they really do it again in 2023?
Our commodities expert James Cooper has found six ASX mining stocks that are heading to the top of the charts.

The future of Kenya’s largest mining company Base Titanium hangs in the balance due to depleting minerals and delays in approving new mines.
The company says resources at the Kwale South dune will run out in two years’ time while the government is yet to extend the boundary to incorporate some additional mineral resources.
The company says the boundary has proven ore deposit that can last the company for another 12 months.
For the last seven years Base Titanium has been mining titanium in Kwale County with an investment portfolio of more than 30 billion shillings in mining infrastructure.
Last year the company paid royalties to the Kenyan government amounting to 2.5billion shillings after earnings rose to 4.96 billion shillings in the year ended June 2019.
However, the future of these investments is now in limbo as the company faces backlash from local communities in its mining base of Kwale County, where local residents have accused the Australian firm of exploiting the region.
Base Titanium holds two prospecting licenses that cover an area of more than 80 square km according to the company’s books and the license is valid until May 2021.
The firm says it will exhaust the minerals in the current location by mid-2023 subject to an extension of its mining area beyond the Kwale south dunes.
Base Titanium’s external affairs General Manager Simon Wall says the mining tenure arrangements to extend the Kwale special mining lease are progressing with the state department of Mining.
The company which is a subsidiary of the Australian mining giant Base Resources Limited says it doesn’t not expect earnings to drop significantly this year due to good prices of rutile, ilmenite, zircon on the international market.

The mining industry in Indonesia is regulated by way of mining laws. The main regulation is Law 4/2009 on Coal and Mineral Mining, which is further implemented by various regulations and decrees issued by the central government, the Ministry of Energy and Mineral Resources (MEMR) and regional governments at the provincial and regency or municipal levels.
Mining Indonesia: The Industry in Perspective
Indonesia continues to be a significant player in the global mining sector specially production in coal, copper, gold, tin, bauxite, and nickel. Indonesia also one of the world’s largest exporters of thermal coal. There has been limited investment in mining in recent years, and particularly limited investment in greenfield projects.
After a decade, there is still a long way to go before Indonesia can fully realise its mining industry potential. It was hoped that the New Mining Law and its supporting framework of implementing regulations would provide investors with the necessary regulatory certainty to spur new investment and strengthen Indonesia’s position as a key player in the mining sector.
The most active regions for coal mining are: South Sumatra, Jambi, Riau, Central Kalimantan and East Kalimantan.
The most active regions for mineral mining are: Bangka Belitung Islands, West Kalimantan, Central Sulawesi, Southeast Sulawesi, Maluku and Papua.
Mining Regulatory Framework
The main regulation is Law 4/2009 on Coal and Mineral Mining, which revoked Law 11/1967 on the General Provisions of Mining, introduced a licensing system for mining business activities.
In the previous mining law, mining activities are conducted based on:
- Mining authority for domestic investment,
- Contract of Work (CoW) for foreign investment.
However, according to Law 4/2009, there are three types of mining permits:
- Mining permit (IUP),
- Small-scale mining permit (IPR),
- Special mining permit (IUPK).
To reflect the different stages of mining activity, IUPs and IUPKs are divided into:
- IUP exploration (IUPE) and IUP operation production (IUPOP)
- IUPK exploration and IUPK operation production (IUPKOP).
Unlike the licensing system, a CoW is a contract entered into by a foreign investor with the government as the basis for the investor to carry out mineral mining business activities. When Law 4/2009 came into force, all mining authorities had to be converted into IUPs, while CoWs are honoured until their expiration.
The MEMR, governors, regents and mayors, according to their respective authority, are authorised to issue IUPs, IUPKs and IPRs.
An IUP is granted for mining activities undertaken in a mining business permit area (WIUP), while an IUPK is granted for activities carried out in a special mining permit area (WIUPK).

The Ridges Iron Ore Project is situated in the Far North of Western Australia, 165 kilometres by road south of Wyndham adjacent to the Great Northern Highway. The resource is located along the top of a ridge over an area approximately 200m wide x 3km long. The iron ore outcrops at surface and the ore body thickness varies from 3-15m deep. The project had a confirmed mine life of four years based on a production rate of 1.5 Mt per annum of high grade direct shipping ore (DSO), with a high probability of increased production through future exploration success at Matsu and the beneficiation of lower grade ore at Ridges. KMG commenced shipping iron ore in July 2011 through its own private export facility located at Wyndham and placed the mine onto care and maintenance in February 2015 once the high grade DSO reserve was depleted. As of February 2015, KMG had exported approximately 6 million tonnes of iron ore from Ridges.
The Matsu project is a nearby satellite deposit to Ridges. Matsu is well advanced with mining leases and associated tenements having been granted in 2014. The Company is preparing submissions to obtain the necessary approvals to allow mining to commence subject to prevailing iron ore prices, market conditions and exchange rates.Previous

Indepth Knowledge of Stages in Coal Processing
Coal processing can be divided into three parts such as coal preparation, clean coal processing and moulded coal processing. Coal Preparation and Utilization include: coal properties and coal petrography; coal quality and characterization; surface chemistry of coal and minerals; crushing, grinding and liberation; coal screening and classification; dense medium and density separations; froth flotation and oil agglomeration; process control and optimization; flocculation and thickening; dewatering and thermal drying; briquetting and pelletizing; coal handling and storage; coal utilization and blending; waste disposal and pollution.mining equipment for sale Additional subjects covered by the journal include properties of coal/water and coal/oil slurries as well as the processing of oil shales and tarsands by physical and physiochemical methods.
Coal preparation according to different methods can be divided into physical preparation, physical and chemical preparation, chemical and microbial preparation and other coal preparation. Physical coal preparation is under the physical properties of coal and impurities (such as particle size, density, hardness, magnetic and electrical properties, etc.) on the difference of separation, the main methods of physical separation: Preparation of gravity, including jigs, heavy-medium coal preparation, coal preparation chute, shaking preparation, such as wind preparation. Electromagnetic election, using the electromagnetic properties of coal and impurities separation differences, this method is not in the actual production application of coal.
Chemical coal preparation takes advantage of chemical reaction to make a useful component of coal enrichment, remove impurities and harmful elements process.copper ore flotation machine Currently used in the laboratory method is chemical desulfurization. According to commonly used chemical reaction mechanism of different types and can be divided into alkali treatment, oxidation and solvent extraction. Microbial coal preparation is making use of some microbial autotrophic and heterotrophic microorganisms, directly or indirectly, to use its metabolites in the leaching of sulfur from coal to achieve the purpose of desulfurization.

However, different degrades of coal are used in different application with different requirements, and so Hongxing Machinery supply all kinds of coal mills to process coal ores like hard coal, woody lignite and lignite, anthracite coal and petroleum coke.


Portrait of the past: The McKinney Mine
The McKinney Mine
The McKinney Mine near Little Switzerland was once the largest feldspar mine in the world, according to the Little Switzerland Business Association. Feldspar, ground up, has been used as a hardening component in glass-making, a bonding agent in ceramics and an abrasive in household cleaner made by Bon Ami, which owned a mine adjacent to McKinney. The rugged terrain that became the center of production was the property of small landowners, one of whom, S.D. McKinney, leased property to Carolina Minerals Company in 1922, Robert Schabilion documents in "Down the Crabtree." The feldspar boom started when gem prospector William Dibbell scrubbed sorted feldspar at the Flat Rock mica mine near Penland and got an Ohio manufacturer interested in ceramic grade feldspar, geologist Alex Glover reveals. In time, mining companies dug tunnels descending 300 feet, creating caverns called stopes. The quality of the "spar" decreased and the danger of mining increased, Lowell Presnell writes in "Mines, Miners and Minerals," and the McKinney mine ceased operation in the 1950s. The Museum of N.C. Minerals is located at milepost 331 on the Blue Ridge Parkway. This Asheville Chamber of Commerce photo is courtesy of Jim Coman.

Judith Phiri, Business Reporter
THE Ministry of Mines and Mining Development has dispatched 11 teams of the Gold Mobilisation National Taskforce to the country’s eight mining provinces as it steps up efforts to boost gold deliveries to Fidelity Printers and Refineries (FPR) and achieve the US$12 billion target by 2023 in line with vision 2030.
The mobilisation team will educate miners on the environmental regulations, mining policies and practices and records keeping.
The taskforce will ensure that the Government set target of 60 tonnes gold deliveries to FPR is met compared to 32 tonnes last year.
In a circular to its members, the Zimbabwe Miners Federation (ZMF) said: “This memo serves to notify all miners that The Gold Mobilization Team (GMT) will be dispatched from Friday to all provinces and check for compliance issues.”
“Miners are therefore urged to be compliant with all mining legislative issues and that mine records are readily available for inspection purposes. One of the terms of reference for the GMT is for miners to account for all the gold extracted,” said ZMF chief executive officer (CEO) Mr Wellington Takavarasha.
Young Miners Foundation (YMF) CEO, Mr Payne Kupfuwa also urged young miners to comply and provide all the requisite records required by the taskforce when they visit their mines.
The national taskforce is a collaborative effort that involves the country’s security apparatus and the Ministry of Mines and Mining Development and its primary mandate is to make sure that all gold produced in the country is delivered to FPR.
Mines and Mining Development Minister Winston Chitando is on record stating that the US$12 billion mining industry target by 2023 was achievable as part of the broader macroeconomic roadmap towards achieving an upper middle-income economy by 2030.
In 2019, President Mnangagwa launched the US$12 billion mining industry roadmap where gold is expected to contribute US$4 billion, platinum US$3 billion while chrome, iron, steel, diamonds and coal will contribute US$1 billion each.
Lithium is expected to contribute US$500 million while other minerals contribute US$1,5 billion.


At the coalface
The competition is intensifying for Mongolia’s mineral riches, and if Ulan Bator has its way, China may be on the outside looking in. Six companies have been shortlisted for the rights to develop part of the Tavan Tolgoi mine, one of the largest undeveloped coal deposits in the world. As Mongolia’s largest trading partner, China should figure to have an advantage over the other bidders – including Luxembourg’s ArcelorMittal and Brazil’s Vale – but only one Chinese company made the cut.

Roy Hill is an iron ore mining project in the Chichester Range in the Pilbara region of Western Australia, located 115 kilometres north of Newman and 277 kilometres south of Port Hedland.
TracBASE was approached by Thiess Pty Ltd as soon as they were given the contract by head contractor Samsung C&T on the $10bn Roy Hill Project.
The job involved gathering as much information as possible from the fabrication and supply-chain for all materials required to construct the job. Initially TracBASE was built around the structural steel data extracted by the TracBASE team from various NavisWorks and Takraf models.
TracBASE was used to track all material onto the project – Structural Mechanical; Piping; Electrical; Instrumentation.
The Roy Hill site consisted of;
- 3 Crushing stations – each with a primary and secondary crusher
- 15 conveyor systems
- 1 fixed stacker
- 5 Course Ore Stockpile vaults
- 5 conveyors into the Wet Scrubbing Building
- 3 Dry Screen Building
- 3 Tertiary Crushing systems
- 5 Desands buildings
- 3 Thickeners
- 1 Fines Stacker
- 1 Course Stacker
- 1 Reclaimer
- 1 Flocculant system
- 1 Coagulant system
The majority of structural steel came from Thailand and comprised of 11 vessel shipments arriving at Port Hedland. The long journey from the Port to site was a slow process with some modules travelling at 30kph over the 320km journey to site
The mechanical components of the project came from all over the World with the bulk coming form Germany; Japan and the East coast of Australia.
After the initial data extraction from the models, TracBASE mobilised staff on site to manage the project. The amount of materials incoming would vary from a small truck right up to 30 trailers fully loaded.
All incoming material was checked by the logistics team, then barcoded and scanned with the location details and which laydown it was in. In total, there were 15 laydown areas across the project site that spanned 5 kilometres.
With the supply of project material spanning over 12 months, site engineers were able to log into TracBASE and see what material was on site. This allowed the Project Managers to give direction to the construction team to work on areas where more material was on site.
TracBASE was also used to track progress on the supply and installation of all the Instrumentation.

'Energy Basins' Give Boost to Uranium Search
11 June 2012 | With increased uranium demand - due to the projected growth in nuclear energy and dwindling supplies from secondary sources - new exploration models for uranium deposits are increasingly being debated.
To present new data and results of investigations in sedimentary basins, over 80 experts from 28 IAEA Member States gathered in Vienna from 29 May to 1 June in a Technical Meeting on the Origin of Sandstone Uranium Deposits: A Global Perspective.
“Large sedimentary basins which host accumulations oil and gas as well as coal deposits support the major energy requirement of the world. These basins are becoming targets for discovering new deposits of uranium associated with sandstones, which could significantly increase the availability of low-cost uranium,” explained Mr Harikrishnan Tulsidas, IAEA Nuclear Technology Specialist and Scientific Secretary of the meeting.
“In the meeting we were asked to consider recent advances to understand the origin of sandstone uranium deposits and to see how this knowledge can be useful in exploration and optimizing production, and to safely manage the mine wastes and remediation after the production closes in the area”, he said.
Sandstone uranium mineralization is the most abundant style that can be found in every continent. About a quarter of the world’s identified uranium resources are of this type and are distributed in over 550 deposits reported in some 40 countries. These resources currently contribute to a major share of the world production of uranium.
Origin of sandstone uranium deposits is closely related to the sources of uranium, the solutions that mobilize uranium, and the precipitating action of various agents. Hydrogen sulphide produced by bacteria, hydrocarbon fluids of oil-gas basins or reductants related to coal deposits have been proposed as agents responsible for a number of important sandstone uranium deposit. Several new discoveries of sandstone uranium deposits could be possible in many parts of the world.
At the meeting, a number of experts presented data on new approaches to exploration using geophysical techniques. Socio-economic and environmental aspects of developing such resources were also discussed.
“While the known sandstone uranium provinces of Kazakhstan, USA and Australia were discussed in detail, the meeting was successful in opening discussion on less known deposits and occurrences from Algeria, Argentina, Egypt, India, Jordan, Malawi, Paraguay and Tanzania”, said Mr Michel Cuney, Research Director, French National Centre for Scientific Research (CNRS), who chaired the meeting.
“Many new discoveries could be expected from these places as exploration campaigns are increasing with the involvement of a number of companies”, he added.
Uranium mining from sandstone deposits, due to its suitability for In Situ Leaching (ISL), is low-cost and could be used in production faster than some of the other deposit types. Sandstone uranium deposits could also be developed by conventional open-pit and underground mining methods if the ISL option is found to be unsuitable.
Many of the uranium projects, which have been launched recently or are expected to start soon, are based on sandstone deposits.
The IAEA provides information on the status of world uranium production and projections of uranium requirements. Member States with uranium production and/or nuclear power programmes use this information for their planning and policy making.

Thermodynamic Cradle-to-Cradle Assessment of the Earth's Mineral Resources
* Book: Thanatia: The Destiny of the Earth's Mineral Resources. A Thermodynamic Cradle-to-Cradle Assessment. By Antonio Valero Capilla and Alicia Valero Delgado. World Scientific, 2014
"Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.
This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment.
The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities."

Global mineral resource estimate of approximately 2.4 billion tonnes (99% in the measured category)
Thermal coal qualities suitable for export market, domestic power generation and for coal gasification
Location & Landholdings
CIC Energy’s coal resource is located in the Mmamabula Coalfields of southeastern Botswana, adjacent to the country’s main road and rail corridor which links the country’s capital, Gaborone, with its second largest city, Francistown.
Figure 1: Mmamabula locality map
The Mmamabula Coalfields form the western extension of South Africa’s Waterberg Coalfield, which contains approximately forty percent South Africa’s coal resources, along with Eskom’s 3,690 MW (net capacity) Matimba power station and Exxaro Resources Limited’s 19 million sales tonnes per annum Grootegeluk coal mine. Exxaro has also been contracted to supply a further 14 million tonnes per annum to Eskom’s 4,800 MW Medupi power station, now under construction.
The two prospecting licences, RL2009/1R (also referred to as the Central Block), and PL11/2004 (divided into the Eastern and Western Blocks) are 100% owned by CIC Energy subsidiaries. The total area for the two licences is 295.4 square kilometers (km2).
The Central Block is the site of the planned coal mine (Serorome Mine) envisaged to supply the Mmamabula Energy Project’s (“MEP”) 1,200 (net) MW power station. The anticipated capacity of this coal mine will be approximately 6.3 million metric run of mine tonnes per year, yielding 4.7 million metric sales tonnes per year.
Figure 2: Serorome Mine layout showing sufficient reserves to supply the Mmamabula Energy Project power station for 30 years plus more than a 20% reserve margin
The 1.3 million sales tonne per annum (mtpa) mine that will support the planned 300 (gross) MW Domestic Power Project (“DPP”) will be located in the Western Block (PL11/2004) and will utilize about one-third of this block as per the layout below.
Figure 3: Domestic Power Project (“DPP”) and related infrastructure
Geology, Exploration & Mineral Resources
Since commencement of exploration by CIC Energy and its predecessor, Coal Investment Corp., in mid-2005, up to twelve drill rigs have been active concurrently on CIC Energy’s Mmamabula Coal Field. In excess of 165,000 metres have been drilled in approximately 2,000 holes and the exploration drilling program is now largely complete.
In March 2011, CIC Energy announced a mineral resource estimate of approximately 2.4 billion tonnes as per Table 1.
Table 1 - Mmamabula In Situ Mineral Resource Estimate (D1 + M2 + D2 Upper Seams: Western, Central and Eastern Blocks)
(effective date: March 31, 2011)
Measured + Indicated (total)
Figure 4: Mmamabula In Situ Mineral Resource Estimate: 2.39 Bt (measured and indicated) and 3 Mt (inferred) at Mmamabula
The three coal-bearing areas defined within CIC Energy’s Mmamabula project area (Western, Central and Eastern Blocks) have drill hole spacings that are typically set at 500 metres (“m”) by 500 m or less.
Of the 2.4 billion tonnes of in situ coal at the Mmamabula Coal Field, work done by CIC Energy’s mining team indicates that the resource can potentially deliver an extractable tonnage of 1.5 billion tonnes (run of mine). This estimate is based on applying open cast mining methods over 30% of the area and bord and pillar with pillar extraction underground mining methods for the remainder of the resource.
Based on the analysis that has been performed, CIC Energy anticipates that the 1.5 billion tonnes of run of mine production could yield, after beneficiation, the following coal products: 112 Mt of thermal coal suitable for domestic on-site power generation and 900 Mt suitable for thermal export coal. This product mix is based on the typical coal qualities suited for these potential markets. The estimated qualities and quantities of these coal products are included in Figure 5 below.
Figure 5: Planned Coal Products from the Mmamabula Coal Field1
1The qualities and quantities of the coal products are estimates based upon the following: interpretation of geologic data obtained from drill holes and other sampling techniques, feasibility studies that derive estimates of cash operating costs based upon anticipated tonnage and grades of coal to be mined and processed, ground conditions, the configuration of the coal seams, expected recovery rates of coal from the seams, estimated sales revenues and operating costs from coal beneficiation activities, anticipated climatic conditions and other factors. No assurances can be given that the indicated qualities or quantities of coal will be produced. In particular, any change to the quality requirements or change to the mining methods as a result of production cost inputs would impact the coal product quantities.
Based on quality and thickness, three economic coal seams have been identified as the principal economic targets at CIC Energy’s Mmamabula Coal Field; these are the D1, D2 Upper and M2 seams. On the main Mmamabula PL11/2004 licence, the seams are relatively flat lying and in the areas of economic interest occur at depths of less than 140 m below surface. The D1, D2 Upper and M2 seams have average mineable thickness of approximately five, three and three metres, respectively.
Coal qualities across the Mmamabula licence area are mostly suitable for thermal power generation with raw coal calorific values (“CV”) for the major seams being approximately 20.3 megajoules per kilogram (“MJ/kg”) for the D1 seam and 22.6 MJ/kg for the M2 seam. Work to date by CIC Energy on the M2 seam, indicates that coal qualities generally increase from west to east, with the potential for higher-quality export coal in the M2 seam of the Western and Eastern Blocks.
Based on current mining cost parameters, approximately 30% of the Mmamabula coal resource could be extracted economically by open cut mining methods and underground bord and pillar mining methods using conventional continuous miners is being planned for the remaining 70%. Alternative mining methods (such as underground long wall extraction) that could further optimize resource utilization are also being investigated.
Washability (beneficiation) tests have shown that for a large portion of the resource, it is possible to beneficiate the coal to produce an export quality coal, as well as a lower quality coal suitable for on-site power generation and/or gasification. The relatively high sulphur contents, which average 1.8 %in the raw coal, could easily be reduced to less than 1% through beneficiation.
Table 2 is a summary of the total resource base showing tonnages, and thicknesses of the various seams in the different areas.

Qualified Person, Quality Assurance/Quality Control and Methodology
CIC Energy filed a NI 43-101 compliant Sixth Technical report, on SEDAR (www.sedar.com) on September 29, 2008. The report was entitled “CIC Energy Corp.: Mmamabula Energy Complex, Southeastern Botswana, Project No. J912, National Instrument 43-101 Sixth Technical Report.”
For the Sixth Technical Report, Mr. Grant van Heerden, Pr.Sci.Nat., of SRK Consulting (South Africa) (Pty) Limited (“SRK”) has reviewed, in principal, the processes and procedures used at the Mmamabula site in Botswana to generate geological information (drilling, logging and sampling) for input into the geological models. SRK concur with the procedures and methodologies used by the Company for geological model construction (physical models and coal quality models) as well as with the definition of coal resource blocks. Mr. van Heerden is a member of the South African Council for Natural Scientific Professions and is deemed a “Competent Person” under the South African SAMREC Code.
As discussed above, on August 14, 2009 CIC Energy issued a news release updating the mineral resource estimates in the Sixth Technical Report to account for the relinquishment of some of the original licence area, as part of the required process to renew the prospecting licences. Then on March 31, 2011 CIC Energy issued another news release announcing an update of this mineral resource estimate to 2.4 Bt.
Coal analyses were conducted by Witlab (Pty) Limited (“Witlab”) in Witbank, South Africa and M & L Inspectorate (Pty) Limited (“M & L”) in Middelburg, South Africa. Witlab and M & L are independent of CIC Energy and specialize in the sampling and analysis of coal. M & L has accreditation through the South African National Accreditation System (Facility Accreditation Number: T0313) and Witlab is in the process of obtaining such accreditation.

To bring limestone from a mine in India to a cement plant in Bangladesh, the longest conveyor belt was commissioned in 2005.
There are no intermediate drives or transfers between both end pulleys.
The belt is 35 km long, 800 mm wide, type St 2500.
A new record length belt was commissioned in 2015 at Sasol's Impumelelo project in South Africa. The conveyor length is 27 km, belt width 1200 mm, type St 2000 with 7+5 mm covers. The capacity is 2400 t/h at 6,5 m/s.


Roy Hill, Australia’s biggest mining construction project, includes a mine, a 344-kilometre railway to Port Hedland, and port facilities to export the iron ore at Port Hedland Harbour.
Monford completed the construction of an internal port road and drainage system. The road formed a key part of the support infrastructure within the Roy Hill mine and created safe access to and from the port area. The drainage works will ensure the road is not adversely affected by inclement weather conditions which could impact roader users.
Scope of work


- Traditional Coal Chutes causes clog
As for the traditional coal chute, the impact angle between the coal flow and the chute wall is too large, and the original kinetic energy is completely lost after collision. If the coal is of poor quality or high humidity, it causes plugging or buildup problems easily.
- Traditional Coal Chutes Generate dusts
1.The dust forms because the impact of coal flow and the chute wall when the coal is dry and fine.
2.The air inside the chute mixes the coal causes high pressure dust.
3.The coal flow speed increase when it fall from the top to the belt, it result in a lot of dusts.
- Smart Transfer Chute Reduces Clog
1. The curve of the design makes the coal move smoothly inside the chute.
2. No mater how the coal condition is, it will not build up clogs because there is no impact point.
3. The accurate calculation ensures the coal flow speed at the outlet is as same as the belt speed.
- Smart Transfer Chute Avoids dust
1. Because the coal flow is guided inside the chute, there is no massive air and coal mixing.
2. No high pressure dust forms
3. The coal slides to the belt instead of drop/fall onto the belt.
- Smart Transfer Chute Creates Better Working Environment
1. No Clogging --------by optimal design
2. No Dust--------by the design
3. Saving energy------by increased conveyor efficiency
4. Saving water --------by eliminating equipment cleaning , saving water 80%
5. Low capital invest-----by using less equipments and less infrastructures
6. Lower running cost-----by less maintenances of chute and conveyor
7. Less noise------by the design reducing noise up to 80%
8. Intelligent maintenance-----by using high-tech equipment to check and fix the chute liner regularly
