When you plan a new mine or investment, our worldwide team of multidisciplinary specialists can provide a comprehensive, integrated approach to your viability studies (including scoping, feasibility and prefeasibility), due diligence reviews, economic evaluations, and risk assessments.
Safety and environmental control of mining activity remain key drivers, but expectations of sustainable development require the provision of electricity, water, healthcare and education to the local communities where mining operations are based. Companies are also more exposed to Political Risks and K&R activity than had previously been the case.
Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium. An important sulfide mineral common in waste rock is pyrite, iron sulfide. When pyrite is exposed to air and water, it undergoes a chemical reaction called ...
Safe carriage of Iron ore & other iron concentrates in bulk Iron ore is used for the production of metallic iron in steel-making. Although some 45 countries export natural iron ore resources, seven countries provide 75% of the total exported. The two largest exporters are Brazil and Australia, with about 33% of total world exports each.
Mining water use is water used for the extraction of minerals that may be in the form of solids, such as coal, iron, sand, and gravel; liquids, such as crude petroleum; and gases, such as natural gas. The category includes quarrying, milling of mined materials, injection of water for secondary oil recovery or for unconventional oil and gas ...

Globally, India is ranked as one of the leading producers of valuable minerals such as chromite, iron ore, coal and bauxite. The mining sector in India is highly regulated and the legal framework has undergone significant changes in the past three years, the result of which is a more transparent and efficient regime.
Lead and Mercury Emissions from Mining. Global releases of lead from smelting and refining nonferrous metals (e.g. gold, lead, zinc, copper) total over 28,000 metric tons/year. 1 Global releases of mercury from smelting and refining nonferrous metals total 710 metric tons/year – .
Mar 13, 2011· The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation. These occur in varying combinations depending on the mine or quarry, its depth, the composition of the ore .
There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.
Because of the existing hazards of mining as an activity and the complexity of mining machinery and equipment and the associated systems, procedures and methods, it is not possible to be naturally safe. Regardless of how well the machinery or methods are designed, there will always be potential for serious accidents.

Mining of Iron Ores. satyendra; March 14, 2014; 1 Comment ; Hematite, Iron ore, mines, mining, Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.
Smarter steels depend on high-quality raw materials. As one of the world's leading producers of iron ore, we supply nearly half of our own iron ore needs and provide the types of coal that are essential to steelmaking. Our mining assets provide supply security and quality for our own operations, and a source of high-value raw materials for our customers.
Sulfide mining, unfortunately, poses several significant environmental risks. The most significant one is the threat to water quality. When sulfide ores are exposed to air and water, the result is sulfuric acid, which causes the leaching of potentially toxic heavy metals and the release of sulfates that contribute to the methylation of mercury.
For example, in India, in the Sukinda mining area, around 7.6 metric tons of solid wastes have been generated in the form of rejected minerals, overburden material and waste rock, and subgrade ore that have caused environmental degradation, mainly creating lowering of the water table as well as deterioration of surface and groundwater quality ...
NEW DELHI: There will be no iron ore scarcity in the country post March 2020 as about 200 MTPA mine capacity will still be operational and auctioned iron ore blocks will start adding to the production, an industry body has said. According to Mines and Minerals (Development and Regulation) Act, licences of mines expiring will not be renewed and the mines will be allotted on the basis of ...
The environmental consequences of mining Iron Mountain became apparent only a few years after the start of open mining in 1896. Fish kills in 1902 in the Sacramento River, near the city of Redding, were the first documented effects, and shortly thereafter, several private lawsuits and an injunction from the U.S. Forest Reserve (precursor to the Forest Service) were served against Mountain ...
