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.

May 26, 2016· The technology aims to improve the recovery of iron ore still contained in wastes or low grade ROM making it possible to obtain iron ore concentrate with 68 per cent iron.
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 KR activity than had previously been the case.
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 .

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 ...
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.
What Possible Water Hazards Are Associated With Mining Iron Ore. The largest physical disturbances at a mine site are the actual mine workings such as open pits and the associated waste rock disposal areas mining facilities such as offices shops and mills which occupy a small part of the disturbed area are usually salvaged or demolished when the mine is closed
Safe carriage of Iron ore other iron concentrates in bulk Iron ore is used for the production of metallic iron in steelmaking. 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 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.
Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cuttingedge technology, iron ore is processed and then sold to steel companies. The iron ore produced by Vale can be found in houses, cars and appliances.
