Background. Occupational and environmental exposure to heavy metals, silica, and asbestos can occur during mining and milling operations. The smelting process (extracting the metal from the ore) is associated with the highest exposures and environmental releases.
In 2018, our mines and strategic contracts produced million tonnes of iron ore, we also produced million tonnes of coking coal. Our mining operations ArcelorMittal has both iron ore and metallurgical coal reserves and is among the largest iron ore producers in the world.

For that reason, hematite ore is important for many mining Australia's Magnetite Network explains, "[d]irect shipping ores, when mined, typically have iron (Fe) content of between ...
mining engineer may also be involved with the closure and reclamation of the mine property,although he or she may share those duties with those in the environmental ﬁelds. The ﬁelds of processing,reﬁning,and fabricating are assigned to metallurgy,although there is often some overlap in the mineral processing area with mining engineering.

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.
The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer process, bauxite is mixed with caustic soda, or sodium hydroxide, and heated under pressure. The sodium hydroxide dissolves the aluminum oxide, forming sodium .
