Iron Ore Concentrating

Concentration of Ore

Sulphurized ore: These contain sulphides of metal like iron, and lead. Examples: FeS 2 (Iron pyrites), PbS (Galena), HgS (Cinnabar) etc. ... Thus, by concentrating ore from such impurities, we can actually extract and refine metals. Various physical and chemical processes are employed to concentrate or separate ore from the gangue matrix.

Sulfur oxide is volatile and evaporates off ...

Mining

In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking.
