Unit 3 Reading: Mining and Mining Impacts Student Materials

Additionally, if a tailing pond dries out, the metals may be transported as dust on the wind and thus have the potential to be inhaled by nearby residents. Problems of a leaky tailings pile are especially problematic because sulfide minerals, often found in association with metal ores, may occur in high concentrations within the tailings.

From ore to steel – ArcelorMittal

Finegrained iron ore is processed into coarsegrained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made.
