Minerals are mined either underground or through surface methods like open-pit mining. The mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth.
The mining industry consumes enormous energy for the operation of a mine. Major energy sources include fuel oil, electricity (purchased and produced on-site), coal, and natural gas. The energy-intensive nature of mining is evident by the recovery ratio of the various materials being mined. Coal, with an average recovery ratio of 82%, requires the mining of 1.2 tons of material to recover 1 ton of coal. Industrial minerals have an average recovery ratio of 90%, while metals have an average recovery ratio of 4.5%. Thus, to recover 1 ton of metal, 22 tons of material will need to be mined.
