average energy consumption of key equipment used in coal, metals, and mineral mining. In absence of energy data on many mined commodities in the U.S., the E&E Profile benchmarks energy consumption for eight mined commodities, collectively responsible for approximately 78% of the energy used in the U.S. mining industry.
Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory low-cost method for recovering a fine, low ash, clean coal product at a profit.
