01/01/2008· Mining is designed to first liberate the coal from the host clastic rock and beneficiation to liberate higher grade coal and discard stone and poorer quality coal through a process of comminution, density separation, and flotation that is controlled by particle size and surface chemistry.

Appendix E: Coal Mining and Processing Methods Coal

Longwall mining additionally requires large coal reserves to justify the capital cost of longwall equipment. As surface mining in the Powder River and Rocky Mountain Basins proceeds, it is likely that the stripping ratios (overburden to coal) will exceed an economic limit. If this coal is to be mined at reasonably high recovery rates, it

Coal Mining and Production IFC

Coal beneficiation is based on wet physical processes such as gravity separa-tion and flotation. Beneficiation produces two waste streams: fine materials that are discharged as a slurry to a tailings impoundment, and coarse material (typically greater than 0.5 millimeters) that is hauled away as a solid waste. Waste Characteristics The main impacts of surface mining are, in gen-eral, massive

4 Coal Mining and Processing Coal: Research and

As shallower coal is depleted and seams with greater amounts of overburden 6 are mined, surface mining will become more expensive because stripping ratios 7 will increase and multiple benches 8 will be needed. This will increase the number of unit operations and the associated cost.
