Tailings Wikipedia

Coal refuse (also described as coal waste, coal tailings, waste material, culm, boney, or gob) is the material left over from coal mining, usually as tailings piles or spoil tips.For every tonne of hard coal generated by mining, 400 kilograms of waste material remains, which includes some lost coal that is partially economically recoverable. Coal refuse is distinct from the byproducts of

Reducing the environmental impact of coal-washing practice

All Australian coal for export is washed — that is, the low-grade high-ash material is separated out and disposed of at the washery site. The coarse rejects are generally placed in embankments and the tailings are pumped into settling ponds. These methods of waste disposal can create environmental problems. In addition, they represent a significant energy loss, because about one-third of the
