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. [9]
