Can coal washing be done more sustainably? - Metso Outotec

Coal washing, or coal beneficiation, is widely seen as an efficient method for getting the most from run-of-mine coal. On the other hand, it is a water-intensive process: typically, washing one ton of coal consumes about 45 m 3 liters of water. As environmental regulations tighten, mechanized mining increases impurities in run-of-mine coal and ...
