working principle of coal washing plant

Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water mechanical techniques and relies on gravity and the difference of density between coal and it s impurities which are usually more densely packed due to the fact that
