An analysis of medium losses in coal washing plants ...

2006-9-1  Adhesion to coal and the losses in the magnetic separator are the two main routes through which magnetite gets lost in a coal washing plant. In general, magnetic separators seem to contribute 20–40% of this loss, though this proportion will fall where adhesion losses are abnormally high, for example, with porous ores.
