Coal Beneficiation - an overview ScienceDirect Topics

2.4.1.1 Wet beneficiation/coal washing. Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the ...
