Studies on Separation of Macerals from Coal by Froth ...

In the past coal maceral separation have been carried out based on density difference e. g., sinkfloat analysis, density gradient centrifugation (DGC) techniques etc. These approaches are of limited success. Froth flotation is a physicochemical process separating particles on the basis of difference in surface properties in a vessel consisting of two distinct zones viz., pulp and froth zones.
