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., sink-float analysis, density gradient centrifugation (DGC) techniques etc. These approaches are of limited success. Froth flotation is a physico-chemical process separating particles on the basis of difference in surface properties in a vessel consisting of two distinct zones viz., pulp and froth zones.
