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. Rate of floatability of individual size range particles varies with their ash percent and the maceral content present. Therefore, the flotation rate constant eventually becomes a function of maceral percentage of a coal particle. In the present paper, an attempt has been made by performing size-wise flotation tests using a sub-bituminous rank coal and flotation kinetics have been established based on maceral percentage reporting to concentrate at different time intervals of flotation. These results have been related to the kinetic behaviour of the process.
