Kinetics of Coal Flotation 911metallurgist.com

Because most sulfurbearing and ashforming minerals are finely disseminated in the coal matrix, raw coal must be ground to a fine size in order to liberate and remove them from coal to an acceptable level. Froth flotation is considered to be one of the effective physical cleaning technologies available to separate fine mineral particles from coal.

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.
