What is claimed to be the first detailed kinetic analysis of flotation in a continuous cell for an Indian coal is reported. The effects of important process parameters on the flotation performance and kinetics have been described by developing suitable empirical models. Recoveries of non-ash and ash forming materials during flotation in a continuous cell are described adequately by first order kinetic equations.
