The kinetics of Fast Flotation using the Reflux Flotation Cell

1. Introduction. The firstorder kinetic model is commonly used to describe the flotation process (Ahmed and Jameson, 1985, Sutherland, 1948).For a given recovery, higher flotation kinetic rate constants lead to the need for a shorter residence time of the slurry in the flotation cell, thus offering the potential for reducing the volume capacity of the flotation cell.
