Theics of Fast Flotation using the Reflux Flotation Cell

1. Introduction. The first orderic modelmonly used to describe the flotation process Ahmed and Jameson, 1985, Sutherland, 1948.For a given recovery, higher flotationic 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.
