Froth Flotation - an overview | ScienceDirect Topics
Small particles of this type of material will readily cling to small air bubbles and may be raised to a froth in a flotation cell. The specific reduction in energy, WSA, from particle adhesion to, rather than release from a bubble by interaction of the three relevant interfaces is given by Eq. 13.1 .
