2008-12-1 · Mineral flotation in mechanically agitated vessels (cells) involves complex interaction between bubbles, particles and the liquid phase. Ideally, just enough power input from the impeller is needed to so that the frequency of particle–bubble collision and attachment is maximised, while at the same time detachment events are minimised.

2021-8-15 · The ionic/polar part of the collector will interact with the ions present on the surface of the mineral, and it is adsorbed by chemical reaction or by physical adsorption. The organic end makes the surface hydrophobic, allowing it to be dragged by the gas bubbles and later separated in the flotation cell (Kelly and Spottiswood, 1982).
