Froth flotation is a physicochemical separation technique that exploits the difference in the surface wettability of mineral particles (Wills and Finch, 2016).From a heterogeneous mixture of solids, hydrophobic particles are made to attach to gas bubbles and subsequently carried to the froth phase and recovered as a froth product (typically …

Phenomena in the froth phase of flotation — A review

Abstract. The froth phase is one of the main components of froth flotation as it defines both the quality of the end product and overall efficiency. The performance of the froth depends on a number of sub-processes that interact in very complex ways, and it is a great research challenge to explicitly name the role of each of these sub-processes.

These collectors adsorb on the surface to render minerals such as chalcopyrite hydrophobic. Figure 1. Laboratory froth flotation machine.

Basic Principles & Variables Affecting Froth Flotation

The purpose of the oil in froth-flotation is (1) to form, together with the water and solid of the pulp and the gas introduced into the pulp, a froth; and (2), to aid in the selection of the particles of mineral of metallic, resinous or adamantine luster in the pulp from the gangue minerals. Not all oils will perform both of these functions ...
