Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling hydrophobic or have an affinity for water hydrophilic. Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral usually but not exclusively sulfide minerals up to be recovered.
