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.

A Sustainable Alternative to Froth Flotation

• Froth Flotation is one of the industry's standard ways of concentrating low grade, fine particle sized minerals. • This process is done by using water as a medium and manipulating the particles surface chemistries into being either hydrophobic or hydrophilic then using air bubbles to separate the hydrophobic particles.
