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.

Mineral processing

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particlese bound to the surface of the bubbles.
