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.

IX. FROTH FLOTATION

2012-8-10  IX. FROTH FLOTATION Froth flotation is a process used to separate minerals, suspended in liquids, by selectively attaching them to gas bubbles. Hence, in flotation we have a three-phase system. The separation principle is based on the lack of affinity of the mineral surface towards water, a property denoted by hydrophobicity.
