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.

The effect of particle size distribution on froth

Aug 31, 2017 Particle size distribution effects on froth stability quantified using air recovery. • A steady-state flotation system is developed to focus on particle size effects. • Fine particles result in higher air recoveries, but only at high air rates. • Changes in particle size require different air rates to maximise mineral recovery.
