Principles of Froth Flotation | SpringerLink

The adhesive force with which a particle clings to the air-water interface is opposed by the gravitational drag due to its mass. For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the ...

Flotation Froth - an overview | ScienceDirect Topics

Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.
