Froth flotation - Wikipedia

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Basic Principles & Variables Affecting Froth Flotation

In the agitation-froth process, it is, in general, more economical to attain enhanced bubble precipitation by greater intensity and duration of agitation than by heating the pulp, and in bubble-column processes difficulties in dispersion of the oil are surmounted by adding the oil to the grinding mills, or using an oil easy to disperse.

Flotation - an overview | ScienceDirect Topics

Main Features of Flotation and the Froth Flotation Process. Flotation is a process of separation and concentration of one kind of particulate particles from another by their selective attachment onto the fluid-liquid interfaces. Froth flotation and film (skin) flotation are the best examples of flotation taking place on the gas–liquid interface.
