Froth Floation | Hoffman & Lamson Solutions

Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

FLOTATION

"Flotation" is a generic term for a number of processes known as "adsorptive bubble techniques", Lemlich (1972); these are classified into foaming and nonfoaming separation methods. Foaming methods require the addition of surfactants to generate a relatively stable foam or froth which then acts as a carrier fluid during particle removal.
