s in mineral flotation and separation processes
Abstract. flotation is a process used worldwide to separate metallic and nonmetallic minerals from extracted ore. It is probably the single most important operation used in the mining industry in the world today. In the United States, for example, over one-third of the mineral concentrates produced are obtained using flotation [I].

Flotation in Water and Used Water Purification | SpringerLink
Flotation is one of the most important water treatment technologies having a broad variety of applications. Flotation is a unit operation for the separation of discrete particles from a continuous liquid phase. Similarly to sedimentation, this process uses the difference in density between particle and liquid phase and hence gravity as driving ...

Flotation Principles
Flotation Principles. Flotation, in its latest phase, is a process of concentrating ores by frothing. When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed. This froth, rising to the surface of the liquid mixture, is laden with sulphides or other ...
