Froth flotation is a widely used, inexpensive process for commercial separation of minerals from gangue and minerals from each other. Extensive research has demonstrated that electrochemistry governs the flotation of sulfide minerals. Flotation often is adversely affected by uncontrolled oxidation, which also is an electrochemical process.
