Flotation concentration is effected by causing the selective attachment of a froth to certain minerals in a finely ground ore and agitated with water and frothing reagents. The froth, by its buoyant effect, causes the attached mineral particles to float, whereas the associated gangue minerals comprising the ore will sink.
