Froth flotation - Wikipedia

Froth flotation is a process for selectively separating 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. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

Principles of Froth Flotation SpringerLink

If a particle is to be held in a mineralised froth, it must be ground to a fineness at which downward pull of gravity is insufficient to overcome its adhesion to an air-water interface. The usual commercial separation entails the lifting of a heavy metal sulphide away from a relatively light gangue by the agency of air bubbles rising through the pulp.
