Minerals

Apr 23, 2021Froth flotation is the most economical method to separate minerals in ores. However, the complexity of new ore bodies requires fine grinding to liberate valuable minerals, which produces particles with sizes too fine for an efficient mineral flotation and separation. In addition, fine grinding has produced undesirable effects, where gangue

Froth Flotation

Froth flotation for separating discrete mineral particles from gangue was developed in the early 1900s and depends upon differences in the surface chemistry of the mineral species involved. We have studied not only the flotation of sulfides, gold ores, iron ores, coal, oil shale, and many other nonmetallics, but also soluble salts, oxides, and

Seven Common Froth Flotation Processes

Oct 18, 2019Froth flotation process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. The froth flotation process is to grind the mineral to the floating requirement, adjust the pulp concentration and add the flotation reagents, then inflate the air to make the mineralized froth separate.
