The Definitive Guide to Flotation Separation Fote Machinery
The flotation separation process mainly includes: (1) Grind the ore finely by the ball mill or rod mill to dissociate useful minerals from gangue minerals. (2) Separate the ore by the flotation machine. Adjust the ore pulp and add flotation reagents. (3) Do the flotation processing. (4) Filter, concentrate or dry the product .The ability of gravity separators to treat fine particles has been limited by the lack of particle inertia relative to the surface drag forces. However, particle inertia can be enhanced by the application of a centrifugal field.

Enhanced gravity separators: New alternatives for fine coal
Froth flotation is the most widely used technique for cleaning fine coal. This practice may change, however, with the development of enhanced gravity concentrators such as the Mozley Multi-Gravity separator (MGS). The MGS is a flowing-film concentrator that utilizes centrifugal forces to improve the separation of flotation-size particles.With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an Froth Flotation of Iron Ores
