Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

The action of any flotation machine in successful operation seems quite simple, the mineral floating in preference to the gangue, giving rise to the phrase selective flotation. All that is necessary for the one type of machines is to place the mineral particles gently on the surface of a liquid so that they will not sink or, in the other ...
For more than a century now, flotation has been at the heart of the mineral processing industry. In this months SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.
Flotation is also used to remove impurities before hydrometallurgical treatment ie, carbon pre-flotation to purify low-sulfide and refractory ores for further processing. Flotation is considered to be the most cost-effective method of concentrating refined gold and is often used in conjunction with flotation
