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.

Coarse-particle flotation applied to copper sulfide ores

conventional flotation cells process particle sizes in the ranges of 30 µm to 150 µm. In industrial operations, particles that are outside this range are generally reported in tailings, due to the inherent restrictions associated with the physical interactions that occur in the pulp and froth phases of conventional flotation equipment.

Common Questions About Froth Flotation Process Technology

Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.>
