Froth flotation

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.

Froth Flotation Process Mineral Processing amp; Metallurgy

FROTH FLOTATION So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined. The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.

Mechanical flotation Lenntech

In treating oily water from oil refineries, the separation of oil by mechanical flotation is called froth flotation. It is achieved by adding an organic coagulant or demulsifying agent. Flotation units are constructed with three or four cells in series. Froth flotation by injection of air may also be used for the separation of surfactants.
