Froth flotation

HistoryFroth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as quot;the single most important operation used for the recovery and upgrading of sulfide oresquot;. The development of froth flotation has improved the recovery of valu

Basic Principles amp; Variables Affecting Froth Flotation

The purpose of the oil in frothflotation is (1) to form, together with the water and solid of the pulp and the gas introduced into the pulp, a froth; and (2), to aid in the selection of the particles of mineral of metallic, resinous or adamantine luster in the pulp from the gangue minerals. Not all oils will perform both of these functions with all ores in all processes.
