Flotation is a process for separating finely ground valuable minerals from their associated gangue, or waste, or for separating valuable components one from the other. In froth flotation, frothing...
Probably more than any other aspect, xanthate entrenched froth flotations role in the utilization of the worlds natural mineral resources. Sulfide minerals are the largest of the groups of minerals floated. Today, more than a bil lion tons of sulfide ores are concentrated annually throughout the world with this technol ogy.
th The technology of froth flotation, invented in the early 20 century was first used for the concentration of sulfide minerals. Since then it has been applied for the processing of many nonsulfide ores as weIl, including oxides, carbonates, silicates, soluble minerals like halite and sylvite and energy minerals like coal and bitumen.
Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.

By implementing a low temperature plasma pretreatment step in the processing procedure for separating different sulfide mineral mixtures, it has been possible to improve the efficiency of froth flotation. Two powder mixtures consisting of pyrite/chalcopyrite and chalcopyrite/molybdenite were selectively oxidized in an Ar/O 2 microwave plasma.
6.2 Depression of Sulfide Minerals With Cyanide The depressing action of cyanide on pyrite during froth flotation is well known and is widely exploited on many flotation plants to selectively separate copper minerals from pyrite.
An improved process of froth flotation for non sulfide minerals arises when the collector employed is a combination of a fatty acid and an anionic perfluorosulfonate compound.
Removal of arsenopyrite from complex sulfide minerals by froth flotation NASA/ADS Arsenic is one of hazardous materials and a penalty element in metal concentrates and so metal concentrates containing arsenic of over 0.5% has been currently restricted in import and export trade.
