Froth flotation

Froth flotation

Froth flotation is a process for selectively separating of 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.

Froth Flotation Method This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the nonwettability of the metal part of the ore and allows it to form a froth.

Oct 24, 2021· Froth flotation is a widely used process for the beneficiation of complex sulphide ores. Thiol collectors (mostly xanthates) are usually effective collectors for sulphide minerals but may have a low selectivity between different sulphide minerals when associated in complex sulphide ores.

copper extraction and purification chemguide

Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining. The concentration of the solution should stay the same.

Copper extraction

Copper extraction

These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits. Supergene ores rich in sulfides may be concentrated using froth flotation.
