The word 'selective' here refers to selectivity for one sulfide mineral over another. Selectivity for sulfides versus nonsulfides is generally excellent for sulfide collectors and is implicit. In groups (c) ... The use of dispersants has been sporadic in sulfide flotation.
The flotation testing program should start performing kinetic flotation tests to evaluate the effect of particle size on copper recovery, type of collector, frother, depressor, surface modifiers, optimum rougher flotation time, and pH.
Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10-cell "Sub-A" Flotation Machine and a 4-cell "Sub-A" Flotation machine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation.
To elucidate the mechanisms of sulfide mineral depression, the U.S. Bureau of Mines examined the depressant effect of hydrosulfide on flotation of copper sulfides, using electrochemical techniques and flotation tests. Hydrosulfide addition is commonly used to …
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.
Sulfide and non-sulfide minerals as well as native metals are recovered by froth flotation. This process is based on the ability of certain chemicals to modify the surface properties of the mineral(s). Other chemicals are used to generate the froth and still others are used to adjust the pH.

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".
This invention is directed to a method of beneficiating a mineral sulfide-containing material or a metallic species of gold, silver, copper, palladium, platinum, iridium, osmium, rhodium, or ruthenium by froth flotation in the presence of a collector as well as a collector for beneficiation of sulfide minerals, precipitates, or metallic species.
