Conventional flotation cells consist of a tank with an agitator designed 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. . The flotation process is used for the separation of a large range of sulfides,
It is a good electrical and thermal conductor. The main ores of copper are sulfides and oxides. Froth flotation tanks. . Soluble impurities of iron and nickel dissolve in the electrolyte, which has to be continually purified to prevent excessive
