Flotation Collectors - Mineral Processing Metallurgy

What is a Flotation Collector. For industrial sulfide mineral flotation, the xanthates and dithiophosphates are the major classes of Flotation Collectors compounds used, where M+ is either Na+ or K+, and R is a relatively short hydrocarbon chain typically containing two to five carbon atoms. The solubility, pH application range, physical state ...

Platinum - Palladium Flotation

A flotation method using mercaptobenzothiazole collector in an acid circuit was devised for preparing a platinum-palladium concentrate from Stillwater complex gabbro (Montana). Bench-scale experiments showed that rougher flotation recovered 91 pct of the platinum and 88 pct of the palladium in a concentrate assaying 2.6 oz/ton Pt and 8.8 oz/ton Pd.

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. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le
