2019-12-12 recoveries from oxidized ore. Recently, several researchers have investigated different methods to improve flotation recoveries of PGEs from the oxidized PGM ores, including ore pretreatment with mineral acids before flotation and sulphidization followed by xanthate flotation. Pretreatment with sulphuric acid marginally improved

2016-9-25 Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. While the recoveries of the sulfide minerals are considered satisfactory, using modern flotation ...

Flotation of Gold Ores also for beneficiation and separation of difficult-to-treat (refractory) gold ores. Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration, flotation remains the most cost-effective bene-ficiation method.
