At present, flotation is mainly used to treat copper sulfide and recover platinum group minerals together with copper and nickel sulfide. The separation effect of platinum group metal minerals is related to many factors, such as grinding fineness, medium acidity, reagent type and dosage, process arrangement and so …

Flotation was used for the first time to produce a sulphide platinum concentrate in 1926, at Potgietersrus. 28 The weakening of the platinum price in the early 1930s led to widespread closures and amalgamations, resulting in the formation of a single dominant company, Rustenburg Platinum Mines, in …

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.

The ore obtained from the operations undergoes crushing and concentration at the processing plants located at the mines. Ore is stored in a 3,175t silo before being fed to a SAG mill. Oversize is passed to a ball mill while undersize is cycled to flash flotation circuits. The float product is thickened, the concentrate containing 1,700g/t PGM.
