complete water circulation and gives a high recovery of platinum group metals and non-ferrous metals into rich concentrates. These are then suitable for refining.In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore,
