    Such platinum concentrates are then refined. Complex sulfide platinum ores are concentrated by flotation, with subsequent multioperation pyrometallurgical, electrochemical, and chemical treatment. The main countries producing platinum ore are the USSR, the Republic of South Africa, and Canada. The world reserves of platinum group metals (excluding the USSR) were estimated at about 7,000 tons in 1972

    Our investigations involved flotation concentrates of low-sulfide platinum-bearing chrome ores from South Africa. The ore had the compositions shown in the Table. An X-ray microscopy study of the phase composition of the flotation concentrate showed that nickel is present as pentlandite and copper as chalcopyrite. Iron is present in these minerals and is also present as pyrrhotite and in rock-forming

    Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors.
