Virtually all platinumgroup metals are recovered from copper or nickel sulfide minerals, which are concentrated by flotation separation. Smelting of the concentrate produces a matte that is leached of copper and nickel sulfides in an autoclave. The solid leach residue contains 15 to 20 percent platinumgroup metals.

Provided is a method involving flotation of a feed of platinum group metal ore material to prepare a platinum group metal concentrate during mineral processing operations. Prior to and/or during the flotation, a leadcontaining activator reagent and a xanthate collector reagent are added to the slurry and during the flotation, an oxygendeficient flotation gas, such as nitrogen gas, is used.

The platinumgroup metal content was more than twice that of a rougher concentrate, and the Al2O3 and CaO contents were significantly lower (see table 7). Because flotation concentrates would be subsequently treated by smeltingleaching or direct leaching techniques to recover platinumgroup metals, impurity contents are an important consideration.
