    Investigations into the Recovery of Platinum Group ...

    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, located in the northern limb of the

    Platinum-Group Element - an overview ScienceDirect Topics

    Platinum-group elements occur mainly in or near sulphide minerals in an ore deposit. They are typically dissolved in pentlandite [(Ni,Fe) 9 S 8], or present as distinct mineral grains, for example, as braggite [(Pt,Pd)S].The minerals containing platinum-group elements are often attached to or occluded by grains of pentlandite, pyrrhotite [Fe 8 S 9] and chalcopyrite [CuFeS 2].

    Virtually all platinum-group 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 platinum-group metals.
