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.

1. IntroductionThe platinum group elements (PGE: Ru, Rh, Pd, Os, Ir & Pt) are considered as critical metals (European Commission, 2014) and are highly valued for their high-tech applications. They are being recycled and intensely mined, but still deficits are experienced and expected in the coming years (European Commission, 2014).

The Platinum Group Metals (PGM) are located in the 5th and 6th rows of the transition metal section of the periodic table. Common characteristics include resistance to wear, oxidation, and corrosion, high melting points, and oxidation states of +2 to +4.

Since its discovery the Bushveld Complex in South Africa has attracted unprecedented interest owing to its ranking as the world’s largest layered intrusion, hosting the world’s largest resources of platinum-group elements (PGE) and Cr (Vermaak, 1995; Cawthorn, 1999a; Naldrett, 2004).
