WO2005031013A1 Platinum group metal extraction by ore

A process for extraction of platinum group metals (PGM) includes smelting PGM concentrate to provide PGM-containing matte, spinel-rich slag and oxide-rich slag. The matte is enriched with regard to PGM in a conversion step by selective oxidation of undesired constituents thereof. The process includes, after the smelting and prior to the conversion, separating the matte and the spinel-rich slag
