The Journal of The South African Institute of Mining and Metallurgy JULY 2004 323 Introduction Existing processes for the recovery of platinum group metals (PGM) from UG2 ores place stringent requirements with regard to chromite content (about per cent) upon feed material to the plant. The conventional process sequence involves:
The high silver content, of approximately 100 oz/ton, makes lead cake a potentially valuable product. However, bismuth, even at levels of %, frequently limits the marketability of this material as lead smelter feed. In this and other systems, the selective removal of bismuth from such residues is of considerable interest.
