The Bushveld Complex in South Africa hosts the world's largest resources of platinum-group elements (PGEs), which are mainly mined from three ore bodies, namely the Merensky Reef, the UG-2 chromitite, and the Platreef. In these ores, the PGEs are bimodally distributed, occurring both as discrete platinum-group minerals (PGMs) and …

11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

This chapter describes the production of concentrates containing the platinum-group metals (PGMs). South Africa is the largest primary producer of PGMs followed by Russia. South African ores typically contain 3–4 g/tonne of PGM ore, which becomes 100–200 g/tonne after flotation. There are two main types of ores namely; feldspathic ...
