Platinumgroup Metal Ores An Overview Sciencedirect

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 pyroxenite ore and chromitite ore found in the Merensky Reef and Upper Group 2 Reef, respectively.
