Origin of Material
This Merensky Concentrate material was supplied from the Waterval Smelter. The material originated from the the bushveld Complex.
Approximate Mineral and Chemical Composition
This material is predominantly or wholly derived from Merensky Reef which comprises components of feldspathic pyroxenite, pyroxenite and anorthosite. Peak PGE values are associated with a thin chromitite stringer. Mineralization in this Merensky Reef comprises 2-5% disseminated or net textured magmatic sulphides, predominantly pyrrhotite, pentlandite, chalcopyrite and pyrite. The PGE’s occur as micron-sized satellite grains around but rarely within the sulphides.
