Origin of Material
This is a low grade Platreef material from the Bushveld complex. The material was supplied by Anglo Platinum from Mogalakwena Mine.
Approximate Mineral and Chemical Composition
Platreef is a Pt/Pd/Ni/Cu ore. Mineralization in this Platreef comprises 2-5% disseminated or net textured magmatic sulphides, mainly pyrrhotite, pentlandite and chalcopyrite. The PGE’s occur as micron-sized satellite grains around but rarely within the sulphides.
