AMIS0165, Platinum concentrate, 4E = 39.69 g/t, Platreef, South Africa
Origin of Material: AMIS0165 is a commissioned CRM made from Mogalakwena North concentrate (PRNCP) concentrate material. The material was supplied by Anglo Platinum Limited.
Mineral and Chemical Composition: The Platreef is a Pt/Pd Ni/Cu ore from the northern limb of the Bushveld Complex in South Africa. Mineralization in the 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. Ore is finely ground and concentrated in a flotation process. Concentrate grades vary from 35 g/t to 110 g/t, and from this a PGM-rich nickel/copper matte is produced.
