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 …

Pentlandite is a mineral consisting mainly of iron-nickel sulfide, in which the ratio of nickel to iron is usually close to 1:1. Its chemical formula is written as (Fe,Ni) 9 S 8.It also contains minor proportions of cobalt.It has a yellowish bronze color. It was named after the Irish scientist Joseph Barclay Pentland (1797-1873), who first noted the mineral.

Pentlandite and chalcopyrite recoveries obtained from this ore at pH 10 are shown as a function of time in Fig. 7, Fig. 8, respectively. In sharp contrast to the case with the Sudbury ore, the pentlandite in this complex sulfide ore is completely depressed in the presence of lime while it reaches high levels of recovery in the soda ash system.
