We obtained the material used in the experimental investigation from Nkomati mine, situated in the Mpumalanga province of South Africa. Nkomati Mine processes nickel (Ni) from a pentlandite ore. We collected the sample material (−20 mm) as a belt cut from the secondary crushers during normal operation.

The dominant sulphide minerals are pyrrhotite, pentlandite and chalcopyrite. Cobalt is mostly in solid solution in the pentlandite, and the platinum group metals (PGMs) occur as separate minerals, with merenskyite being dominant. The current mined chromite is contained within the Massive Chromitite Unit (MCHR) in the open-pit area.

Polyhedral clusters in solids. Electronic structure of pentlandite
The pentlandite structures are transition-metal sulfides that contain distinguishable metal atom cubes and exist only for certain combinations of the Fe group elements, Co9S8 being the only known binary phase. In this paper, we assemble the structure from the naked cube cluster after demonstrating the inadequacies of a ligand field analysis in rationalizing its physical properties. …
