In agreement with the PGE distribution, the following platinum-group minerals (PGM) have been found: laurite ((Ru,Os)S 2), erlichmanite ((Os,Ru)S 2), irarsite (IrAsS), vysotskite ((Pd,Ni)S), braggite or cooperite ((Pt,Pd,Ni)S) and Pd-telluride. The PGM form small grains, less than 10 μm across, and occur associated with base metal sulphides ...

The most common spheres larger than 300 µm do not, in fact, contain FeNi metal cores, but instead contain a micrometre-sized nugget composed almost entirely of platinum group elements.
Platinum group metals are also components of many autocatalysts, converting car exhaust gases in to less harmful substance. And our fascination with platinum as a rare and robust metal continues. The term 'platinum blond' came about in the 1930's when actresses with platinum jewellery were the stars of newly invented talking pictures.

These localities access the Platreef of the northern Bushveld Complex. Platinum-group element enrichment trends in the BMS are similar in the Overysel and Sandsloot samples, although the overall PGE concentrations in the Overysel BMS are lower than those in the Sandsloot BMS.
The platinum-group minerals in a drill core taken through the middle group of chromitite layers in the Critical Zone at Marikana in the western Bushveld Complex were found to consist mainly of laurite as inclusions in chromite grains.
The most common spheres larger than 300 µm do not, in fact, contain FeNi metal cores, but instead contain a micrometre-sized nugget composed almost entirely of platinum group elements.
The platinum-group minerals containing Pt, Pd, and Rh are concentrated in the intercumulus silicates and frequently associated with base-metal sulphides. Up to about 20% of all platinum-group minerals in the investigated chromitite layers contain sub stantial amounts of As.

Platinum group metals (PGMs), such as platinum (Pt), palladium (Pd), and rhodium (Rh), are of increasing concern due to rising anthropogenic input to aquatic systems. In this study, PGMs' effects on bioaccumulation and histopathological changes were investigated using Orconectes virilis, a native Hudson River crayfish, as a model. Organisms were exposed to varying concentrations of water ...

They should be read in conjunction with the December issue of this Journal, which reports on the ferroalloy industry where there are similar power increases. Where the supply of chromite is of concern, it is obvious that from the BIC a direction of maximum recovery of ...
Platinum-group elements have been used to identify the onset of sulfide saturation in magmas in preference to Au and Cu for two reasons: first, their partition coefficients into immiscible sulfide melts are at least one or two orders of magnitude higher than those of Au and Cu, respectively, making them more sensitive indicators of sulfide ...
The Journal of The South African Institute of Mining and Metallurgy AUGUST 2004 423 Introduction South Africa hosts more than 80 per cent of the world's reserves of platinum group metals (PGM). Recent reviews of the South African PGM industry focused on smelting1, general extractive metallurgy2 and .
Abstract. Concentration patterns of platinum-group elements (PGE) in the Lower, Critical and Main Zones of the Bushveld Complex are modelled by a process of metal collection by segregating sulphide melt followed by fractional crystallization of monosulphide solid solution (mss).
