Platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir), and osmium (Os) are called the platinum group metals (PGMs). As the "Vitamin of modern industry" and strategic materials vital for economic development,1 these elements have been widely used in a variety of applications, including electronic devices, catalytic converters, thermocouples, …

of the platinum group metals; therefore under suitable conditions a nickel matte can be produced that is low in copper and will contain the platinum group metals. At Brimsdown this operation is mainly carried out in a blast furnace, although six-ton Platinum Metals Rev., 1963, 7, (41, 137

All the necessary batch grinding tests on the platinum ore were done using the Wits laboratory scale mill, which is shown in Fig. 1 and its dimensions are shown in Table 1. The mill is fitted with 8 equally spaced lifters and is driven by a variable speed motor.

The six platinum group metals (PGMs) occur together in nature alongside nickel and copper. Mineable deposits of PGMs are very rare, with annual production amounting to around 400 tonnes, several orders of magnitude lower than many common metals. Due to their economic values and higher quantities, platinum and palladium are the most

The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each other, followed by final refining. Operations to achieve this can roughly be divided under three headings:

The raw material is heat-treated to produce a residue containing PGM in a state where cyanide can be leached, and then the residue is leached with cyanide using a solution containing cyanide so that the PGM is dissolved in the dissolved state. By producing a cyanide enriched leach solution containing PGM can be extracted from the source material
