  • PGM Ore Processing at Impala's UG-2 Concentrator

    However, largely, the PGM are finely disseminated, the average grain size being about 10 microns, so that grain size, liberation and association tend to dictate mineral floatability. Platinum group mineral grain size and association can be split into four categories: • Coarse PGM (roughly 5% of all PGE) • PGM associated with base metal and

  • Determining the PGM bearing mineral phase in the UG2 ore

    Jun 15, 2017· Fig. 2 shows the size distribution of material in the form of percentage of the mass of sample that remains on each sieve for the feed and after grinding periods of 10 and 30 min, plotted against the sieve size. Samples of about 100 g were used in all the three cases in order to perform the size analysis test.

    The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind.
