pgm ore grinding parameters feed size and output size

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
