Extraction of Platinum Group Metals

About 80% of the worlds' reserves for platinum group metals (PGMs) are in South Africa's Bushveld Igneous Complex. Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes …

The role of dithiophosphate as a co-collector in the flotation of a

In the present study the effect of adding sodium di-ethyldithiophosphate (DTP) to sodium isobutyl xanthate (SIBX) as a co-collector in the flotation of a platinum group mineral (PGM) ore was studied with a view to investigating whether there was any evidence of a synergistic beneficial effect resulting from the use of the mixture.

Potential Processing Routes for Recovery of Platinum Group

The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has conventionally been conducted through froth flotation, which typically achieves platinum recoveries of over 85%. The achieved successes of PGM concentration by flotation from the pristine sulfide ores are largely due to the occurrence of PGMs in close association with …
