• Leaching and recovery of platinum group metals from UG2

  Existing processes for the recovery of platinum group metals (PGM) from UG2 ores place stringent requirements with regard to chromite content upon feed material to the plant. An alternative hydrometallurgical process for which this is not an issue is proposed that involves reductive roasting of the ore followed by leaching with

  high operating cost, most platinum mine operations in South Africa have drifting towards mining and processing UG2 ore. Most mines process the UG2 ore from open pits and routinely suffers from low and erratic platinum group element (PGE) flotation recoveries. This is due to changes in mineralogy of the ore as a results of oxidation.
