Ore Processing and Refining

1. Comminution: Crushing and grinding the ore to liberate PGM grains.
2. Froth flotation: Separating sulfide minerals containing PGMs from gangue.
3. Smelting: Concentrate is melted in furnaces, producing a PGM-rich matte (containing iron, nickel, copper, and PGMs).
4. Converting and leaching: Removing base metals via oxidation and acid leaching.
5. Aqua regia dissolution: The remaining PGM concentrate is dissolved in aqua regia. Platinum goes into solution as H₂PtCl₆ (chloroplatinic acid).
6. Selective precipitation: Adding ammonium chloride precipitates ammonium hexachloroplatinate, which is then calcined to produce pure platinum sponge.
7. Melting and casting: Sponge is melted in induction furnaces (under inert gas or vacuum) and cast into ingots, bars, or grains.

Mining Methods

• Underground mining: The Merensky Reef and UG2 Reef in South Africa are primary sources. Miners use conventional drilling and blasting or mechanized room-and-pillar methods.
• Open-pit mining: Used where ore is close to surface (e.g., Russia’s Norilsk region).
• Placer mining: Rare today, but historically important in Colombia and the Ural Mountains.
