Metallurgical anthracite
Petmin’s metallurgical anthracite competes with bituminous coals, chars and cokes as a carbon feedstock in the metallurgical industry.
Anthracite is exported via Richards Bay to iron ore pelletising and sintering markets, with the balance of production sold to the South African ferro-alloy industry.
Future potential markets include the ferromanganese industry and titanium smelters. By calcining the Somkhele anthracite, there is potential to upgrade its quality by increasing carbon and reducing volatiles, which will help to penetrate niche metallurgical markets.
Energy coal
Petmin’s low volatile, high-ash energy coal is exported to markets around the world and primarily used in the cement and low-volatile power station markets.
