The smelter, established in 1913, is part of the leading industrial environment at Herøya, one of Norway’s largest industrial areas. This location provides opportunities to further develop our processes, including resource utilization and circular economy.
The plant is the most flexible in terms of product qualities of all of Eramet’s manganese alloys smelters.
- Two furnaces
- Ferromanganese refining plant (Manganese Oxygen Refining – MOR)
- Ferromanganese: HC FeMn, MC FeMn 1,0-1,5%, LC FeMn 0.5%*
- Silicomanganese: SiMn Standard
- By-products for external sale: MOR dust, Silica Green Stone (SiGS), energy-rich oven gas. In addition, large quantities of by-products are circulated internally.
