Manganese Metal Company begins commissioning South Africa’s first battery-grade manganese sulphate plant

Manganese Metal Company (MMC) has commenced commissioning South Africa’s first high purity manganese sulphate monohydrate (HPMSM) facility at its Mbombela refinery in Mpumalanga. This is a significant step for the country which has long been the world's largest supplier of manganese ore. MMC has operated in Mbombela since 1974 as the world's largest non-Chinese producer of selenium-free electrolytic manganese metal (EMM). It sources ore from the Kalahari Manganese Field in the Northern Cape. The company has added HPMSM production through a brownfield expansion to its existing refinery. MMC is wholly-owned by South African companies.
