All about our manganese ore | Eramet

Manganese fines. With their high manganese content, our fines have been developed for the production of silicomanganese (SiMn). This ore is used to improve process performance (less waste, reduced energy consumption), particularly in the production of agglomerates. Its low iron content makes it highly complementary to iron rich ores.

Manganese - USGS

2021-2-4 · Manganese ore containing 20% or more manganese has not been produced domestically since 1970. Manganese ore was consumed mainly by six firms with plants principally in the East and Midwest. Most ore consumption was related to steel production, either directly in pig iron manufacture or indirectly through upgrading the ore to ferroalloys.
