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.

Abstract. To support a risk assessment of manganese exposure in two communities living within a manganese mining district a cross-sectional study was performed on a sample of the adult population of long-term residents. One community was exposed to a point source from an ore primary refining plant. Manganese is an essential mineral for human life.
Dec 31, 2019 In 2019, Australias manganese ore production totalled approximately 7.5 Mt (Table 2 Table 3). The total tonnage of manganese ore mined is approximately twice the tonnage produced because of yields of around 50% after beneficiation. Export data for Australias manganese products, including manganese ore, were not available.
