Manganese became the metal that allowed humankind to move into the modern steel age. It is added into steel for its deoxidizing and desulfurizing properties. Every tonne of raw steel produced today contains between 4 kg and 7 kg of manganese metal, a relatively small amount, but it accounts for almost 90% of all manganese ore mined.
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.
