Manganese makes up about one part in 1000 (0.1 ) of the Earth's crust, making it the 12th most abundant element. It most commonly occurs in silicates, oxides and carbonates. The oxides are the most abundant, and practically all of the metal is derived from them. The chief sources of manganese and its salts are the oxide.

Manganese Ore An Overview Sciencedirect Topics

Isobel Mc Dougall, in Handbook of Ferroalloys, 2013. 4.2.2 Sintering of Manganese Ore. The sintering process employed for manganese ore and the siliceous ores used to produce silicomanganese results in partial reduction of MnO 2, Mn 2 O 3, and Mn 3 O 4 in the ore to MnO by reaction with carbon in addition to agglomerating the fine ore and coke. New technology also utilizes addition of fluxes.
