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 ...

An active natural manganese dioxide mineral for use in dry battery cells is produced from a natural manganese dioxide ore by reacting the ore or a preconcentrate thereof with a solution of an acid. The acid reacts with the carbonates, such as calcium carbonate, to produce water-soluble salts which are then washed away. The resultant mineral can have an MnO 2 content of 80% by weight or more.
