1-1-2012 · 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 ...

Manganese processing | Britannica
20-7-2020 · Manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such
Production of manganese (II) sulphate from …
A new method is described for the production of manganous sulphate from low‐grade manganese ores. The ore is first treated with a calculated amount of concentrated sulphuric acid at 200–220° to form manganic and ferric sulphates, and then heated at 500–640° for 90 min.
