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 ...
