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

Manganese USGS

The black manganese layer is about 45 meters thick and consists of a 20-meter-thick ore bed and two lower grade subeconomic beds. The slightly folded layering is shown by the shapes of the various mine . benches. Lighter material in the background is waste that must be stripped to expose the ore bed; this waste material is used as backfill in
