Ferroalloys Processing Equipment. Isobel Mc Dougall, in Handbook of Ferroalloys, 2013. 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.

It is commonly obtained through manganese ore in the form of manganese oxide (also known as pyrolusite), or through iron ores. Manganese production is thus often subsumed under iron mining. Besides their ores being regularly obtained from the same mines, manganese and iron are further linked due to their complementarity in steel production.
