Manganese Ore - an overview ScienceDirect Topics
Manganese ores will always contain some iron oxides. Reduction of the iron oxides in the ore is probably almost complete when the temperature reaches 1200°C. The product will be a carbon-saturated iron alloy with an increasing content of manganese at increasing reductions in temperature.
