Ferro Manganese is a ferro alloy with high content of manganese is made by heating a mixture of the oxides MnO2 and Fe2O3 with carbon usually as coal and coke in either a blast furnace or an electric arc furnacetype system called a submerged arc furnace. The oxides undergo thermal reduction in the furnaces producing the ferro manganese.
