Mineral Commodity Report 7 - Manganese
manganese oxide ore is reduced to manganese ferroalloys in an electric arc furnace with aluminium and silicon. Blast furnace-type operations are still used in some countries to make high-carbon ferro-manganese. Higher grades of manganese, including manganese metal, are commonly produced by the electrolysis of sulphate solutions of manganese.
