ferruginous manganese ore beneficiation processes

Carbothermic Reduction of Ferruginous Manganese Ore for

especially in ferruginous manganese ore treatment. Another approach, reduction-magnetic separation, is also developed for iron and manganese beneficiation from ferruginous manganese ore [6,15–21]. In this process, iron minerals are transformed to ferromagnetic substance (Fe3O4 or Fe) for magnetic separation purposes.
