A process for beneficiation of low-grade manganese ore

2/1/2021· In order to economically and effectively utilize low-grade manganese ores from Indonesia, a process of producing a high-grade manganese concentrate (Mn >49 wt%) and calcium sulfate whisker is proposed in this paper. Low grade manganese ore is beneficiated with hydrochloric acid as the leaching agent to obtain a manganese concentrate.

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.
