ABSTRACT:
Manganese is recovered from its oxides by reacting a manganese oxide with fused calcium chloride or fused magnesium chloride to provide a liquid phase containing manganese chloride and fused chloride, and a solid phase containing reaction residue, the temperature of the reaction being above the melting point of the calcium or magnesium chloride but below the boiling point of manganese chloride in the reaction mixture. The liquid phase containing the manganese chloride is then subjected to electrolysis to deposit manganese metal upon the cathode and release elemental chlorine at the anode.
