Abstract
A method for recovering manganese metal from ferromanganese is disclosed which comprises: PA1 A. contacting ferromanganese and an iron chloride selected from the group consisting of ferrous chloride and ferric chloride in a molten bath of a metal chloride wherein the metal has a greater chemical affinity for chlorine than iron, to provide a liquid phase containing manganese chloride and a solid phase containing iron precipitate; PA1 B. separating the manganese chloride liquid phase from the iron precipitate solid phase; PA1 C. electrolyzing the manganese chloride liquid phase to provide manganese metal.
