Abstract
A process is provided to produce pure elemental metal; such as manganese, by reacting a halide of the elemental metal with aluminum. The halide of the elemental metal is present as a molten pool wherein the temperature at the bottom of the pool is sufficient to maintain the elemental metal molten and the temperature at the top of the pool is below the boiling point of the metal halide in the pool. Aluminum halide is removed as a vapor overhead and a layer of molten metal collects at the bottom of the pool of molten halide.
