Abstract
A method for producing a metal by reduction of a metal halide characterized by the steps of feeding into a plasma such as the arc heated stream of an arc heater, a quantity of a reducing metal such as an alkali or alkaline earth metal, feeding into the plasma a quantity of a metal halide, maintaining the temperature of the reaction chamber wall higher than the vapor point of the alkali metal chloride formed or alkaline earth metal chloride formed but lower than the melting point of the elemental metal, co-products formed being an elemental metal and a gaseous salt, projecting the co-products into the reaction chamber to cause the metal to deposit on the interior wall of the collection chamber, removing the gaseous salt, heating the metal deposited on the interior of the reaction chamber with the arc heated stream thereby causing the elemental metal to fall gravitationally or be blown into an associated receptacle in the form of solidified globules and/or crystals and/or granules and/or large diameter powders.
