ABSTRACT:
A process for reducing a metal from a metal halide characterized by the steps of feeding into the arc heated stream of an arc heater a quantity of a reactant metal such as an alkali or alkaline-earth metal, feeding into the arc stream a quantity of a metal halide, which metal has a melting point higher than the boiling point of the co-product salt formed by reduction of the metal, the co-products being a liquid elemental metal and a gaseous salt, projecting the co-products into a reaction chamber tangentially to cause the liquid metal to separate centrifugally from the lighter, gaseous salt, and depositing the liquid metal in an associated receptacle.
