Zusammenfassung:A process for recovering a metal in the form of a metal halide from a metal-containing source is described, the process comprising the steps of: -(i) forming a solid metal halide containing product by contacting the metal-containing source with a gaseous halide in an oxidising environment and at a temperature below the vaporisation temperature of the metal halide of interest; (ii) heating the metal halide containing product formed in step (i) to a temperature at or above the vaporisation temperature of the metal halide to form a gaseous metal halide containing product; and (iii) condensing the gaseous metal halide containing product of step (ii) to recover the metal halide of interest.
