A method of recovering metal from a process material comprising metal and a component that is more volatile than the metal, the method comprising transporting the process material to a retort provided in a furnace, wherein the retort is under vacuum and from the process material. Operated at a temperature sufficient to cause sublimation of the components of the product, thereby producing a refined metal, depositing the sublimated component on a cold surface, removing the refined metal from the retort, and depositing Removing the component from the cold surface.
