ABSTRACT:
A method and apparatus for the concentration and recovery of platinum family metals from ceramic materials is disclosed, wherein the metal desired is first transported from the ceramic material through the utilization of a temperature gradient in a specially adapted furnace utilizing the volatile characteristics of the oxide of the metal desired. The volatile oxide is deposited upon a nucleation surface where it is reduced by means of hydrogen as the furnace cools to recover the metal.
