ABSTRACT:
Cermet material obtained from unused inert anodes, used inert anodes and cermet used in the production of inert anodes is beneficiated into a nonferrous metal concentrate composition from which metal values contained in the composition may be readily recovered by using a conventional smelting process. The invention also relates to the use of the composition in a smelting process for the recovery of metal values from the cermet composition of the invention.
