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.
Claims11
A smelter feedstock composition from which metal values are recoverable in a smelter, said composition consisting essentially of comminuted cermet which has been isolated from inert used anode, inert unused anode, inert anode manufacturing residue, or combinations thereof;
- which further comprises a fluxing additive which facilitates smelting of said composition in a smelter;
- and wherein said composition has been roasted under oxidizing conditions to oxidize a portion of said composition.
A smelter feedstock composition from which metal values are recoverable in a smelter, said composition consisting essentially of comminuted cermet and further comprises an ore concentrate.
