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
Claims12
A smelter feedstock composition from which metal values are recoverable in a smelter, said composition consisting essentially of comminuted cermet and a fluxing additive to facilitate smelting of said feedstock composition in a smelter wherein said cermet is isolated from inert used anode, inert unused anode, inert anode manufacturing residue or combinations thereof;
- and said smelter composition has been agglomerated or pelletized whereby said composition is in the form of granules or pellets.
A method for recovering metal values from smelter feedstock which comprises smelting said feedstock in a smelter which produces a first component containing said metal and a second component which is slag;
- and recovering said metal values from said first component;
- wherein said smelter feedstock composition consists essentially of comminuted cermet and a fluxing additive to facilitate smelting of said feedstock composition in a smelter;
- wherein said cermet is isolated from inert used anode, inert unused anode, inert anode manufacturing residue or combinations thereof;
- and said smelter composition has been agglomerated or pelletized whereby said composition is in the form of granules or pellets.
A method for treating inert anodes which comprises isolating cermet from said anodes;
- comminuting said isolated cermet to produce comminuted cermet;
- optionally using some or all of said comminuted cermet as a component in the manufacturing of inert anodes which contain cermet as a component thereof;
- and using all or a portion of said comminuted cermet as smelter feedstock in a smelting procedure to thereby recover metal values from said cermet;
- wherein said smelter feedstock further comprises ore concentrate.
