Abstract
1412836 Anodes for electrowinning IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 22 April 1974 [17 April 1973] 18454/73 Heading C7B [Also in Division B3] A method of making a composite structure comprised of a precious metal bonded to a substrate of a film-forming metal includes assembling a sheet of precious metal foil 3 between a substrate 1 of a film-forming metal having a high electrical conductivity metal core 2 e.g. of copper or aluminium, and a protection and lubrication material 4, and rolling the assembly to elongate the components and metallurgically band them together. The precious metal is selected from the group platinum, iridium, rhodium, palladium, cerium, ruthenium, gold and alloys of two or more of these. The film-forming metal is selected from the group titanium, tantalum, niobrium, zirconium or an alloy of one or more of these metals having comparable anodic properties to the pure metal. The substrate comprises a titanium block drilled to receive cleaned copper cores 2, the block being pickled prior to receiving the cores. Platinum foil 3 is placed on the block and the block and foil are placed in a copper chest, which comprises the protection and lubrication material. A cleaned lid 5 is electron beam welded to the chest. The assembly is hot rolled to bond the foil, block and rods together and the copper chest is pickled off. Alternatively the composite structure is made by placing niobium sheets (8), (9), Fig. 2 (not shown), on either side of a copper core (7). Ruthenium foil, (10), (11) is placed on the sheets (8), (9) and a pair of dished copper plates (12), (13) are placed on the ruthenium layer and crimped together at their edges (14). The surfaces of the components are cleaned before assembly. The assembly is hot rolled to produce a copper core niobium block faced with platinum after the plates (12), (13) have been pickled off. The protective material prevents the precious metal being picked-up during rolling and is readily lubricated. The composite structure may be used as an anode in the electrowinning of copper in which case the outer copper sheets can be left in position as they will be removed electrolytically during initial operation of the electrowinning cell.
