Abstract
811,442. Electrolytic recovery of non-ferrous alloy coatings. CLEVITE CORPORATION. Aug. 3, 1955 [Nov. 22, 1954], No. 22284/55. Class 41. A non-ferrous lead-containing copper base alloy coating is separated from a ferrous body by anodic dissolution in a strongly alkaline aqueous electrolyte containing an alkali metal cyanide and from 5 to 20 g./l. tartrate radical with an anode-electrolyte potential of not more than 0.8 volt, the alloy being cathodically deposited. The alloys may contain 1 to 40 per cent lead and as little as 55 per cent copper, while other non-ferrous metals such as tin and zinc may be present. Preferably the electrolyte contains the metal ions in the same proportion as in the alloy coating. The cathode may be of steel or copper and the scrap to be treated is contained in steel baskets which are moved to tumble the contents and assist in anodic dissolution of the alloy coating, the electrolyte being circulated by a pump through an external filter. To obtain the alloy in powder form, the bath is gently agitated by movement of the cathode so that a cathode current density of 30 to 80 or even up to 100 amps./sq. ft. may be used, the spongy deposit being readily scraped off the cathode and crushed. In the absence of agitation and with a cathode current density of up to 20 amps./sq. ft. an adherent cathode deposit is obtained.
