Abstract

1483126 Electrolysis of cyanide wastes and cell therefor ELECTRICITY COUNCIL 2 April 1976 [3 Jan 1975] 267/75 Addition to 1423369 Heading C7B Dilute metal cyanide solutions e.g. electroplating rinse, are electrolyzed in a cell containing a bed of non-conducting particles fluidized by upward passage of the solution, the bed being in contact with an anode and cathode both having apertures or surface irregularities and having a relative effective cathode: anode area of 1À3 to 2:1. Metal, e.g. Cu, Zn, Ag is cathodically recovered, while cyanide is anodically oxidized. Electrodes of Pt or PbO 2 on Ti, or of graphite are useful; the cathode may be Cu. Mesh, perforated or rod-like electrodes are useful, with holes large enough to pass the particles which may be of sand, glass or plastics. A porous cell base-plate may admit electrolyte which is recirculated via a rinse tank for articles from an electro-plating operation.
