Abstract

1434334 Electrowinning metals ELECTRONOR CORP 29 Jan 1974 [29 Jan 1973] 04165/74 Heading C7B In a process and cell for metal electrowinning, the active anode area is 1À5-20 times less than the active cathode area, whereby the anode/cathode current density ratio is 1À5-20:1. The anode may comprise a series of parallel coplanar rods 34 arranged parallel to and spaced 20-150 mm from a steel sheet cathode. The rod axial spacing may be 10-100 mm, with closer spacing at the ends, and the rod diameter may be 2-16 mm. The rods which may taper at their ends may be round, square or rectangular in section, or may be replaced by strips or mesh. Alternative configurations are given Figs. 3-5, (not shown). The rods may be of a valve metal e.g. Ti, optionally on a Cu core, and have an electrocatalytic conductive coating of one or more oxides, nitrides, carbides or sulphides of Au, Pt, Ag, Pd, Ir, Ru, Os, Rh, Fe, Ni or Cr with or without one or more oxides of a valve metal (e.g. TiO 2 , Ta 2 O 5 ), Fe, Ni, Sn, Al, Co or Cr. A cell with an e.g. asbestos diaphragm may be used. Current density ranges specified are 1000-2000 A/m<SP>2</SP> anodic for a cathode c.d. of 300 A/m<SP>2</SP>. Metals electro-deposited are Cu, Zn, Co (from acid sulphate baths) or Ni (from an acid sulphate or H 3 BO 3 buffered chloride bath).
