摘要: 
A lead alloy anode for a cell for the electrowinning or electrolytic recovery of zinc consists of 0.05 to 0.25% by weight strontium and/or 0.05 to 0.1% by calcium in combination with 0.1 to 0.5 silver, balance lead. The cell is used in a method for the recovery of zinc at, for example, a current density of 160 to 630 amp/m2, a temperature of 30° to 46° C. and an electrolyte containing 40 to 70 g/l zinc and 165 to 220 g/l sulfuric acid.
