Effect of cooling ways on properties of Al/Pb-0.2%Ag rolled alloy for zinc electrowinning

Influence of F-Doped β-PbO2Conductive Ceramic Layer on the Anodic Behavior of 3D Al/Sn Rod Pb−0.75%Ag for Zinc Electrowinning

“…Al-substrate Pb-alloy anodes have demonstrated good prospects for use in the electrolyte industry. [12][13][14] However, the deposition of continuous Pb alloy coatings on Al substrates from aqueous solutions is difficult due to the facile formation of a dense insulating oxide layer on the Al surface. Furthermore, the process is long and complex, and controlling the quality of the Al/Pb-Ag composites using this method is difficult.…”

A novel CF/Ti/β-PbO2 composite anode for zinc electrowinning: preparation, electrochemical properties and application

“…The anode life test was carried out in a simulated zinc electrolyte, the CF/Ti/b-PbO 2 composite anode (10 mm × 10 mm) was employed as the anode, the aluminum sheet (30 mm × 30 mm) was employed as the cathode, the current density was 20 000 A m −2 , the temperature was 35 °C, and the data were recorded every 30 s. The criterion for judging the failure of the anode was the shedding of the effective layer or the sudden change of the cell voltage. 26…”

Electrochemical behavior of zinc anode in acidic zinc electrolyte -influence of lead as an impurity in zinc anodic dissolution

“…This metal is produced from its ores of sulfide, oxide and siliceous types via pyro-electrometallurgical route. 85-90% of the world's zinc are produced by hydro-electrometallurgical routes [2][3][4] and from zinc sulphate electrolyte refining [5,6]. Zn obtained by this route still contains a quantity of impurity of about 1% of lead.…”
