Abstract
The electrorefining of crude lead was studied in a lead perchlorate-perchloric acid electrolyte. Curves of cathodic and anodic polarization of lead showed that with increasing in lead concentration the polarization of both electrodes decreased considerably. Even at high current density of 3A/d㎡ Ag, Cu, Bi and Sb were removed from lead as slime. In the presence of small amount of gelatine smooth and uniform thick cathode deposits were obtained. Current efficiency was 99.5∼99.9%.
