内容記述 | Corrosion of lead anodes containing 1% silver in the electrowinning of zinc was investigated by using solutions with and without manganese in amount up to 0.05 to 8g per liter at various temperatures and current densities. The effect of manganese on the corrosion of lead anode was estimated by comparing both results from electrolysis. Manganese dioxide even in vary small amount acts favorably to prevent corrosion of the lead anode by depositing itself on it which results in decreasing lead in the anode slime. However, a higher concentration of manganese does not show corresponding improvement in its concentration. On the contrary, the standard deviation of measurements of lead in the deposited zinc of the anode slime increases with increase in manganese and the protective effect of manganese film suffers more intensively from the electrolysis conditions. Thus, the electrolyte solution containing manganese in relatively low concentration is preferable with respect to stabilities of the oxide film and the anode potential. The effect of manganese mentioned above, however, is not always the same in the anodes tested. Peculiarity of the respective anode influences its corrosion rate so strongly that the protective effect of manganese hides itself in the specific corrosion rate of the anode to be tested. Therefore, there results a case in which it seems as if manganese had reverse effect on the anodic corrosion. | |||||
