Abstract:In this article, the reason for the formation of the high bismuth electrolysis system is briefly described, and the influence of bismuth impurity on the quality of electrolytic copper during the copper electrolysis process is introduced. The Bi content of the anode plate is tracked, the electrolysis process parameter control is stabilized, the self-purification ability of the electrolysis system is improved,and the electrolysis liquid filtration is strengthened, liquid purification capacity is improved, the measures for electrolysis production organization are strengthened during overhaul, the stable control of the high bismuth electrolysis system is realized.
