Sustainable Mining and Metallurgy

This paper elaborates on the process control of large-plate lead electrolysis, including impurity control in the early stage of large anode plate preparation, quality requirements for starter sheet preparation process, loading large plates into the cell and the electrolyte, control over the circulation speed and temperature of electrolyte, and purification of anode slime washing water. This process control can reduce the impact of impurities, improve the quality and quantity of precipitated lead, lower DC power consumption and thus achieve energy conservation and consumption reduction.
