摘要
分析了锌电积过程槽电压、直流电耗高的原因,采取增大导电棒外部循环水量、降低溶液镁离子含量、控制电解槽液位及优化槽面管理等措施,锌电积系统直流电耗从3119 kWh/t·Zn稳定降至3050 kWh/t·Zn以下,取得了较好的效果。
It is analyzed the causes of high cell voltage and high DC power consumption in zinc electrowinning process,the following measures were adopted,the circulating water volume outside the conductive rod was increased,magnesium ion content in solution was decreased,cell face management was optimized and so on,then the DC power consumption of zinc electrowinning system was stably decreased from 3119 kWh/t·Zn to 3050 kWh/t·Zn,the effect is good.
