摘　　要：本文根据生产实践,以分析系统含锰变化时锌湿法生产情况为出发点,指出高锰时短期应采取降低酸锌比同时配合减少锰粉加入量的技术措施,长远应考虑如何解决老电解锌厂系统内累积杂质有效开路的问题,并结合锌浸出渣二次洗涤前后杂质变化,总结系统锰的平衡。Based on the production practice of zinc hydrometallurgy production , Through analyzing the change of manga-nese-bearing zinc hydrometallurgy process , it is pointed out in the high manganese condition that short-term measures should be taken to reduce acid zinc ratio with the reduction of manganese powder at the same time , and in the long run measures should be taken to solve the problem of effective open circuit for accumulated impurities from old electrolytic zinc plant system .Combined with change in the impurities in zinc leaching residues during the second washing , the balance of manganese in system was summarized .
