摘　　要：针对湿法炼锌熔铸时产生的高氯锌浮渣不能直接回用到生产系统的问题,通过试验,提出部分锌浮渣代替锌粉中和置换沉铟,剩余锌浮渣直接浸出,沉铟后液及浸出液混合后再用脱氯剂脱氯,硫酸锌溶液直接进入湿法炼锌系统回用,以此达到经济利用锌浮渣的目的。In view of the problem that the high chloride zinc dross produced during the melting and casting in zinc hydrometallurgy can not be directly reused in the production system,through the test,it is put forward,that partial zinc dross instead of zinc powder neutralizes and displaces indium,remaining zinc dross is leached directly,the solution after indium deposition and the leaching solution is mixed and then dechlorinated with dechlorination agent,and the solution of zinc sulfate is directly pack to the zinc hydrometallurgy system for reuse,so as to achieve the purpose of economic utilization of zinc dross.
