我厂锌冶炼车间产出的铸型渣含锌在60%以上,含氯1%左右,由于渣含氯较高,将此种铸型渣返回湿法炼锌系统进行回收,在我厂具体条件下是不适宜的。为了回收渣中的有价金属,消除环境污染和扭亏增盈,我们采用生产氯化锌的工艺回收铸型渣中的锌,取得了良好效果,铸型渣中锌的回 I plant zinc smelting plant output of the casting slag containing zinc in more than 60%, 1% chlorine content, due to the higher chlorine residue, the casting slag back to wet zinc recovery system, in our plant specific Conditions are not suitable. In order to reclaim the valuable metal in the slag and eliminate the environmental pollution and increase the profit by turning losses into profits, we adopted the process of zinc chloride production to recover the zinc in the foundry slag and achieved good results. The zinc back in the mold slag
