摘要
采用洗氯—硫酸熟化水浸—置换铜—中和除铁镁—浓缩结晶硫酸锌工艺从冶炼厂锌烟尘回收有价金属锌、铜,全流程锌、铜的回收率分别达97.1%、96.8%。
An acid wash - leaching with sulfuric acid curing-cementation of copper by iron- impurities removing - crystallization of zinc sulfate process was used to recover the valuable metal zinc and copper from the zinc dust of smelter. Recovery yields of zinc and copper by this process were 97.1% and 96.8% , respectively.
