摘　　要：采用搪瓷釜、回转窑、真空蒸馏炉等设备处理铅精矿在熔炼、制酸过程中产生的电雾酸泥,综合回收电雾酸泥中的金、银、硒等元素,最大程度实现资源的回收利用。生产实践证明,采用本工艺能够有效回收电雾酸泥中的硒元素,并将金、银富集在焙砂中返回配料系统回收,提高金、银直收率,实现硒元素的综合回收。Sulfuric acid mud from lead sulfide concentrates smelting was treated by enamel kettle,rotary kiln,and vacuum distillation furnace to comprehensively recover gold,silver and selenium.The plant practice proves that this new process can recycle selenium effectively.Gold and silver is enriched in calcining and recovered by returning to batching system.
