氯盐法从含硫铅渣中回收铅

Retrieve Lead from Bearing-Sulphur Lead Residue by Chloride Leaching

铅渣既是污染环境的有害物质，也是二次资源。本文采用ＮａＣｌ－ＦｅＣｌ３－ＣａＣｌ２酸性体系．对铅渣的浸出进行了研究，有效地解决了在大量元素硫存在下提取铅分离硫的问题。

Lead residue is pernicious pollutant it as also secondary resoLlre. Theleaching lead in NaCl-FeCl3-CaCl2 acidity system is studied in this paper. Theseperating lead problem from the residue containing a great quantify sulphur iseffectivelly solved as well.
