摘要
研究了一种环保型的边角料银的回收工艺。采用本工艺回收银石墨边角料中的银,银的回收率达99.6%以上,回收银的质量符合GB/T 4135-2002(IC_Ag99.99)标准。
A environment-protective type methods of silver recovery was studied in this paper. The result shows that the recovery percentage of silver is up to 99.6 % by adopting this methods to extrusion silver graphite scraps, and the silver quality accords with IC-Ag99.99 standard.
