摘要
在含银废液中加入氯化钠生成氯化银沉淀，再将氯化银经湿法冶炼提纯制得高纯银。试验结果表明：银的直收率为９８．７８％，银粉纯度为９９．９９％。
By adding sodium chloride in silver bearing waste liquid to compound silver chloride,then smelting the silver chloride in wet process and purifying it,the silver with high purity are developed.The result of experiment shows that the direct recovery of silver reaches 98.78%,its purity comes to 99.9%.This paper gives an introduction in detail.
