从金电解阳极泥中湿法回收金银试验研究

Recovery of Gold and Silver From Anode Mud by Wet Process

研究了用湿法处理电解金阳极泥,通过王水分金、水合肼还原金、水合肼还原银从金电解阳极泥中分离金和银。试验结果表明:银损失较低且纯度达99%;金纯度为99.8%,铸成阳极板后可满足金电解要求。该方法操作简单,金属回收率高,产品纯度高。

Recovery of gold and dilver grom electrolysis anode mud by wet process was researched .By aqua regia dissolving gold and hydrazine hydrate reducing gold ,hydrazine hydrate reducing silver ,gold and silver can be recovered effectively .The results show that silver loss rate is lower and purity reaches 99% ,gold purity is 99 .8% .The gold product can be cast anode for gold electrolysis .This method is simple and has higher metal recovery .
