摘要
采用树脂吸附法,利用QPTU树脂,控制温度30~40℃,回收沉金后液中的Au、Pt、Pd贵金属,可以控制尾液含金、铂、钯在0. 2 mg/L以下。结果显示,该树脂对沉金后液中的Au、Pt、Pd都有很好的吸附效果;在此运行温度条件下并没有发生降解;该树脂的吸附突破顺序依次是Pt、Pd和Au。
Precious metals such as gold,platinum and palladium were recycled from gold-precipitated liquid by resin adsorption,using the QPTU resin,controlling the temperature of 30 ~ 40 ℃. This method can control the concentration of gold,platinum and palladium in the tailings below 0. 2 mg/L. The results showed that the resin had a good adsorption effect on Au,Pt and Pd in the gold-precipitated liquid. No degradation occurred at this operating temperature. The adsorption breakthrough order of the resin was Pt,Pd and Au.
