摘要
采用过硫酸盐脱铜工艺处理高铜载金炭,可选择性地脱除载金炭中的铜,铜脱除率达89%,金损失率很低;脱铜溶液循环后采用萃取—电积工艺回收铜。该工艺流程短,药剂用量少,处理时间短,环境友好,铜脱除率高,成本低,具有较好的应用前景。
The decoppering from high copper activated carbon carrying gold by a persulfate solution were described. By this method, removal rate of copper in gold-bearing carbon can reach 90% while gold loss rate is very low. Recovery of copper from copper solution by solvent extraction process. This process has the advantages of short process, low regent dosage, short treatment time, high environmental friendliness, low cost, and so on. It has good application prospect.
