湿法处理铜阳极泥工艺研究(Ⅱ)——金的选择性浸出

Study on Hydrometallurgical Process for Copper Anode Mud. ——Selective Leaching of Au

对脱除了铜、硒、碲的铜阳极泥进行了金的浸出研究。结果表明 ,用 Na Cl O3 作浸出剂 ,银很少被浸出 ,而金的浸出率达到 99.2 2 % ,直收率达 98.4 % ,总回收率为 99.2 % ,金、银分离比较彻底。

Selective leaching of Au from copper anode mud from which Cu,Se,Te had been removed by hydrometallurgical process is investigated.The results show that leaching rate of gold is 99.22%,direct recovery rate and total recovery rate are 98.4% and 99.2%,respectively.Silver is not leached.
