摘　　要：试验采用C410树脂,对氯化浸金稀溶液进行预分离富集,研究了在静、动态条件下C410树脂对金和银的吸附、解吸性能、饱和吸附容量及杂质的干扰等。在试验最佳条件下,对某矿样氯化浸出液,金、银的吸附率分别达99.89%、86.5%,解吸率分别达99.32%、99.72%;解吸液经化学沉淀、溶金银、还原,获得的金、银的纯度达99.995和99.993%。C410 resin is used to pre-separate and enrich chloride gold leaching dilute solution in experiments. The adsorption and desorption performance of C410 resin to gold and silver, saturated adsorption capacity and impurity disturbance are investigated in still and dynamic conditions. In the optimal conditions, the adsorption rate of gold and silver is respectively 99.89 % and 86.5 %, and the desorption rate of gold and silver is respectively 99.32 % and 99.72 % for a certain chloride leaching solution. After chemical deposition, metal dissolution and reduction, the purity of gold and silver is respectively 99. 995 % and 99. 993 %.
