针对某含铜金矿石进行了氨氰法浸金及浸出贵液脱铜试验研究。其结果表明：在一定条件下，可获得较好的技术指标，浸渣金品位0．38 g／t，浸出贵液金、铜平均质量浓度分别为2．27 mg／L、61．94 mg／L，渣计金浸出率为89．44％；采用双氧水除铜，铜沉淀率为85．85％，氧化沉淀渣铜品位超过50％，可以铜精矿出售。
Gold extraction was studied from a gold ore with copper by ammonia cyanide leaching in the paper as well as copper removal from pregnant solutions .The leaching results showed that in certain conditions ,satisfactory tech-nical indexes could be obtained ,with leaching residues grade of 0.38 g/t,average mass concentration of gold and copper in leaching pregnant solutions respectively are 2.27 mg/L and 61.94 mg/L,gold leaching rate according to residues is 89.44 %.Hydrogen peroxide is used for copper removal ,gaining a copper precipitation rate of 85.85 %,and copper grade in the oxidation precipitation slags is over 50 %,making it possible to sell them as copper concentrates .
