| 摘 要： | 对采用硝酸氧化工艺预处理东北寨难浸金精矿进行了试验研究.试验结果表明:金精矿经硝酸氧化浸出后,精矿中的S、As、Fe以及其它有色金属元素进入浸出液,通过加入石灰沉淀被有效除去;氧化浸出渣中金经氰化浸出,金的浸出率可达到95.56%.

| Abstract: | An experimental research on nitric acid oxidation pretreatment of refractory gold concentrate was carried out in Dongbeizhai gold mine. It is revealed that after nitric acid oxidation pretreatment, S, As, Fe and other non ferrous metal is extracted into the lixivium, and can be precipitated with lime. The gold recovery rate of the oxidized residue can reach 95.56%. |
