摘　　要：对云南某低品位氧化铜矿石进行了硫酸浸出试验研究,对影响铜浸出的各因素进行了考察。试验结果表明,在常温、液固体积质量比4∶1、硫酸质量浓度30 g/L、搅拌50 min、活化剂添加量5 g/L条件下,铜浸出率可达65%。The tests on leaching of a low grade oxidized copper ore in Yunnan using sulfuric acid have been made. Influence factors on leaching of copper were examined. The experimental results showed that copper leaching of 65% can be obtained under the conditions of room temperature,V（liquid） ： re（solid）of 4 L/kg,sulfuric acid concentration of 30 g/L, leaching time of 50 min, activating agent concentration of 5 g/L.
