摘　　要：为确定搅拌工艺最佳的工艺参数组合,提供工艺设计参数,开展了某高含泥氧化矿浸出性能试验研究。通过搅拌浸出的条件试验,考察了温度、硫酸用量、液固比、磨矿细度等条件对铜浸出过程的影响规律,温度是影响浸出的关键因素,温度升高,铜浸出率明显提高。最佳的浸出工艺参数:温度为80℃、加酸量160 kg.t-1、液固比2∶1、磨矿细度74μm占65%,浸矿时间2 h,铜浸出率达到89.01%,耗酸187.91kg.t-1,浸出率与酸耗有较好的组合关系。In order to determine the optimal process parameters of agitation leaching and provide industrial process design parameters, experiments were carried out on leaching behaviors of copper oxide ore with high mud content. Experiments were carried out at different temperature, initial acid concentration, liquid-solid ratio and the grinding fineness. The results showed that the main factors affect the leaching efficiency was temperature. As the temperature increased, the copper leaching rate was significantly increased. Under the conditions at temperature of 80 ℃, the initial acid concentration of 160 g·L^-1 , leaching time of 2 h, liquid-solid ratio of 2：1 and grinding fineness of 74 μm 65%, the optimal copper leaching rate was 89.01%, and the acid consumption was 187.91 kg·t^-1.
