摘　　要：研究了采用空气氧化—酸浸法从铜阳极泥中湿法预脱铜,考察了温度、反应时间、液固体积质量比、硫酸质量浓度及空气通入速率对铜浸出率的影响,确定了脱铜最优工艺条件。结果表明:在温度80℃、反应时间3 h、液固体积质量比10/1、硫酸质量浓度150 g/L、空气通入速率0.2 L/min、搅拌速度300 r/min条件下,铜脱除率达70%,此方法经济环保,可用于从铜阳极泥中脱除金属铜。Removal of copper from anode slime by air oxidation—acid leaching method was studied.The effects of temperature,reaction time,liquid volume/solid mass,sulfuric acid mass concentration and air inflow rate on leaching of copper were examined,and the optimal process conditions for removal of copper were determined.The results show that the copper removal rate can reach 70% under the conditions of temperature of 80℃,reaction time of 3 h,liquid volume/solid mass of 10/1,sulfuric acid mass concentration of 150 g/L,air inflow rate of 0.2 L/min and stirring speed of 300 r/min.The process is economical and environmentally friendly,and can be used to remove copper from anode slime.
