中文摘要: 通过单因素试验考察了鼓气速度、硫酸浓度、浸出温度、液固比、浸出时间对黑铜渣中铜、砷浸出率的影响。结果表明,在鼓气速度0.8 m3/h、硫酸浓度1.5 mol/L、浸出温度80 ℃、L/S=6、浸出时间3 h的优化条件下,铜、砷浸出率分别达到94.4%、92.1%。
Abstract:The effects of bubbling speed, concentration of sulfuric acid, temperature, L/S, and leaching time on leaching rates of copper and arsenic from black copper slag were investigated by single factor experiment. The results show that leaching rate of copper and arsenic is 94.4% and 92.1% respectively under the optimum conditions including bubbling speed of 0.8 m3/h, concentration of sulfuric acid of 1.5 mol/L, leaching temperature of 80 ℃, L/S=6, and leaching time of 3 h.
