摘　　要：研究了采用加压酸浸法从吹炼转炉渣中浸出铜,考察了硫酸浓度、浸出温度、浸出时间对铜浸出率的影响。试验结果表明:吹炼转炉渣细磨后,在硫酸初始质量浓度150g/L、浸出温度70℃、浸出时间4~5h条件下,铜浸出率达97%以上,渣中铜质量分数小于3%,浸出效果较好。Leaching of copper from the converter slag using sulfuric acid by pressure was studied. The influences of sulfuric acid concentration, leaching temperature and leaching time on leaching rate of copper were examined. The results show that leaching rate of copper is above 97%, copper in leaching residue is less than 3% under the optimum leaching conditions of leaching temperature of 70 ℃, sulfuric acid concentration of 150 g/L and leaching time of 4-5 hours.
