摘　　要：对铜渣氧压酸浸法制备硫酸铜工艺进行了研究。结果表明,采用氧气或富氧空气加压浸出铜渣,在压力0.2MPa、温度80℃、初始硫酸浓度10%的条件下浸出2h时,铜浸出率达到92%以上。浸出液不经蒸发浓缩,可以直接冷却结晶生产结晶硫酸铜,过程能耗低,无废水产生。The preparation of copper sulfate from copper slag with oxygen pressure acid leaching process was studied. The results show that the leaching rate of copper is above 92% under the conditions including pressure of 0. 2 MPa, temperature of 80℃, initial sulfuric acid concentration of 10% and leaching time of 2 h. The crystallized copper sulfate can be produced from lixivium by direct cooling and crystallization process without evaporation and concentration. This process has the advantages of low energy consumption and no production of waste water.
