研究从含铜废渣、废液中提取硫酸铜的方法,以减少污染、回收资源.利用含铜废渣、废液生产海绵铜,再通过置换、氧化、酸化、结晶以及重结晶等步骤制备五水硫酸铜晶体.通过上述方法由含铜废渣、废液制备出硫酸铜晶体.该方法所用设备简单,操作简便,铜的回收率高,硫酸铜产品质量达到化学纯(CP)等级.%In order to reduce pollution and recycle the resources,a method of extracting copper sulfate from waste residue and waste liquor containing copper was explored. Spongy copper was produced from waste residue and waste liquor containing copper,and then copper sulphate pentahydrate crystal was produced after the steps of displacing, oxidizing,acidifying, crystallizing, and recrystallizing. Copper sulfate crystal was produced by the above-mentioned method. This method had advantages, such as simple equipment, easy operation, and high recovery rate of copper. Product quality of copper sulfate is up to chemical reagents grade.
