【Abstract】 Copper sulfate can be obtained from waste electrolyte by chemical deposition. In the course of experiments, the best range of pH in eliminating impurity elements ’ process is 3.0-3.5. In the depositing of copper process,it is 5. 5-6. 0. The percentage recovery of copper process is 5. 5-6. 0. The percentage recovery of copper is 96. 0%. This method is simple and the investment is less, so the process has a broad prospect of application in the industrial production and environmental protection.更多还原
