| Abstract: | The recovery process of copper and nickel in waste electrolyte has been developed by using ion exchange membrane electrolysis, a plenty of good quality sheet copper, sponge copper and black copper can be reclaimed and attached on the cathode, 23-27g/L density H2SO4 solution can be reclaimed and reserved in the anode chamber. When using diffusible analysis method, pure diluted H2SO4 solution and nickel sulfate can be separated from the residual electrolyte. This paper also discussed the most optimized electrolyzing process parameter and acid separating modulus. |
