Purification of copper by electrolysis

Apr 19, 2021

The invention discloses a purification process of copper electrolysis waste liquid, wherein the copper electrolysis waste liquid is introduced into a winning cell to dissolve out black copper. The purification process is characterized in that the copper iron concentration of post-electrodeposition liquid flowing out of the winning cell is 0.1-5 g/l
