The surface of the electrowon copper is uneven with grooves along its edges

2021-03-08View Original

Thread Content

After the electrode copper is deposited, the upper edge is not smooth enough, appearing like gullies formed by erosion. Currently, a copper sulfate solution with 33 g/L of copper and an acidity level of 190 g/L is used; electrolysis is carried out in electrolytic cells using stainless steel cathode plates as the cathodes and lead anode plates as the anodes. The distance between the electrodes is 100 mm, and the current density is 140 A/m2
