| Abstract: |
| In order to reduce the phenomenon of cathode nodules in the electrolytic process of high current density copper, reduce the residual rate and improve the current efficiency. Based on multiple physical field coupling theory and orthogonal experiment method, the influences of inlet tube radius, anode bottom fillet radius and electrode spacing on electrolytic refining of copper were studied. Single factor analysis shows that the current efficiency and copper deposition uniformity increase first and then decrease with the increase of inlet pipe radius or anode fillet radius. With the increase of electrode spacing, the current efficiency decreases and the thickness of copper deposition becomes uniform. The structure parameters of the electrolytic cell with excellent copper electrolytic refining effect were analyzed by orthogonal experiment as follows: inlet tube radius 3.5mm, anode bottom fillet 4 mm, pole spacing 110 mm. This paper provides theoretical guidance for improving the production efficiency of electrolytic cell. |
