Effect of Jet Flow between Electrodes on the Cathode Quality in Copper Electrorefining with High Current Density
Abstract
:1. Introduction
2. Experimental Details
3. Results and Discussion
4. Conclusions
- In the conventional bottom-inlet/top-outlet mode, an increase in electrolyte circulation rate has a limited effect on the decrease of the surface roughness of cathode copper.
- When a jet flow is introduced between the cathode and the anode, the electrolyte circulation rate has a large influence on the surface roughness of cathode copper, and the two are negatively related. When the circulation rate is small, the surface roughness of cathode copper is not uniform. The closer the position at the surface of the cathode copper to the jet region, the flatter the surface of the cathode copper, and vice versa.
- In the single-side jet inlet mode, when the jet position is at the middle height of the cathode deposition zone, the cathode quality is the best.
