| Abstract: |
| Influences of electrolyte temperature (40?70 ℃), current density (200?320 A/m2), sulfuric acid concentration (110?230 g/L), cupric ion concentration (25?65 g/L), and electrode spacing (20?35 mm) on power consumption of copper electrorefining were investigated by single factor experiment. The results show that power consumption rises significantly with increase of current density and electrode spacing, and drops remarkably with rise of electrolyte temperature and sulfuric acid concentration. Upon rising of Cu2 concentration, power consumption drops sharply firstly and then tends to maintain stable, the minimum power consumption is obtained with Cu2 concentration of 55 g/L. |
