Abstract: The principle and method for the industrial controlling of copper electrolysis by means of the cathodic overpotential were described. The industrial results show that the cathodic overpotential is essential to the electrolyte characteristics. Through auto-control of cathodic overpotential, the optimum amount of additives can be determined, the stability of high pure cathodic can be raised by 6%, and the average current efficiency is raised by 1%.
Key words: copper electrolysis; additive; cathodic overpotenial; control
