Sustainable Mining and Metallurgy

Copper electrolytic refining is an important technical link in the copper industry chain that determines the quality and performance of copper products. The principle, research progress and existing problems of cathode copper electrolytic refining technology such as traditional electrolytic refining method, permanent stainless steel cathode method, periodic reverse current method, pulsed current method, parallel flow electrolytic refining method, external field enhanced electrolytic refining method and high purity copper electrolytic refining technology prepared by single step or multiple step electrolytic refining were summarized and analyzed . The copper electrolytic refining technology was prospected, and it was pointed out that the cathode copper electrolytic technology would develop in the direction of strong adaptability of raw materials, high metal recovery rate, low production cost and energy consumption, and environmental friendliness,and the electrolytic refining technology of high purity copper is developing towards the direction of process simplification, energy saving and emission reduction, large scale production and high purification of products.
