Description

technical field [0001] The invention relates to the field of chemistry, in particular to an electrolysis system device and a method for electrolytic copper. Background technique [0002] The traditional electrowinning technology is to place the cathode and anode in a slow-flowing or stagnant electrolytic cell. Under the action of an electric field, metal ions move toward the cathode in a directional manner, and electrons are obtained at the cathode to deposit and precipitate metal products. When the concentration of the target metal ion is low, the traditional electrowinning technology is prone to the concentration polarization of the cathode, causing a small amount of impurity ions to precipitate on the cathode together with the target metal ion, resulting in a serious decline in the quality of the cathode product, and the concentration difference Polarization leads to a decrease in electrolysis rate and an increase in recycling costs. [0003] In addition, there is a swir...

AI Technical Summary

Problems solved by technology

[0004] While the electrolysis process reduces and recovers metal products at the cathode, oxygen will be generated in the anode area, and the dissolved oxygen in the electrolyte will migrate to the surface of the cathode, oxidizing the electrolytically reduced metal, especially the centrifugal effect of the swirl electrolysis process, which will lead to Oxygen is enriched in the cathode area, which leads to the oxidation of electrolyzed metal products, inhibits electrolysis, and leads to low electrolysis efficiency

[0005] In the process of electrolysis, the concentration of metal ions will be lower and lower. Constant current density electrolysis will lead to the deterioration of the densification of the cathode metal, the increase of side reactions of hydrogen production by electrolysis, and the rapid swirling speed of the metal-containing waste liquid will produce anti-dissolution effect on the cathode. The overall performance is that the electrolysis efficiency decreases and the quality of cathode metal products decreases
