The impact of additives on the system during the electrolytic process of wet copper smelting
Thread Content
Additives are required in the electrolytic process of wet copper smelting. Please discuss the impact of electrolyte additives on the system.
Such a profound question. Haha. Thiourea, guar gum
For additives such as guar gum, 150 g/T.Cu is an appropriate amount; too much of it will cause the copper sheet to turn white and become brittle, while too little will result in excessive burrs on the sheet. In severe cases, sponge copper may form. Additionally, when too much of these additives is used in wet copper smelting, as they are organic polymers, it will increase the emulsification of the extractant
Copper electrolysis additives are generally solutions prepared by mixing bone glue, gelatin, and thiourea in certain proportions, and they are added to suppress the growth of dendrites in order to obtain smooth and even cathode plates. This is explained in detail in the book \"Modern Copper Metallurgy\"; it is recommended that the original poster read it
