The present invention relates to a method for electrolytic treatment of a metal-containing solution, wherein at least one nonionic surfactant is used in the electrolytic solution, and the surfactant is diluted with water in a ratio of 1:10, 190 g of sulfuric acid. The surface tension of an electrolytic solution having a surfactant concentration of 0.2% by weight at a temperature of 24 ° C. in an aqueous solution with / l and copper sulfate 157 g / l is reduced by 20-60% by weight. The method of the present invention is suitable for obtaining or refining metals such as copper, chromium, nickel, zinc, gold and silver. |
