A process for the electrolytic treatment of metal-containing solutions, wherein at least one nonionic surfactant is used in the electrolyte solution, the surfactant reducing the surface tension of the electrolyte solution at a surfactant concentration of 0.2% by weight and a temperature of 24° C. in an aqueous solution with 190 g/l of sulfuric acid and 157 g/l of copper sulfate, which is diluted with water in a ratio of 1:10, by from 20 to 60%, is useful for working up ores or the purification of metals, like copper, chromium, nickel, zinc, gold and silver. |
