There is provided an electrowinning process for non-ferrous metals, which can inexpensively and stably recover a non-ferrous metal, such as zinc or copper, containing a very small quantity of lead for a long period of time by electrowinning. In a method for recovering a non-ferrous metal, such as zinc or copper, from an electrolytic solution containing a sulfate of the non-ferrous metal using an anode containing lead, a strontium containing solution prepared by dissolving strontium in concentrated sulfuric acid is added to the electrolytic solution to recover the non-ferrous metal from the electrolytic solution by electrowinning using the anode, the surface of the anode to be soaked in the electrolytic solution being blasted. |
