description PROBLEM TO BE SOLVED: To provide a method for electrolytic extraction of a nonferrous metal, which enables the electrolytic extraction of the nonferrous metal having an extremely poor grade of lead, such as zinc and copper, steadily for a long period and at low cost.SOLUTION: In a method for electrolytic extraction of the nonferrous metal from an electrolytic solution containing a sulfuric acid salt of the nonferrous metal such as zinc and copper using a lead-containing anode, a strontium-containing solution prepared by dissolving strontium in concentrated sulfuric acid is added to the electrolytic solution, and the electrolytic extraction of the nonferrous metal is carried out using an anode of which a surface to be immersed in the electrolytic solution is blast-treated.
