Zusammenfassung:	The invention relates to a method for recovering valuable metals from a waste plastic plating layer containing copper and nickel. The method comprises the following steps of: (1) crushing the waste plastic plating layer containing the copper and the nickel into scraps; (2) leaching the scraps with stirring by using an acid solution; and (3) after leaching, standing until the leached dregs are precipitated, removing plastics floated on leachate, and filtering the leached dregs and the leachate for separation, wherein after the waste plastic plating layer containing the copper and the nickel istreated, the nickel is contained in the leachate, and the copper is contained in the leached dregs. Copper and nickel intermediate products obtained by the method are high in recovery rates, a subsequent treatment process is flexible and simple, and the method is novel and high in practicality.
