PROBLEM TO BE SOLVED : To provide a recovery method for rare metals of a novel kind, which allows a specific metal component to be recovered with good selectivity from among rare metals, and which imposes little load on the environment. SOLUTION : The selective recovery method for rare metals includes the following steps (1) and (2) : a step (1) in which a metal component comprising a rare metal is adsorbed or stored in solid phase by means of a method in which an aqueous solution that contains the metal component comprising the rare metal is brought into contact with a chelating resin or an adsorption agent, or a method in which a precipitate of the metal compound is formed in the aqueous solution containing the metal component comprising the rare metal : and a step (2) in which the solid phase resulting from the adsorption or storage of the metal component including the rare metal, obtained in step (1), is brought into contact with the aqueous solution containing a peroxy compound.
