(Problem) Provided is 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 stress on the environment. (Means of resolution) A selective recovery method for rare metals which comprises the following process (1) and process (2) : (1) a process wherein 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 a metal compound is formed in an aqueous solution containing the metal component comprising the rare metal, and (2) a process wherein the solid phase resulting from the adsorption or storage of the metal component comprising the rare metal, obtained in process (1), is brought into contact with an aqueous solution containing a peroxy compound.
