PROBLEM TO BE SOLVED : To provide a metal recovering method, which reduces the amount of use of a chemical used for the recovery treatment, makes the amount of generation of a waste small, and is economically executed, even when recovering a rare metal from a large amount of metal dissolution liquid. SOLUTION : The metal recovering method includes : a metal ion adsorbing step 3 of recovering metal ions by adsorbing the metal ions in metal dissolution liquid 1 to a metal ion adsorbent 2; a metal ion eluting step 6 of eluting, with an eluent 5, the metal ions adsorbed to a metal ion adsorbent 2; an electrolyzing step 8 of recovering a metal by electrolyzing the eluent 5 containing the metal ions; and an eluent collecting step 10 of collecting the eluent 5 from which a metal component is recovered.
