ABSTRACT OF THE DISCLOSURE Gallium contained in a solution, especially a strongly basic aqueous solution, can be effectively recovered by the following procedure. The solution is contacted with a chelate resin having (A) an =NOH group and (B) a functional group capable of forming a chelate bond with the functional group (A) through gallium or a chelate resin having a metal salt of the functional group. In this way, gallium is adsorbed to the resin.
