Abstract:
The present disclosure describes a method for recovering metals such as gallium, indium and aluminum from III-V group compound semiconductors or semiconducting materials thereof containing arsenic, antimony and/or selenium. The method includes the step of adsorbing the arsenic, antimony and selenium selectively to an adsorbent containing the rare-earth metal compound with the use of the adsorbent.
