PROBLEM TO BE SOLVED: To provide a method for sorting/recovering metallic compounds easily from fly ash.

SOLUTION: This method comprises the steps of: passing a mixture of finely powdered incineration ash with water through a unipolar magnetic field while mixing/agitating the aqueous mixture; passing the aqueous mixture through another unipolar magnetic field having the polarity different from that of the preceding unipolar magnetic field; attracting/sorting out a magnetic metallic compound from the aqueous mixture by a permanent magnet; and sorting out a nonmagnetic metallic compound from the aqueous mixture by specific gravity.
