The method of dissolving hematite deposits intensification, containing cobalt radionuclides, on ion exchangers KU 2-8, modelling spent ion exchange resin, was proposed. Defined, that with direct current increasing and with acids concentration increasing, the efficiency of hematite deposits dissolution is increasing and could exceed 99%. The hematite dissolution accompanied by radionuclides secondary adsorption due to ion exchange that could be removed with sodium nitrate solution was presented.
