The uranium sorption by anion exchange resins from productive solutions prepared by carbonate leaching from peat ore was investigated. The uranium recovery from leach liquors decreased during long-time exploitation of ion exchangers due to contamination of resins with humic substances. The alkaline solution of sodium chloride can be used to efficiently regenerate resins. The resin Purolite A660/4759 had the highest value of full dynamic exchange capacity, which was (36.62 ± 1.10) g U/L of wet settled resin. The desorption process was carried out by ammonium carbonate/bicarbonate mixture solutions with values of uranium recovery degree of (97.41 ± 2.53)%. The degree of uranium precipitation during crystallization of ammonium uranyl carbonate from pregnant solutions was 72%.
