FIELD: metallurgy. SUBSTANCE: uranium from sulfuric acid solutions of underground leaching is sorbed with strongly basic anion-exchange resin AMP, desorbed with ammonium nitrate dissolved in sulfuric acid in cascade of countercurrent ion-exchange columns with exposure of ionite to electric field successively in each ion-exchange columns of desorption cascade with duration of exposure to electric field is determined by the time of attainment of chemical equilibrium in treated column and next one in desorption cascade. EFFECT: higher efficiency. 1 dwg
