Abstrakt: A comparative study of rare earth, ferric and aluminum ions ion exchange behavior on gel sulfonated polystyrene cation exchange resins depending on the degree of the matrix cross-linking and pH of the solution is presented. Selective ion exchange of REEs is possible at the pH range of 1.5-2.0 using strongly acidic cation exchange resins containing more than 8% of DVB. The preliminary results of testing the efficiency of REEs recovery from the industrial uranium underground leaching solutions are also presented. [ABSTRACT FROM AUTHOR]
