The experimental-industrial study results of the process of sorption of rare-earth elements on sulfonic cation-exchange resin KU-2-8 from nitrate solutions of loparite concentrate development are presented. Values of different obtained elements are discussed. Different changes in processes are described. Reprocessing loparine raw materials in the close cycle without hydrochloric and sulfuric acid, and excess of normative sodium content in productional concentrate is possible. Keywords: ionite, sorption, loparite concentrate, rare-earth element, thorium.
