Series of laboratory laundering experiments on saturated anion-exchange resin selected in the enterprise on model solutions (distilled water and sulfuric acid) were done under this work. Pilot tests were conducted in CJSC "Dalur" to obtain uranium concentrate from saturated anion exchange resin AMP desorption eluates after impurities washing. The partially neutralized trademark regenerate and the common regenerate were used to wash the resin. The prewashing efficiency of anion exchanger from impurities was evaluated and technological regulations was developed to obtain finished product on the intermediate standard.
