Abstract:Aiming at the high tenor of uranium in the adsorption barren liquor and eluated resin in the ion exchange area of Husab uranium mine in Namibia, laboratory experiments were carried out using strong basic anion resin LXA800. The influence of pH value of the pregnant leach solution on resin adsorption, the influence of adsorption upflow velocity, the influence of uranium tenor of the pregnant leach solution on resin adsorption, the influence of the impurities Fe and Cl in the pregnant leach solution on resin adsorption were studied. Subsequently, a pilot test was carried out to study the resin adsorption fluidization and the availability of the current resin was verified by several cycles of adsorption and elution tests.
