Aiming at the problems of low resin saturation capacity and high tailing liquid content in the ion exchange adsorption process of a uranium ore leachate, an indoor ion exchange adsorption condition test was carried out by simulating the dense moving bed used in production. According to the nature of the ore and the selectivity of the resin, the effect of ion exchange was determined. The main factor of the adsorption process. This experiment mainly studied the effects of uranium concentration, pH, Fe3+ concentration and Cl- concentration on the resin adsorption effect. The test results show that the concentration of uranium in the leaching solution has a greater impact on the adsorption effect of the resin, while controlling the pH, Fe3+ concentration and Cl- concentration within a certain range has less impact on the adsorption. This study provides a basis for the control of uranium leaching and recovery, which is beneficial to reduce the concentration of uranium in the tail liquid, improve the adsorption effect, and ensure the effective connection and stable operation of each process.

In view of the problems such as low saturated capacity and high tail fluid content of resin in a uranium ore leaching liquid exchange adsorption process, the indoor ion exchange adsorption condition test was carried out by simulating the use of dense mobile bed, and the main factors affecting the ion exchange adsorption process were determined according to the properties of ore and resin selectivity. The effects of uranium concentration, pH, Fe3 plus concentration and Cl-concentration on resin adsorption were studied in this experiment. The test results show that the concentration of uranium in leachate has a great effect on the adsorption effect of resin, and the pH, Fe3 plus concentration and Cl-concentration control have less effect on adsorption in a certain range. Through this study, it provides a basis for uranium leaching recovery control, which is beneficial to reduce the concentration of tail liquid uranium, improve the adsorption effect, and ensure the effective convergence and stable operation of each process.

Aiming at the problems of low resin saturation capacity and high tailing content in ion exchange adsorption process of leaching solution of a uranium mine, the indoor ion exchange adsorption condition test was carried out by simulating the dense moving bed used in production. According to the ore properties and resin selectivity, the main factors affecting the ion exchange adsorption process were determined. This experiment mainly studied the influence of uranium concentration, pH, Fe3 + concentration and Cl - concentration on the adsorption effect of resin. The results show that the concentration of uranium in leaching solution has a great influence on the adsorption effect of resin, while the pH, Fe3 + concentration and Cl - concentration within a certain range have little influence on the adsorption effect. Through this study, the basis for uranium leaching recovery control is provided, which is conducive to reducing the uranium concentration in tail liquor, improving the adsorption effect, and ensuring the effective connection and stable operation of each process.<br>
