An improved process for the separation of uranium from the leached pulp of low grade uranium ore is reported using the resin-in-pulp method. For this study, four small pachucas were designed and calibrated. A series of tests were conducted batch-wise to determine the optimum conditions for uranium adsorption on a strong base anion exchange resin. The particle size of resin was 0.6–1.6 mm and the particle size of pulp was − 0.1 mm. Flow rates of resin and pulp were adjusted on 10 ml/h and 1 ml/h, respectively. The redox potential of pulp was 500 mV and the pH of pulp was 1.8. A McCabe Thiele diagram was constructed for the process and the experimental results confirmed the theoretical predictions. It is concluded that four stage counter-current resin-in-pulp operation under optimum conditions is sufficient to recover about 99% of the uranium from the leached ore.
