REJUVENATION OF THE ANION EXCHANGER USED FOR URANIUM RECOVERY

摘要

REJUVENATION OF THE ANION EXCHANGER USED FOR URANIUM RECOVERY A process is described for restoring and maintaining the total ion exchange capacity of the resin used for uranium recovery in in situ uranium leaching. The used resin of lowered exchange capacity is treated with a solution containing Na2CO3 or NaHCO3, or admixtures thereof. The process preferably is used in conjunction with acid elution of the uranium from the resin.
