Ion exchange process for the recovery of uranium
Patent
·
OSTI ID:6511939
An ion exchange process for the recovery of uranium from a pregnant lixiviant employed in uranium leaching operations in which the lixiviant contains chloride ions inhibiting the adsorption of uranyl ions. The ion exchange resin employed to adsorb uranium from the lixiviant has cationic adsorption sites provided by quaternary ammonium groups having a hydroxyalkyl group as a quaternizing substituent. Through the use of a resin of this type, the resin loading in the presence of chloride ions is materially increased.
