Ion exchange process for the recovery of uranium
Creators
Description
In a method for the recovery of uranium from a pregnant lixiviant by contacting an anionic ion exchange resin with said lixiviant to adsorb uranium therefrom and wherein said lixiviant contains chloride ions which inhibit the adsorption of uranyl ions, the improvement comprising employing an anionic ion exchange resin having cationic adsorption sites provided by quarternary ammonium groups having a hydroxyalkyl group as a quarternizing substituent. Cationic adsorption sites may be provided by methylene hydroxyethyldimethylammonium groups
