PROCESS FOR IMPROVING THE FORMATION OF HYDROUS ALUMINA DISPERSED WITHIN A WEAK BASE ANION EXCHANGE RESIN AND USE OF THE COMPOSITE PREPARED FOR THE RECOVERY OF LI+ FROM BRINE

摘要

Formation of additional hydrous alumina in the reticules of a weak-base anion-exchange resin, where AlCl3 has been precipitated as hydrous alumina by addition of ammonia, is achieved by subsequent treatment with HCl or NH4Cl and HCl to convert the resin to the chloride form, thus increasing the reticular volume of the resin.
