ABSTRACT:
Magnesium values are selectively recovered from salt brines, even salt brines which contain competing ions such as Li.sup.+, Ca.sup.++, and Sr.sup.++, by contacting the brine with an anion exchange resin which has dispersed therein a microcrystalline structure of the formula MgX.sub.2.2Al(OH).sub.3, where X is a halide.
