Gallium recovery resin from Bayer process mother liquor

At present, metal gallium is a by-product of alumina production, and the micro-dispersed gallium is enriched and recovered from the seed mother liquor of alumina produced by Bayer process by resin adsorption method. The method is simple and has no special requirements for industrial production. The extraction has no other influence on the mother liquor except for the gallium element, and the returned mother liquor does not adversely affect the alumina production, and at the same time, the purity of the alumina is increased.
