The micro-dispersed gallium is enriched and recovered from the seed mother liquor of alumina production by the Bayer process by resin adsorption. The method is simple in process and has no special requirements for industrial production. The extraction of gallium has no other influence on the mother liquor except gallium. The mother liquor will not adversely affect alumina production, and at the same time, it will improve the purity of alumina.

Jiangsu Kingshan New Material Co., Ltd. provides gallium-extracting resin, which has large adsorption capacity, high mechanical strength, and convenient regeneration. It can effectively enrich and recover gallium in the mother liquor, thereby improving the purity of alumina.
