Abstract: The present invention relates to a process for the recovery of gallium from Bayer process liquors. Bayer process liquor is obtained from alumina industries and contains 450 g/L Na2O, 80 g/L Al2O3 and 190null20 ppm of gallium. The present invention utilizes an organic and inorganic phase for a two stage separation process to recover gallium with high purity.
