Abstract
Gallium and rare earth values are recovered from oxide mixtures thereof by acidulating/dissolving such admixtures in an acid medium, and then liquid/liquid extracting the resulting solution and ultimately recovering said values from the phases which separate. The subject process is advantageously applied, for example, to the recovery of gallium and gadolinium from the waste fines resulting from the production of the garnets Gd.sub.3 Ga.sub.5 O.sub.12.
