Abstract
A process for extracting and purifying the gallium contained in an industrial solution of sodium aluminate by fixing the gallium on a stationary phase constituted by porous polystyrene adsorbent resin which is impregnated with an extracting agent, optionally in the presence of a surface-active agent. After elution of the gallium in acid medium, the resultant gallium salt is purified and concentrated so as to be reduced directly to the state of high purity metallic gallium, by electrolysis.
