<p>Process for the extraction and purification of the gallium contained in an industrial solution of sodium aluminate by fixing the gallium on a stationary phase consisting of a porous adsorbent polystyrene resin impregnated with an extracting agent optionally in the presence of a surface-active agent. After elution of the gallium in acidic medium, the resulting gallium salt is purified and concentrated to be directly reduced to the state of gallium metal of high purity, by electrolysis. …<IMAGE>… </p> |
