    Abstract: A method is described for obtaining purified 68 Ga. The method comprises eluting 68 Ga from a sorbent in and/or on which are sorbed 68 Ga and 68 Ge, so as to generate a crude 68 Ga solution. The sorbent should have a higher affinity for 68 Ge than for 68 Ga. The crude 68 Ga solution is then applied to a medium cation exchange resin, and the resin is eluted with an aqueous alcohol so as to retain the 68 Ga on the resin and remove unwanted species from the resin. The resin is then eluted with an eluent, which may be an acidic solution, an alkaline solution or a solution of a species capable of complexing 68 Ga ions, so as to obtain an eluate comprising purified 68 Ga ions.

    Abstract: Process for separating and concentrating gallium from an aqueous solution containing gallium, together with aluminium, zinc and/or copper, characterized by the following combination of features: (a) preparation of a water-in-oil emulsion consisting of a neutral or alkaline aqueous phase and an organic phase containing an oil-soluble reactant in a homogenizer in a volume ratio of aqueous phase to organic phase of 2:2 to 3:2; (b) dispersion of the water-in-oil emulsion in the aqueous solution containing gallium, which is adjusted to at least 4 mol/l of HCl, in an extractor in a volume ratio of aqueous phase to water-in-oil emulsion of 30:1 to 10:1 until droplets of the water-in-oil emulsion with a diameter less than or equal to 1 mm are obtained; (c) separation of the water-in-oil emulsion from the aqueous continuum and splitting of the emulsion in a reactor with coaxial, double-insulated electrodes in a high-voltage kV/cm and a frequency greater than 50 Hz, the unsplit portion of the water-in-oil emulsion being recycled into step (b); (d) separation of the electrocoalesced organic phase of the water-in-oil emulsion in a gravity separator and recycling of the same into step (a).

    Abstract: Process for the liquid-liquid extraction of gallium from basic aqueous solutions, particularly sodium aluminate lye from alumina production according to the Bayer process, by means of an organic extraction agent comprised of a solvent and of substituted hydroxyquinoline, aluminium in addition to gallium being in the organic extraction agent solution. In five successive steps, the organic extraction agent solution containing gallium and aluminium is brought in substance exchange relationship with an aqueous mineral acid solution; the latter lades itself with gallium and aluminium and separates from the organic extraction agent solution. Chloride salt or hydrochloric acid is then dissolved into the solution laden with gallium and aluminium and is placed in substance exchange relationship with an organic solvent, for example an n-butyl acetate solution. The aluminium then remains in the aqueous acid solution while the organic solvent lades itself with gallium. After separation of the aqueous acid solution, the organic solvent is separated from the gallium chloride which is the starting product for the production of pure gallium. A main advantage of the present process is that, in the third step, the aqueous concentrated mineral acid laden with gallium and aluminium may be placed in substance exchange relationship with an organic solvent which, besides the fact that it is less costly, may be more gallium laden than substituted hydroxyquinoline.
