摘要： The process of liquid-liquid extraction of gallium from sodium aluminate liquor used in the Bayer alumina process, uses an organic extractant comprising a diluent and a substituted hydroxyquinoline such that gallium and some aluminum are extracted into the organic phase.In five successive steps, the organic extractant solution loaded with gallium and aluminum is first contacted with an aqueous mineral acid solution, during which the acid solution strips the loaded solution of gallium and aluminum. Next, the phases are separated and a chloride salt or hydrochloric acid is dissolved in the acidic solution of gallium and aluminum which is then contacted with an organic solvent, e.g. n-butyl acetate. Aluminum remains in the aqueous acid solution whereas the organic solvent becomes loaded with gallium.After the phases have been separated, the organic solvent is separated from gallium chloride, which forms the feed for producing pure gallium.

The reaction temperature is lower than the temperature at which decomposition of the organometallic halide RMX begins and at least 10.degree. C. higher than the boiling point of the organic monohalide. The reaction may also take place in the presence of an organometallic derivative comprising a hydroxy group or an enolysable ketone group. The resulting organometallic halide may be used for the synthesis of anhydrous magnesium halide or for the reduction of titanium tetrachloride.

摘要： Highly pure (>99.99%) aqueous solutions of gallium chloride are obtained by a process having two major stages. The first stage, effected by passage of an aqueous acid solution containing gallium over a strongly basic ion exchange resin, makes it possible to eliminate an appreciable quantity of metal ions, such as Ca, Mg, Cr, V, Co, Zn and Pb, and further serves to concentrate the initial solution. In the second stage, the remaining ions, such as Al, Na and particularly Fe.sup.+++ are eliminated by a two-phase extraction with an organic extractant, preferably a C.sub.4 to C.sub.10 alcohol or a quaternary ammonium chloride.
