Beschreibung
Zusammenfassung:	FIELD: rare metal technology. ^ SUBSTANCE: method comprises leaching of initial material in sulfuric acid aqueous solution to produce solution and solid precipitate, said leaching conducted in presence of sulfate of metal having higher positive oxidation potential than that of aluminum. Solution obtained is treated with complexing ampholite with benzyliminodiacetate groups and thus recovered gallium is then concentrated. ^ EFFECT: increased degree of gallium recovery into solution and reduced consumption of sulfuric acid. ^ 4 cl, 3 tbl, 3 ex
