Description
Изобретение относитс к области гидрометаллургии редких и цветных металлов. M3iBecT6H способ извлечени металлов, например германи , с ионообменных омол десорбцией его 5-15% pacTiBopOM щелочи, из которой он может быть выделен известными опОСобами. Однако дл получени удовлетворительной степени десорбции Германи требуетс более 13 ст оеней десофбции. По предложенному опосо бу десорбцию щелочью Провод т Б присутствии (Гидроокиси металла, нерастворимой в щелочной среде, с последующей иейтрализащией суспензии -кислотой до рН 7-9. В качестве гидроокиси используют гидроокись магни , гид)роокись железа. Это интенсифицирует процесс. Способ заключаетс в следующем. Анионит АН-31, насыщенный германием и содержащий 0,20% ;германи , обрабатывают при перемещивании и от1ношении Т:Ж 1 :3 15%-1Ным раствором щелочи, IB которую ввод т раствор сульфата магни (50 г/л магни ) из расчета 10 г (магни иа 1 г десорбируемого Германи . Сульфат магни в щелочном растворе образует малорастворимую гидроокись. Вместо раствора соли на десорбцию можно подать отдельно приготовленную гидроокись магни или железа. Температура раствора 60° С. Врем перемещиваии 2 час. Содержание германи в отрегенерированном анионите 0,06%. Степень десорбции 73,6%. Германий, соосажденный на гидроокиси магни , представл ет собой бедный коицентрат, содержащий германи 1,07%. Степень десорбции 73,6%. Предмет изобретени 1.Способ сн ти металлов с ионообменных смол десорбцией раствором щелочи, отличающийс тем, что, с целью интенсификации процесса, десорбцию провод т IB присутствии гидроокиси .металла, нерастворимого в щелочной среде, с последующей нейтрализацией суспензии кислотой до рН 7-9. 2.Способ по п. I, отличающийс тем, что в качестве гидроокиси используют гидроокись магни , гидроокись железа.This invention relates to the field of hydrometallurgy of rare and non-ferrous metals. The M3iBecT6H is a method of extracting metals, for example germanium, from ion-exchange omol by desorption of its 5-15% pacTiBopOM alkali, from which it can be recovered by known opasi. However, to obtain a satisfactory degree of desorption of Germany, more than 13 tablespoons of desofibation are required. According to the proposed precipitation desorption with alkali, B is carried out by the presence of (Metal hydroxide insoluble in alkaline medium, followed by a neutralizing suspension, acid to pH 7-9. Iron hydroxide is used as hydroxide). This intensifies the process. The method is as follows. The anion exchanger AH-31, saturated with germanium and containing 0.20% germanium, is treated while moving and the ratio T: F 1: 3 is 15% with 1% alkali solution, IB of which is injected with magnesium sulfate solution (50 g / l magnesium) 10 g (magnesium 1 g of desorbed Germany. Magnesium sulphate in alkaline solution forms insoluble hydroxide. Instead of a salt solution, separately prepared magnesium or iron hydroxide can be supplied for desorption. Solution temperature is 60 ° C. Transfer time 2 hours. , 06%. The degree of desorb 73.6%. Germanium, co-precipitated on magnesium hydroxide, is a poor coicentrate containing 1.07% germanium. A desorption rate is 73.6%. that, in order to intensify the process, desorption is carried out by IB in the presence of an alkali metal hydroxide insoluble in an alkaline medium, followed by neutralization of the suspension with acid to a pH of 7-9. 2. A method according to claim 1, characterized in that magnesium hydroxide or iron hydroxide is used as the hydroxide.
