Изобретение относитс к гидрометаллургии цветных металлов и может найти применение в ионообменной технологии переработки руд и концентратов, а также в процессах извлечени ценных компонентов и вредных примесей из технологических растворов и сбросных вод.The invention relates to hydrometallurgy of non-ferrous metals and can be used in ion-exchange technology for the processing of ores and concentrates, as well as in the processes of extracting valuable components and harmful impurities from technological solutions and waste water.
Известен способ извлечени цветных металлов из твердых материалов обработкой их полимерными азотсодержащими комплексообразующими соединени ми.A method is known for extracting non-ferrous metals from solid materials by treating them with polymeric nitrogen-containing complexing compounds.
По предложенному способу материал, например анионит АВ-17-8 в хлор-форме, обрабатывают 30%-ным водным раствором полиэтиленполиаминов, нейтрализованным ЗО%-ной сол ной кислотой до рН 7, при температуре 50°С. Это позвол ет селективно отдел ть примесные цветные металлы -от благородных.According to the proposed method, the material, for example AB-17-8 anion exchanger in the chlorine form, is treated with a 30% aqueous solution of polyethylene polyamines neutralized with ZO% hydrochloric acid to pH 7 at 50 ° C. This allows the selective separation of impurity non-ferrous metals from noble ones.
Пример. Анионит АВ-17-8 в хлорформе , содержащий (в вес. ч. на 1 вес. ч. сорбента) 0,019 золота; 0,026 меди и 0,021 цинка в виде цианистых комплексов, обрабатьшают в течение 6 час при 50°С и перемешивании раствором, содержащим Example. Anionite AB-17-8 in chloroform, containing (in weight parts by weight by weight of sorbent) 0.019 gold; 0.026 copper and 0.021 zinc in the form of cyanide complexes, are processed for 6 hours at 50 ° C and stirred with a solution containing
15 вес. ч. полиэтиленполиаминов, предварительно нейтрализованных 30%-ной сол ной кислотой до рН 7 и растворенных в 35 вес. ч. воды.15 wt. including polyethylene polyamines, previously neutralized with 30% hydrochloric acid to pH 7 and dissolved in 35 wt. h of water.
После обработки 1 вес. ч. анионита содержит 0,018 вес. ч. золота; 0,ОО05 вес ч.меди и О.ОООб вес.ч. цинка, т.е. с ионита десорбировано 98,1% меди, 97,1% цинк и линь 5% золота. Это свидетельствует о высокой селективности процесса по отношению к цианидам цветных металлов по сравнению с золотом.After processing 1 weight. including anion exchange resin contains 0,018 weight. h. gold; 0, OO05, weight of honey and O.OOOb weight.h. zinc, i.e. 98.1% of copper, 97.1% of zinc and lin of 5% of gold are desorbed from the ion exchanger. This indicates a high selectivity of the process with respect to non-ferrous cyanides in comparison with gold.
Предмет изобретени Subject invention
Способ извлечени цветных металлов из твердых материалов обработкой их полимерными азотсодержащими комплексообразующими соединени ми, о т л и ч а ющ и и с тем, что, с целью отделени примесных цветных металлов от благородных , например анионита АВ-17-8 в хлорформе , обрабатывают 30%-ным водным раствором полиэтиленполиаминов, нейтрализованным 30%-ной сол ной кислотой до рН 7, при температуре 50ОС.The method of extracting non-ferrous metals from solid materials by treating them with polymeric nitrogen-containing complexing compounds is necessary in order to separate non-ferrous non-ferrous metals from noble ones, such as anion-exchanger AB-17-8 in chloroform, 30 % aqueous solution of polyethylene polyamines, neutralized with 30% hydrochloric acid to pH 7, at a temperature of 50 ° C.
