Description
Изобретение относитс к гидрометаллур гни, в частности к регенерации сернсй кислоты из отработанных растворов с возвращением ее в основное производство.The invention relates to hydrometallic rot, in particular to the regeneration of sulfuric acid from waste solutions with its return to the main production.
Известны способы регенерации серной , дислоты с помощью экстракции ее органическим растворителем l. Так Примен ют в качестве экстрагента 0,1-0,5 М раствор сильно разветвленных третичных ами сйв в органическом разбавителе Амско 125-62 которые в СССР не производ тс .Known methods of regeneration of sulfuric, disloty using extraction with an organic solvent l. Thus, a 0.1–0.5 M solution of a highly branched tertiary amide in an organic diluent, Amsko 125–62, which is not produced in the USSR, is used as an extractant.
Известен также экстрагент дл звлечеви сернсЛ кислоты из отходов гпроиаводс ва двуокиси титана на основе третичных аминов и керосина с добавками высших спиртов С.-Сд 2.Серную кислоту вымывают из органической фазы водой с получением реэкстрактс«, годных дл повторного нспользовани . Особенностью этого экстрагента вл ютс длительное врем отстаивани эмульсии и заметна растворимость в водвой фазе высших спиртов .The extractant for sulfuric acid acids from the waste of titanium dioxide based on tertiary amines and kerosene with additions of higher alcohols C.-Cd 2. is also known. Sulfuric acid is washed from the organic phase with water to obtain reextractable for reuse. The peculiarity of this extractant is the long time it takes for the emulsion to settle and there is a noticeable solubility in the water phase of higher alcohols.
Цель изобретени - интенсификаци про .цесса, уменьшение потерь экстрагента, аThe purpose of the invention is to intensify the process, reduce the loss of the extractant, and
также возможность регенерации серной кис лоты из отходов медного производства.also the possibility of regeneration of sulfuric acid from copper production wastes.
Поставленна цель достигаетс применением в качестве, етсстрагента раствора третичных аминов в керосине с добавками алкилфенолов формулыR -ОН,This goal is achieved by using, as a strategic agent, a solution of tertiary amines in kerosene with the addition of alkylphenols of the formula R -OH,
где Я - алкилбензольный радикал Соотношение компонентов в экстрагевте следующее, об.%: . Третичный амин35-50where I - alkylbenzene radical The ratio of components in the extragave the following,%:. Tertiary amine35-50
Алкилфенол5-15Alkylphenol5-15

Алкил}юколы практически нерастворимы в воде, в отдельности в данных услови х ни сервую кислоту, ни примеси не экстрагируют , а в смеси с третичными аминами предупреждают образование третьей фазы и значительно уменьшают врем расслаивани фаз. Применение предлагаемого экстрагента позволит эффективно регенерирсжать серную кислоту из отходов, нагр зненных сол ми цветных металлов (содержание катионов-41римесей может доходить до 80 г/л)Alkyl} yukols are practically insoluble in water, separately under these conditions neither the serum acid nor the impurities are extracted, and in the mixture with tertiary amines they prevent the formation of the third phase and significantly reduce the phase separation time. The use of the proposed extractant will effectively regenerate sulfuric acid from waste that has been contaminated with salts of non-ferrous metals (the content of cations-41 mixtures can reach up to 80 g / l)
