Description
Известные способы очистки никелевого электролита экстракцией от т желых металлов сложиы, продолжительны и не обеспечивают достаточно полного отделени примесей.The known methods for the purification of nickel electrolyte by extraction from heavy metals are complex, long and do not provide a sufficiently complete separation of impurities.
Описываемый способ позвол ет повысить эффективность очистки электролита от меди и железа, ускорить процесс и упростить те.чнологию . Достигаетс это тем, что исходный никелевый электролит обрабатывают никелевыми сол ми Жирных кислот фракций Сю-Cie, малорастворимых в электролите.The described method allows to increase the efficiency of electrolyte cleaning from copper and iron, speed up the process and simplify the technology. This is achieved by the fact that the initial nickel electrolyte is treated with nickel salts of Fatty acids of the Xyu-Cie fractions, which are poorly soluble in the electrolyte.
Обработку электролита осуществл ют в противоточных экстракционных колоннах, причем электролит предварительно окисл ют воздухом дл перевода солей двухвалентного железа в соли трехвалентного железа . Экстрагентом вл етс раствор никелевых солей жирных кислот в этих кислотах фракций Сю-CieОбразуюидийс омыленный продукт, содержащий железо и медь, после отделени от электролита обрабатываетс серной кислотой дл реэкстрагировани железа и меди, а затем содой-дл регенерации жирных кислот, которые возвращают дл повторного использовани после дополнительной обработки сульфатом никел в присутствии соды.The electrolyte is treated in countercurrent extraction columns, the electrolyte being pre-oxidized with air to convert ferrous iron salts to ferric salts. The extractant is a solution of nickel salts of fatty acids in these acids of the fractions. Xyu-Cie. The saponified iron and copper containing product, after separation from the electrolyte, is treated with sulfuric acid to extract iron and copper, and then with soda to regenerate the fatty acids, which are returned for reuse. after additional treatment with nickel sulfate in the presence of soda.
Реэкстрагирование железа и меди можно осуществл ть в одну и две стадии. В последнем случае сначала отдел етс сульфатный раствор меди, из которого медь выдел ют известными способами, например, электролизом с нерастворимыми анодами. Затем реэкстрагируетс железо , причем образующийс раствор сульфата железа направл ют в отвал.Extraction of iron and copper can be carried out in one and two stages. In the latter case, the copper sulfate solution is first separated, from which copper is isolated by known methods, for example, by electrolysis with insoluble anodes. The iron is then reextracted, and the resulting iron sulphate solution is sent to the dump.
Электролит после очистки его от железа и меди обрабатывают известными способами, например, газообразным хлором или анодным окислением, с целью удалени кобальта. После этого электролит считаетс полностью очищенным и возвращаетс дл повторного использовани .After cleaning it from iron and copper, the electrolyte is treated by known methods, for example, with chlorine gas or anodic oxidation, in order to remove cobalt. Thereafter, the electrolyte is considered fully purified and returned for reuse.
vN 142029 2 Предмет изобретени vN 142029 2 Subject of the invention
Способ очистки никелевого электролита от т желых металлов экстракцией ,: о и ч а ю ш, ийс тем,, что, с целью повышени эффективности очистки электролита от железа и меди, исходный никелевый электролит обрабатыйанэт никелевыми сол ми жирных кислот фракции Сю-С16,. .The method of purification of nickel electrolyte from heavy metals by extraction is: o and h and y w, yys so that, in order to increase the efficiency of electrolyte purification from iron and copper, the initial nickel electrolyte is treated with nickel salts of fatty acids of the Su-C16 fraction. .
