Изобретение относится к гидрометаллургии, в частности к способам десорбции сурьмы и комплексообразующих ионитов, и может быть использовано в технологии извлечения сурьмы из растворов электролитического рафинирования меди. The invention relates to hydrometallurgy, in particular to methods for the desorption of antimony and complexing ion exchangers, and can be used in the technology of extracting antimony from solutions of electrolytic refining of copper.
Целью изобретения является повышение степени извлечения сурьмы и удешевление процесса. The aim of the invention is to increase the degree of extraction of antimony and the cost of the process.
П р и м е р. В лабораторный реактор емкостью 3 л, снабженный дренажем, воздушной линией, обогреваемый глухим паром, помещают 0,5 л ионита. Ионит насыщают сурьмой путем пропускания через слой смолы 50 л медного электролита, содержащего, г/л: медь 45-53; серная кислота 110-140; сурьма 0,2-1,2. Десорбирующий раствор готовят в промежуточной емкости путем насыщения 1-8 н. технической серной кислоты поваренной солью с содержанием хлорида натрия 96-98% . Насыщенный сурьмой ионит заливают 2-6 объемами десорбирующего раствора с отношением концентраций соли к кислоте 0,33-5,09. Десорбцию ведут при температуре 20-80оС с периодичностью перемешивания 1-5 ч-1 при продолжительности акта перемешивания 1-5 мин и общей продолжительности процесса десорбции 1-7 ч. Температуру процесса в каждом конкретном случае рассчитывают, исходя из требуемой степени десорбции сурьмы по формуле
X1= - .PRI me R. 0.5 l of ion exchanger is placed in a laboratory reactor with a capacity of 3 l, equipped with a drain, an air line, heated with deaf steam. Ionite is saturated with antimony by passing through a resin layer 50 l of a copper electrolyte containing, g / l: copper 45-53; sulfuric acid 110-140; antimony 0.2-1.2. A desorption solution is prepared in an intermediate container by saturation of 1-8 N. technical sulfuric acid with sodium chloride content of 96-98%. Saturated antimony ion exchanger is poured with 2-6 volumes of a stripping solution with a ratio of salt to acid concentrations of 0.33-5.09. Desorption is carried out at a temperature of 20-80 ° C with stirring intervals of 1-5 h -1 with stirring act duration of 1-5 minutes and the total duration of the desorption process 1-7 hours. The temperature of the process in each case is calculated from the desired degree of stripping of antimony according to the formula
X 1 = - .
По окончании десорбции раствор отделяют через дренаж, анализируют на содержание сурьмы, рассчитывают фактическую степень десорбции. Сурьмяный элюат направляют на переработку и после извлечения сурьмы возвращают в оборот. Результаты по десорбции сурьмы представлены в таблице. At the end of the desorption, the solution is separated through the drainage, analyzed for the antimony content, and the actual degree of desorption is calculated. Antimony eluate is sent for processing and after the extraction of antimony is returned to circulation. Antimony desorption results are presented in the table.
Как видно из приведенных данных, предложенный способ эффективен, прост в осуществлении и обеспечивает по сравнению с прототипом повышение степени десорбции до 100 и удешевление технологического процесса. As can be seen from the above data, the proposed method is effective, simple to implement, and provides, compared with the prototype, an increase in the degree of desorption to 100 and a cheaper process.
Кроме того, в связи с отсутствием токсических испарений и загазованности рабочей площади улучшаются санитарно-гигиенические условия и упрощается технологический процесс. In addition, due to the absence of toxic fumes and gas contamination of the working area, sanitary conditions are improved and the process is simplified.
