Description
Изобретение относитс к экстракционным способам извлечение металлов и может найти применение в цветной металлургии дл очистки сульфатных растворов от железа .The invention relates to extraction methods for the extraction of metals and may find application in non-ferrous metallurgy for the purification of sulfate solutions from iron.
Цель изобретени - повышение степени очистки от железа (II).The purpose of the invention is to increase the degree of purification from iron (II).
Пример. Исходный раствор с содержанием , г/дм3: 8,011 Zn; 13,52 Cd; 0,265 Со; 0,316 Ni; 0,085 Fe и рН 4-5 смешивают с диэтиловым эфиром фталевой кислоты в объемном соотношении соответственно (1/3-3):1. Смесь встр хивают в течение 20 мин при температуре 20-50°С. Органическую и водную фазы раздел ют, водную фазу анализируют на содержание металлов. По данным анализов рассчитывают извлечение металлов в органическую фазу. Результаты экспериментов приведены в таблице. Приведенные в таблице данные свидетельствуют о том, что по сравнению с прототипом данный способ позвол ет в 2-10 раз снизить содержание железа в сульфатных растворах не затронув при этом цветные металлы.Example. Stock solution with a content of, g / dm3: 8.011 Zn; 13.52 Cd; 0.265 Co; 0.316 Ni; 0.085 Fe and pH 4-5 are mixed with phthalic acid diethyl ester in a volume ratio of respectively (1 / 3-3): 1. The mixture was shaken for 20 minutes at a temperature of 20-50 ° C. The organic and aqueous phases are separated; the aqueous phase is analyzed for metal content. According to the analysis, the extraction of metals into the organic phase is calculated. The experimental results are shown in the table. The data in the table indicate that, compared with the prototype, this method allows to reduce the iron content in sulfate solutions by 2-10 times without affecting non-ferrous metals.
