Description
Изобретение относитс к способам очистки раствора сульфата никел , полученного из отработанных железо-никелевых аккумул торов .This invention relates to methods for purifying a nickel sulphate solution obtained from spent nickel-iron batteries.
Известен способ очистки раствора сульфата никел , полученного путем отмывки анодной массы железо-никелевых аккумул торов от щелочи водой и растворени ее в серной кислоте, от кальци и магни , состо щий в том, что из раствора выдел ют никель в виде карбонатов, которые затем обрабатывают серной кислотой.A known method for purifying a nickel sulphate solution obtained by washing the anodic mass of an iron-nickel battery from alkali with water and dissolving it in sulfuric acid from calcium and magnesium consists in removing nickel in the form of carbonates from the solution, which is then treated sulfuric acid.
С целью упрощени процесса и увеличени степени очистки раствора сульфата никел в предлагаемый раствор ввод т водорастворимый фторид с последующей нейтрализацией щелочью до рН 5-6, причем водорастворимый фторид можно нримен ть в 2,5-5-кратном количестве по сравнению с теоретически иеобходимым.In order to simplify the process and increase the degree of purification of the nickel sulphate solution, a water-soluble fluoride is introduced into the solution, followed by neutralization with alkali to pH 5-6, and water-soluble fluoride can be used in 2.5-5-fold amounts as compared to theoretically necessary.
Степень очистки раствора сульфата никел от кальци при этом составл ет 95- 97%, от магни 75-77%. Наличие в растворе железа, полуторных окислов и графита при нейтрализации раствора звеличивает степень его очистки.The degree of purification of nickel sulphate solution from calcium in this case is 95–97%, from magnesium 75–77%. The presence of iron, sesquioxides and graphite in the solution, when the solution is neutralized, exalts the degree of its purification.
С увеличением содержани железа до 1,85% Fe/Ni степень очистки раствора сульфата никел от кальци составл ет 99,5- 100%, от магни 87%.With an increase in the iron content up to 1.85% Fe / Ni, the degree of purification of the nickel sulphate solution from calcium is 99.5-100%, from magnesium 87%.
Очистку раствора от кальци и магни совмещают с очисткой этого же раствора от железа и полуторных окислов.Cleaning the solution from calcium and magnesium is combined with cleaning the same solution from iron and sesquioxides.
