Abstract
Description
Изобретение относится к металлургии, а именно к гидрометаллургическим способам получения никеля.The invention relates to metallurgy, and in particular to hydrometallurgical methods for producing nickel.
В качестве прототипа выбран способ извлечения никеля из растворов или пульп выщелачивания руд (патент RU 2287597), включающий сорбцию никеля на ионите с последующей десорбцией никеля раствором кислоты и переработку десорбата.As a prototype, a method for extracting nickel from solutions or ore leach pulps (patent RU 2287597) was selected, including sorption of nickel on ion exchange resin followed by desorption of nickel with an acid solution and processing of the desorbate.
Недостатком способа является невысокое извлечение никеля в десорбате, так как медь, оседая на ионите, снижает его емкость.The disadvantage of this method is the low extraction of Nickel in the desorbate, as copper, deposited on the ion exchanger, reduces its capacity.
Задачей, на решение которых направлено заявленное изобретение, является повышение извлечения никеля.The challenge to which the claimed invention is directed is to increase nickel recovery.
Указанная задача решается тем, что в способе извлечения никеля из растворов и пульп, включающем выщелачивание и сорбцию никеля на ионите с последующей десорбцией раствором кислоты и переработку десорбата, после десорбции никеля с ионита раствором аммиака с ионита снимают медь.This problem is solved by the fact that in the method for extracting nickel from solutions and pulps, including leaching and sorption of nickel on an ion exchange resin followed by desorption with an acid solution and processing of the desorbate, after desorption of nickel from the ion exchange resin with ammonia solution, copper is removed from the ion exchange resin.
Пример. Предлагаемый способ испытан в лабораторных условиях при извлечении никеля из растворов кучного выщелачивания магнезиальных окисленных никелевых руд Рогожинского месторождения и из пульпы от выщелачивания железо-магнезиальной руды Рогожинского месторождения.Example. The proposed method was tested in laboratory conditions for the extraction of nickel from heap leaching solutions of magnesia oxidized nickel ores of the Rogozhinsky deposit and from pulp from leaching of iron-magnesian ore of the Rogozhinsky deposit.
Сорбцию из раствора вели в 2 последовательно соединенных стеклянных колонках диаметром 14 мм и высотой 1,5 м каждая.Sorption from the solution was carried out in 2 series-connected glass columns with a diameter of 14 mm and a height of 1.5 m each.
Сорбцию из пульпы осуществляли в 7 последовательно работающих стаканах объемом 2 л при контакте на стадии 1 час. Затем пульпу и ионит разделяли и передвигали навстречу друг другу, так что из 1 стакана выходил насыщенный ионит, из седьмого - обедненная по никелю пульпа.Sorption from the pulp was carried out in 7 sequentially working glasses with a volume of 2 l with contact at the stage of 1 hour. Then the pulp and the ion exchanger were separated and moved towards each other, so that saturated ion exchanger came out of 1 glass, and the pulp depleted in nickel came out of the seventh.
С насыщенного ионита Dowex М-4195 никель десорбировали раствором серной кислоты 160 г/л. Перед возвратом ионита на сорбцию с него в 2 последовательно соединенных стеклянных колонках диаметром 14 мм и высотой 1,5 м 5% раствором аммиака сняли медь.Nickel was stripped from a saturated Dowex M-4195 ion exchanger with a solution of sulfuric acid 160 g / L. Before returning the ion exchange resin to sorption, copper was removed from it in 2 series-connected glass columns with a diameter of 14 mm and a height of 1.5 m with a 5% ammonia solution.
Медьсодержащие растворы подкисляли, затем направляли на концентрирование на анионит ВП-1п. С насыщенного ионита меди десорбировали раствором 3% аммиака +10% сульфата аммония. Из полученных растворов с концентрацией меди 30-40 г/л путем упаривания получили товарный продукт - медный купорос CuSO4·5H2O.Copper-containing solutions were acidified, then sent for concentration to VP-1p anion exchange resin. From a saturated ion exchanger, copper was desorbed with a solution of 3% ammonia + 10% ammonium sulfate. From the obtained solutions with a copper concentration of 30–40 g / l by evaporation, a marketable product, copper sulfate CuSO 4 · 5H 2 O, was obtained.
Таким образом, существует возможность извлечения в товарный продукт кроме никеля еще и меди.Thus, it is possible to extract copper in addition to nickel in a marketable product.
Всего проведено три цикла сорбции - десорбции на ионите Dowex М-4195 из раствора и пульпы.In total, three sorption cycles were carried out — desorption on Dowex M-4195 ion exchanger from solution and pulp.
Результаты исследований по сравнению с прототипом приведены в табл.1.The research results compared with the prototype are shown in table 1.
Из табл.1 видно, что осуществление извлечения никеля из растворов и пульп по заявляемому способу позволяет повысить извлечение никеля, увеличить емкость насыщения по никелю и концентрацию никеля в десорбате, что уменьшает затраты на переработку десорбата с извлечением никеля в товарный продукт.From table 1 it is seen that the implementation of the extraction of Nickel from solutions and pulps by the present method allows to increase the extraction of Nickel, to increase the saturation capacity of Nickel and the concentration of Nickel in the desorbate, which reduces the cost of processing desorbate with the extraction of Nickel in a commercial product.
