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 извлечение железа с последующей сорбцией никеля на ионите, десорбцией никеля с ионита и переработкой десорбата.As a prototype, a method for extracting nickel from solutions or ore leach pulps (patent RU 2287597) was selected, including iron extraction followed by sorption of nickel on the ion exchanger, desorption of nickel from the ion exchanger and processing of the desorbate.
Недостатком способа является невысокое извлечение никеля в десорбате.The disadvantage of this method is the low extraction of Nickel in the desorbate.
Задачей, на решение которой направлено заявленное изобретение, является повышение извлечения никеля.The problem to which the claimed invention is directed, is to increase the extraction of Nickel.
Указанная задача решаются тем, что в способе извлечения никеля из растворов или пульп выщелачивания руд, включающем извлечение железа с последующей сорбцией никеля на ионите, десорбцию никеля с ионита и переработку десорбата, перед сорбцией никеля извлекают железо и медь сначала осаждением при pH 2,5-3,0, а затем сорбцией железа и меди на отдельном ионите.This problem is solved by the fact that in the method for the extraction of nickel from solutions or pulps of leaching ores, including the extraction of iron followed by sorption of nickel on the ion exchanger, the desorption of nickel from the ion exchanger and the processing of the desorbate, iron and copper are first recovered by sorption at a pH of 2.5- 3.0, and then sorption of iron and copper on a separate ion exchanger.
Пример. Предлагаемый способ испытан в лабораторных условиях при выщелачивании кернового материала окисленных никелевых руд Кунгурского месторождения.Example. The proposed method was tested in laboratory conditions when leaching core material of oxidized nickel ores of the Kungursky deposit.
При содержании никеля в руде 0,76% руда содержала, %: 10,5 Fe, 18,3 Mg, 0,6 Al, 1,2 Ca, 0,5 Mn, 0,10 Cu.When the nickel content in the ore was 0.76%, the ore contained,%: 10.5 Fe, 18.3 Mg, 0.6 Al, 1.2 Ca, 0.5 Mn, 0.10 Cu.
Часть руды измельчили до - 10 мм и подвергли кучному выщелачиванию раствором серной кислоты 50-70 г/л с получением продуктивного никелевого раствора с элементами-примесями - магнием, алюминием, железом, кальцием, марганцем, медью.Part of the ore was ground to -10 mm and subjected to heap leaching with a solution of sulfuric acid of 50-70 g / l to obtain a productive nickel solution with impurities - magnesium, aluminum, iron, calcium, manganese, copper.
Часть руды измельчили до крупности - 0,2 мм и подвергли чановому сернокислотному выщелачиванию в стаканах при 90-95°С сернокислым раствором 100-120 г/л при Т:Ж=1:5 в пяти последовательно работающих стаканах в течение 3-х часов в каждом.Part of the ore was ground to a particle size of 0.2 mm and subjected to a channel sulfuric acid leaching in glasses at 90-95 ° C with a sulfuric acid solution of 100-120 g / l at T: W = 1: 5 in five successively working glasses for 3 hours in each.
По окончании контакта в течение 3-х часов твердое и жидкое перемещали противотоком, в итоге на выходе 1 стакана получали иловую фракцию пульпы с максимальной концентрацией никеля, на выходе 5 стакана - выщелоченную руду, которую после промывки складировали как кек выщелачивания.At the end of the contact, the solid and liquid were moved countercurrently for 3 hours, as a result, at the outlet of 1 cup, a sludge fraction of pulp with a maximum nickel concentration was obtained, at the exit of 5 cups, leached ore, which after washing was stored as leach cake.
Так переработали 3 кг руды.So processed 3 kg of ore.
Промытую воду от промывки кека выщелачивания направляли на 5-ю стадию выщелачивания.The washed water from washing the leach cake was sent to the 5th leaching stage.
Полученный никельсодержащий раствор от кучного выщелачивания и пульпу с содержанием Т:Ж=1:10 очищали от примеси железа известковым молоком при pH 2,5-3,0. Остатки железа и медь сорбировали на ионит. Очищенные от элементов-примесей раствор и пульпу направляли на сорбцию ионитом Dowex М-4195. Насыщенный ионит промывали водой, затем десорбировали никель раствором серной кислоты с концентрацией 150-180 г/л. Из полученного десорбата осаждали основной карбонат никеля.The resulting nickel-containing solution from heap leaching and pulp with a content of T: W = 1: 10 was purified from iron impurities with lime milk at a pH of 2.5-3.0. Residues of iron and copper were sorbed onto the ion exchanger. The solution and pulp purified from impurity elements were sent for sorption by Dowex M-4195 ion exchanger. Saturated ion exchange resin was washed with water, then nickel was stripped with a solution of sulfuric acid with a concentration of 150-180 g / l. From the obtained desorbate, basic nickel carbonate was precipitated.
Часть десорбата с концентрацией никеля 38,5 г/л в лабораторном электролизере переработали до выделения никелевого катода. Получен катодный никель марки ANC/A STM В 39-79.A portion of the desorbate with a nickel concentration of 38.5 g / l in the laboratory electrolyzer was processed to isolate the nickel cathode. Received cathode nickel brand ANC / A STM B 39-79.
Результаты исследований по сравнению с прототипом приведены в табл.The research results compared with the prototype are given in table.
Из таблицы видно, что осуществление извлечения никеля из растворов и пульп по заявляемому способу позволяет повысить извлечение никеля в десорбате в 1,9 раза, уменьшить затраты на переработку десорбата до готовых продуктов - основного карбоната никеля и катодного никеля на 30-33%.The table shows that the implementation of the extraction of Nickel from solutions and pulps by the present method can increase the extraction of Nickel in the desorbate 1.9 times, reduce the cost of processing desorbate to finished products - the main Nickel carbonate and cathode nickel by 30-33%.
