Abstract
Description
Изобретение относится к металлургии, а именно к гидрометаллургическим способам извлечения никеля из окисленных руд.The invention relates to metallurgy, and in particular to hydrometallurgical methods for the extraction of nickel from oxidized ores.
В качестве прототипа выбран способ получения никеля и кобальта из силикатных руд (патент RU 2161658), включающий обжиг руды с последующим выщелачиванием обожженной руды раствором серной кислоты.As a prototype, a method for producing nickel and cobalt from silicate ores (patent RU 2161658) was selected, which includes roasting the ore, followed by leaching of the calcined ore with a solution of sulfuric acid.
Недостатком способа является относительно невысокое извлечение никеля из руды и высокий расход реагентов.The disadvantage of this method is the relatively low extraction of Nickel from ore and a high consumption of reagents.
Задачами, на решение которых направлено заявленное изобретение, являются повышение извлечения никеля и снижение расхода реагентов.The problems to which the claimed invention is directed are to increase the extraction of nickel and reduce the consumption of reagents.
Указанная задача решается тем, что в способе извлечения никеля из окисленных руд, включающем обжиг руды и последующее выщелачивание никеля раствором серной кислоты, выщелачивание никеля ведут при рН 1,0-2,0 в присутствии анионита.This problem is solved in that in a method for extracting nickel from oxidized ores, including roasting the ore and subsequent leaching of nickel with a solution of sulfuric acid, leaching of nickel is carried out at a pH of 1.0-2.0 in the presence of anion exchange resin.
Способ осуществляли следующим образом.The method was carried out as follows.
Пример. Предлагаемый способ испытан в лабораторных условиях при выщелачивании проб никелевой руды Кунгурского месторождения.Example. The proposed method was tested in laboratory conditions when leaching samples of Nickel ore of the Kungursky deposit.
Руда содержала 0,84% никеля, 15,3% железа, 10,1% магния, 0,9% алюминия, 0,8% кальция, 0,2% марганца.The ore contained 0.84% nickel, 15.3% iron, 10.1% magnesium, 0.9% aluminum, 0.8% calcium, 0.2% manganese.
Руду подвергли обжигу при температуре 450°С и после охлаждения измельчили до - 0,15 мм. Измельченную руду выщелачивали раствором серной кислоты с рН 1,0 - 2,0 в присутствии ионита Dowex М-4195.The ore was calcined at a temperature of 450 ° C and, after cooling, it was crushed to 0.15 mm. The crushed ore was leached with a solution of sulfuric acid with a pH of 1.0 - 2.0 in the presence of Dowex M-4195 ion exchanger.
После контакта в 5 стадий ионит и пульпу разделяли, причем насыщенный ионит выводили с первой стадии, пульпу без никеля с пятой стадии. Контакт вели в стаканах емкостью 2 л. Время контакта на каждой стадии - 4 часа, Т:Ж=1:3.After contact in 5 stages, the ion exchanger and pulp were separated, and the saturated ion exchanger was removed from the first stage, the nickel-free pulp from the fifth stage. Contact was made in 2 liter glasses. The contact time at each stage is 4 hours, T: W = 1: 3.
Результаты исследований по сравнению с прототипом приведены в табл.1. Здесь же даны результаты осуществления способа при запредельных значениях параметров. Снижение рН ниже 1,0 ведет к увеличению расхода кислоты, снижению емкости насыщения ионита без увеличения извлечения никеля из руды. При выщелачивании никеля при рН более 2,0 значительно снижается извлечение никеля из руды, а также время выщелачивания.The research results compared with the prototype are shown in table 1. The results of the method implementation are also given for the transcendental values of the parameters. Lowering the pH below 1.0 leads to an increase in acid consumption, a decrease in the capacity of saturation of the ion exchanger without increasing the extraction of nickel from the ore. When nickel is leached at a pH of more than 2.0, nickel recovery from ore is significantly reduced, as well as leaching time.
Из таблицы видно, что осуществление извлечения никеля из окисленных руд по заявляемому способу позволяет повысить извлечение никеля из руды на 5,6-8,3%, снизить затраты на расход реагентов.The table shows that the implementation of the extraction of Nickel from oxidized ores by the present method can increase the extraction of Nickel from ore by 5.6-8.3%, reduce the cost of reagent consumption.
При работе по заявляемому способу при запредельных значениях снижается извлечение никеля из руды, увеличиваются затраты на химреагенты When working according to the present method, with exorbitant values, the extraction of nickel from ore decreases, the cost of chemicals increases
