Abstract
Description
Изобретение относится к металлургии, а именно к способам получения цветных металлов.The invention relates to metallurgy, and in particular to methods for producing non-ferrous metals.
В качестве прототипа выбран способ извлечения цветных металлов из руд, включающий разработку рудного пласта путем гидроразмыва с получением пульпы и извлечением из твердой фазы пульпы цветных металлов, последующее подземное выщелачивание рудного тела раствором кислоты, сбор и переработку полученного продуктивного раствора (Кучное и подземное выщелачивание металлов, под ред. С.Н.Волощука, М., Недра, 1982, с.37-44).As a prototype, a method for extracting non-ferrous metals from ores was selected, including the development of an ore formation by hydraulic washing to obtain pulp and extracting non-ferrous metals from the pulp solid phase, subsequent underground leaching of the ore body with an acid solution, collection and processing of the resulting productive solution (Heap and underground metal leaching, under the editorship of S.N. Voloshchuk, M., Nedra, 1982, p. 37-44).
Недостатком способа является недостаточно высокая степень извлечения металлов. Задачей, на решение которой направлено заявленное изобретение, является повышение степени извлечения металлов.The disadvantage of this method is not a sufficiently high degree of metal extraction. The task to which the claimed invention is directed is to increase the degree of metal extraction.
Указанная задача решается тем, что в способе извлечения никеля из руд, включающем разработку рудного пласта путем гидроразмыва с получением пульпы и извлечением из твердой фазы пульпы цветных металлов, последующее подземное выщелачивание рудного тела раствором серной кислоты, сбор и переработку полученного продуктивного раствора, гидроразмыв рудного пласта осуществляют до уровня, превышающего уровень грунтовых вод не менее чем на 1 метр, с использованием жидкой фазы пульпы гидроразмыва.This problem is solved in that in a method for extracting nickel from ores, including the development of an ore formation by hydraulic washing to obtain pulp and extracting non-ferrous metals from the solid phase of the pulp, subsequent underground leaching of the ore body with a solution of sulfuric acid, collection and processing of the resulting productive solution, hydraulic washing of the ore formation carried out to a level exceeding the level of groundwater by at least 1 meter, using the liquid phase of the hydraulic wash pulp.
То, что разработку рудного пласта ведут путем гидроразмыва позволяет оставлять в зоне выщелачивания микрочастицы цветных металлов.The fact that the development of the ore formation is carried out by hydraulic washing allows you to leave microparticles of non-ferrous metals in the leach zone.
То, что добычу полезного ископаемого ведут до достижения не менее 1 м над уровнем грунтовых вод обеспечивает эффективность горноподготовительных и добычных работ для метода подземного выщелачивания.The fact that mining is carried out until reaching at least 1 m above the groundwater level ensures the efficiency of mining and mining operations for the method of underground leaching.
При этом уровень грунтовых вод может быть технически понижен для обеспечения максимально возможной выемки полезного ископаемого.At the same time, the groundwater level can be technically reduced to ensure the maximum possible extraction of minerals.
Применение метода подземного выщелачивания позволяет эффективно доработать месторождения полезных ископаемых с доизвлечением трудноизвлекаемых запасов. Для добычи полезного ископаемого с поверхности могут использоваться как сухие, так и мокрые методы добычи, например гидроразмыв рудного тела.The use of the underground leaching method allows you to efficiently refine mineral deposits with the recovery of hard-to-recover reserves. Both dry and wet extraction methods, such as hydraulic erosion of the ore body, can be used to extract mineral from the surface.
Пример. Предлагаемый способ испытан в полупромышленных условиях на Кунгурском месторождении окисленных никелевых руд. На опытной ячейке размером 10×20 м осуществили добычу никелевой руды путем гидроразмыва пласта, полученную пульпу направляли на разделение путем отстоя.Example. The proposed method was tested in semi-industrial conditions at the Kungursky deposit of oxidized nickel ores. Nickel ore was mined by hydraulic formation erosion in a test cell measuring 10 × 20 m; the resulting pulp was sent for separation by sedimentation.
Твердую фазу руды обезвоживали и направляли на опытную установку по пиро- и гидрометаллургическому извлечению никеля известными способами. Жидкую фазу собирали в отстойник и использовали для размыва рудного пласта гидромониторами.The solid phase of the ore was dehydrated and sent to a pilot plant for pyro- and hydrometallurgical extraction of nickel by known methods. The liquid phase was collected in a sump and used for erosion of the ore formation by hydraulic monitors.
После разработки рудного пласта до глубины 10 м (5 м над уровнем грунтовых вод) площадку подготовили для подземного выщелачивания никеля из магнезиальной руды на месте залегания.After the development of the ore bed to a depth of 10 m (5 m above the groundwater level), the site was prepared for the underground leaching of nickel from magnesia ore at the site of occurrence.
Для этого на площадке были оборудованы горные выработки для подачи раствора серной кислоты 50-100 г/л в недра - как канавы на поверхности, так и закачные скважины для подачи растворов на глубину до 30-60 м от поверхности площадки. Проведенный опыт позволил извлечь 90% никеля из руды, поднятой на поверхность, и 75% никеля из руды на месте ее залегания.For this purpose, mine workings were equipped at the site for supplying a solution of sulfuric acid of 50-100 g / l to the bowels - both ditches on the surface and injection wells for supplying solutions to a depth of 30-60 m from the surface of the site. The experiment made it possible to extract 90% of nickel from ore raised to the surface and 75% of nickel from ore at its location.
Совмещение двух методов добычи и переработки руды дает возможность извлечь до 85% никеля из бедных руд (0,5-0,8% никеля) при минимальных капитальных и эксплуатационных расходах.The combination of the two methods of ore mining and processing makes it possible to extract up to 85% nickel from poor ores (0.5-0.8% nickel) with minimal capital and operating costs.
