Abstract
Description
Изобретение относится к области гидрометаллургии цветных металлов и может быть использовано при переработке концентратов, промпродуктов и твердых отходов, содержащих металлы.The invention relates to the field of hydrometallurgy of non-ferrous metals and can be used in the processing of concentrates, industrial products and solid waste containing metals.
Известны способы обжига и выщелачивания [Г.М. Вольдман, А.Н. Зеликман. Теория гидрометаллургических процессов. М., Металлургия. 1993. С. 139-157] увеличением удельной поверхности выщелачиваемого материала, повышением концентрации реагента, снижением концентрации продукта, уменьшением эффективной толщины диффузного слоя, уменьшением толщины твердой оболочки, увеличением константы скорости реакции в автоклавах за счет термического и механического активирования.Known methods of firing and leaching [G.M. Voldman, A.N. Zelikman. Theory of hydrometallurgical processes. M., Metallurgy. 1993. S. 139-157] an increase in the specific surface of the leachable material, an increase in the concentration of the reagent, a decrease in the concentration of the product, a decrease in the effective thickness of the diffuse layer, a decrease in the thickness of the hard shell, and an increase in the reaction rate constant in autoclaves due to thermal and mechanical activation.
Недостатками способов является низкое извлечение и низкое качество полученных металлов.The disadvantages of the methods is the low extraction and low quality of the obtained metals.
Наиболее близким техническим решением является обжиг марганцевых конкреций диоксидом серы при 500-600°С [Дарьин А.А., Теляков Н.М. Исследование возможности переработки фосфорсодержащих железомарганцевых конкреций Финского залива Записки горного института. 2006. Т. 169. С. 113-116], позволяющий осуществить селективный переход в водорастворимую форму цветных металлов и марганца путем нейтрального выщелачивания огарка от обжига.The closest technical solution is the burning of manganese nodules with sulfur dioxide at 500-600 ° C [Daryin A.A., Telyakov N.M. Investigation of the possibility of processing phosphorus-containing ferromanganese nodules in the Gulf of Finland. Zapiski Mining Institute. 2006. T. 169. S. 113-116], which allows for the selective transition to the water-soluble form of non-ferrous metals and manganese by neutral leaching of the cinder from firing.
Недостатком способа является то, что не рассматривалась возможность использования для сульфатизирующего обжига кека, полученного после содового спекания и выщелачивания вольфрамового концентрата, олеум, позволяющего переход в водорастворимую форму цветных металлов, железа и марганца путем гидрохлорирования.The disadvantage of this method is that it was not considered the possibility of using sulfate firing cake obtained after soda sintering and leaching of tungsten concentrate, oleum, which allows the transition to a water-soluble form of non-ferrous metals, iron and manganese by hydrochlorination.
Задачей изобретения является создание эффективного способа более полного извлечения из кека, полученного после содового спекания и выщелачивания вольфрамового концентрата, в раствор Fe, Mn, Си, Ni, Со и сохранения в кеке после выщелачивания Mo, W, Nb, Та (фиг. 1).The objective of the invention is to provide an effective method for more complete extraction from cake obtained after soda sintering and leaching of tungsten concentrate into a solution of Fe, Mn, Cu, Ni, Co and storing Mo, W, Nb, Ta in the cake after leaching (Fig. 1) .
Технический результат, который может быть достигнут при осуществлении изобретения, заключается в интенсификации процесса выщелачивания и более полном извлечении в раствор металлов из материалов, их содержащих.The technical result that can be achieved by carrying out the invention is to intensify the leaching process and to more fully recover metals from the materials containing them in the solution.
Этот технический результат достигается тем, что в известном способе извлечения ионов металлов из кека, полученного после содового спекания и выщелачивания вольфрамового концентрата, включающем сульфатизирующий обжиг, который осуществляют олеумом при Ж:Т=1:1, t=250-300°С, τ=4 ч с последующим гидрохлорированием сульфатного спека 2 н раствором HCl, 240 г/л NaCl.This technical result is achieved in that in the known method for the extraction of metal ions from cake obtained after soda sintering and leaching of a tungsten concentrate, including sulfatizing firing, which is carried out by oleum at W: T = 1: 1, t = 250-300 ° C, τ = 4 hours, followed by hydrochlorination of sulfate cake with 2 N HCl, 240 g / L NaCl.
Сущность способа поясняется схемами 1-2 и табл. 1-5.The essence of the method is illustrated by schemes 1-2 and table. 1-5.
После разложения вольфрамовых концентратов путем спекания или сплавления с содой при температуре 800-850°С и последующего выщелачивания спека водой в кеке после выщелачивания остаются не растворившиеся соединения.After decomposition of tungsten concentrates by sintering or alloying with soda at a temperature of 800-850 ° C and subsequent leaching of cake to water in the cake after leaching, insoluble compounds remain.
В табл. 1 дан химический состав кека.In the table. 1 given the chemical composition of cake.
Из данных табл. 1 следует, что в кеке преобладают железо, кальций, кремний и марганец.From the data table. 1 it follows that in the cake iron, calcium, silicon and manganese predominate.
В табл. 2 дан фазовый состав кека, выполненный рентгенофрактометрическим методом.In the table. 2 shows the phase composition of the cake, performed by x-ray diffraction method.
После квартования химический анализ изучаемой пробы проведен атомно-абсорбционным спектроскопическим методом, результаты которого приведены в табл. 3.After quartering, a chemical analysis of the test sample was carried out by atomic absorption spectroscopic method, the results of which are given in table. 3.
Из табл. 3 видно, что проба кека отличается повышенным содержанием железа, кальция, кремния и марганца.From the table. Figure 3 shows that the cake sample is characterized by a high content of iron, calcium, silicon and manganese.
Таким образом, данные табл. 1 и 3 близки.Thus, the data table. 1 and 3 are close.
Пример конкретного выполнения способа.An example of a specific implementation of the method.
На фиг. 2 дана предлагаемая технологическая схема переработки кека. В табл. 4 и 5 даны материальные балансы по извлекаемым металлам в соответствии со схемой фиг. 2.In FIG. 2 shows the proposed flow chart for processing cake. In the table. 4 and 5 give material balances for recoverable metals in accordance with the scheme of FIG. 2.
