Кл.слова (ненормированные):
coal -- sorbents -- modification -- sorption isotherm -- sorbent capacity -- oleum
Аннотация: The data on accumulated mining waste in the territory of Kazakhstan are presented. Their processing has become very important in our time. The structure of surface-modified carbon materials with a grafted layer is given. New modified carbon sorbents were obtained, oleum was used as a modifying agent. It was revealed that the capacitive characteristics of the modified sorbent are significantly higher than that of the original one, which will make it possible to more efficiently extract the metal ion from wastewater and technogenic formations. Sorption is an effective method of extracting valuable components from wastewater and man-made formations. This method allows you to recover valuable substances with a high degree of wastewater treatment, which can be purified to the maximum permissible concentration of pollutants and then used in technological processes or in recycling water supply systems. Processing involves ores characterized by a low content of valuable components, fine dissemination and similar technological properties of minerals. The existing technologies for the development of minerals make it possible to use only a small part of the valuable mineral mass extracted from the subsoil, and the rest forms waste, which, as it accumulates and is stored, becomes one of the most significant factors of anthropogenic changes in the environment.

waste -- lead-zinc waste -- secondary raw materials -- non-ferrous metals -- valuable components -- waste processing -- waste disposal -- low-waste and non-waste technologies
Аннотация: The article presents the analysis and results of the study of technogenic slag waste of lead-zinc production. Slags of lead-zinc production contain a large number of toxic compounds: lead, zinc, osmium, cadmium, which are dangerous sources of environmental pollution. Due to the open storage of slags, it was found that the maximum permissible concentrations of lead were exceeded. Utilization of man-made slag waste is of great importance for reducing the negative impact on the safety of life and improving the environmental situation in the region. At the same time, slags are valuable raw materials containing compounds of non-ferrous and rare-earth metals.

Кл.слова (ненормированные):
техногенные отходы -- вторичное сырье -- цветные металлы -- утилизация отходов производства -- малоотходные и безотходные технологии
Аннотация: В статье представлены анализ и результаты научных исследований техногенных шлаковых отходов свинцового производства. После закрытия и ликвидации завода, оставшиеся отходы в виде шлаков являются источником экологического загрязнения почвы, грунтовых вод и воздуха. Шлаки свинцового производства содержат большое количество токсичных соединений, таких как свинец, цинк, осмий, кадмий, которые являются опасными источниками экологического загрязнения. Утилизация техногенных шлаковых отходов имеет большое значение для снижения отрицательного влияния на безопасность жизнедеятельности и улучшения экологической обстановки региона. В то же время шлаки являются ценным сырьем, содержащим соединения цветных и редкоземельных металлов. В статье показаны результаты лабораторных исследований шлаков по определению качественного и количественного состава ценных компонентов в отходах свинцового производства и возможности дальнейшей их переработки и утилизации. Были проведены исследования материала тяжелой фракции шлака на электронно-зондовом микроанализаторе марки JEOL IXA–8230 Electron Probe microanalyzer. Рентгенодифрактометрический анализ средней пробы шлака выполнен на дифрактометре ДРОН-4 с Cu –излучением, графитовый монохроматор. Из проб были выделены тяжелые фракции и изготовлены полированные искусственные аншлифы (брикеты). Аншлифы изучались под микроскопом марки LEICA DM 2500P и в иммерсионных жидкостях. По результатам исследований выявлено, что в свинцовых шлаках содержится достаточно высокое количество соединений цветных металлов: оксида свинца до 0,7 % и оксида цинка до 8,5 % от весового количества шлака, что позволяет сделать процесс утилизации токсичных отходов свинцового производства технически и экономически целесообразным

Development of technology for extraction of lead and zinc oxides from dust and slags during the utilization of lead plant waste. [Текст] / K. Zhantassov // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №2. - P. 81-85

Аннотация: The article proposes methods for the extraction of lead and zinc from slag waste and selects the optimal method for the selective extraction of zinc and lead oxides from dust and slags of lead production. The proposed technology of continuous carbon-free selective extraction of zinc and lead from the dust of electric steelmaking production allows the use of lead production slag, which is fed into a rotating drum furnace in two oppositely directed streams. During the movement of lead slag in the furnace drum and the burning of the torch, lead and zinc are more completely extracted from the dust-like material, where the transporting object is compressed air, and the purified flue gas after the gas is further purified by means of a smoke pump is released into the atmosphere.

Аннотация: In the course of continuation of scientific research in the development of Kazakhstani technology for the production of trimanganese tetraoxide pigment, there have been proposed new methods of analysis which make it possible to investigate new nanostructural materials sourced from local deposits. The results obtained are of practical importance and serve as the foundation for developing new technologically advanced domestic production of a competitive product that is in demand both on the national and international markets. The available methods are not able to highlight the particularity and diversity of Kazakhstani manganese ores due to the uneven distribution of manganese minerals and host (waste) rock, the quantitative ratio of rock-forming components and their variation instability. Methods of energy-dispersive analysis of manganese ores from Kazakhstani Zhaksylyk and Bogach deposits have been put forward, electronic micrographs, spectrograms of samples, diagrams of normalized distribution of elements on the surface of samples have been obtained and a comparative analysis with raw analogue samples of some foreign manufacturers has been performed.
