This article presents a study on the processing of waste dust from electrical smelting of ilmenite concentrates with the removal of silica from them by alkaline and fluoride methods. The study of the smelting dust leaching by caustic soda solutions included investigation of the effect of sodium hydroxide concentration, process time, temperature, S:L ratio. The optimum conditions of concentrate electric smelting dust leaching - temperature 80-90 °С, duration 90-120 minutes, S:L ratio = 1:5, sodium hydroxide solution concentration 110-115 g/dm3 were determined. The optimum conditions for fluorination of electric melting dust were determined, at which the sublimation degree of silicon fluoride was 84.2 %. Studies have been performed to decomposite obtained silicon-containing sublime in the presence of ammonia agent. The optimum pyrolysis modes that provide the separation of fluoride and silicon oxide - temperature 530-560 °C and duration of 60-80 min have been determined based on the results of thermal analysis and studies on the process duration effect. The silicon oxide content in the obtained product was 96.3%.

Since open-pit mining operations on the elements of development systems have areas with dynamically changing stresses and deformations of the rock mass, the stress-strain state of the array around the sides of the quarry is considered. The objective of the research is to determine the parameters of the stress-strain state of the array that affect the stability of the sides of the quarry. Studies are conducted to determine the parameters of the stress-strain rock mass around the sides of the quarry. A mathematical model has been developed for determining the factors affecting the stability of the sides of the quarry. A multifactorial mathematical model of the stability of the sides of the quarry from mining geological and mining technical factors was obtained, taking into account the creep of the rock mass of the sides of the quarry. According to the formula obtained for the multidimensional model, it is possible to find a set of factors affecting the stability of the sides of the quarry. The obtained dependence makes it possible to determine the desired value from the known values of the factors.
由于开发系统元素上的露天采矿作业具有岩体应力和变形动态变化的区域,因此考虑了采石场两侧阵列的应力-应变状态。研究的目的是确定影响采石场侧面稳定性的阵列应力-应变状态参数。进行了研究,以确定采石场两侧应力-应变岩体的参数。建立了一个数学模型,用于确定影响采石场边坡稳定性的因素。从采矿地质和采矿技术因素出发,考虑到采石场两侧岩体的蠕变,建立了采石场两侧稳定性的多因素数学模型。根据多维模型获得的公式,可以找到一组影响采石场侧面稳定性的因素。所获得的依赖性使得可以根据因子的已知值来确定期望值。

This work discusses the studies based on the microstructural properties of the improved ash and slag materials obtained after flotation enrichment with SEM-EPMA analysis (Scanning Electron Microscope and Electron Probe Microanalysis). According to the results of the analysis aluminosilicate microspheres was found in all four samples with a certain concentration and their similar morphology were identified. The microspheres are characterized by a spherical shape and a rough shell surface. Moreover, the shells are characterized by different morphology, which is typical after flotation enrichment. The size of the microspheres is less than 100 microns. The chemical composition of all four samples are inhomogeneous and was found by linear EDS (Energy-dispersive X-ray spectroscopy) analysis. However, the average values of the content of elements are quite close to each other. The special significance of the work is emphasized by the cross section of the shells of microspheres, which are similar to the crystallization structure of molten metal. They play an important role as materials in the construction industry. According to the results of SEM-EPMA studies, it is recommended to apply ash and slag materials, containing aluminosilicate microspheres, obtained after flotation enrichment, in construction industry.
本文利用SEM-EPMA(扫描电镜和电子探针显微分析)对浮选富集后得到的改良灰渣材料的微观结构特性进行了研究。分析结果表明,四种样品中均存在一定浓度的硅酸铝微球,且形貌相似。微球的特点是球形和粗糙的壳面。此外,矿壳形态不同,这是浮选富集后的典型特征。微球的尺寸小于100微米。四种样品的化学成分均不均匀,并通过线性能谱分析发现。然而,元素含量的平均值彼此非常接近。微球壳的横截面与熔融金属的结晶结构相似,强调了这项工作的特殊意义。它们在建筑行业中扮演着重要的材料角色。根据SEM-EPMA研究结果,建议将浮选富集后获得的含硅酸铝微球灰渣材料应用于建筑行业。

Currently, the production and use of military UAVs in the direction of robotic complexes is actively developing. The purpose and use of military UAVs differ from civilian ones, based on two functions: reconnaissance purpose and a carrier of a warhead. The specifics of military UAVs are their invisibility to enemy radars and ensuring stable transmission of information from the command post. For these purposes, first of all, the UAV material must have the properties of radio transparency. For the production of UAV hulls, power elements, high-strength PCM are needed, which include organoplastics, carbon fiber, fiber glass. The choice of materials for parts of components and assemblies of aviation equipment depends on their operating conditions: operating loads, material properties. Organoplastics (OP) fully meets these requirements among polymer composite materials (PCM). OP have high strength properties along with low dielectric losses (radio transparency) compared to other fiber composites. This paper presents an overview of studies of dielectric and strength properties, as well as ways to improve the mechanical properties of organoplastics. The analysis of the work has shown that for radiotransparent organoplasty, the optimal frequency range of permittivity is 1kHz-12 GHz. The ultimate strength of organoplastics varies in the range from 320 MPa to 1 GPa. The possibilities of increasing the strength of aramid fibers and ways of modifying organoplastics epoxy resins are considered.
目前,军用无人机的生产和使用正朝着机器人复合体的方向积极发展。军用无人机的用途和用途与民用无人机不同,有两个功能:侦察用途和弹头载体。军用无人机的特点是对敌方雷达隐身,并确保指挥所信息的稳定传输。出于这些目的,首先,无人机材料必须具有无线电透明性。生产无人机外壳、动力元件、高强度PCM,包括有机塑料、碳纤维、玻璃纤维。航空设备零部件和组件的材料选择取决于其操作条件:操作载荷、材料特性。有机塑料(OP)完全满足聚合物复合材料(PCM)中的这些要求。与其他纤维复合材料相比,OP具有高强度性能和低介电损耗(无线电透明度)。本文综述了有机塑料的介电性能和强度性能的研究,以及改善有机塑料力学性能的方法。对工作的分析表明,对于辐射透明有机成形术,介电常数的最佳频率范围为1kHz-12GHz。有机塑料的极限强度在320MPa至1GPa的范围内变化。考虑了提高芳纶纤维强度的可能性和改性有机塑料环氧树脂的方法。

Numerous harmful substances of anthropogenic origin that are released into the environment, including petroleum products, are the result of the uncontrolled discharge of industrial wastewater into natural water bodies. Operation of oil refining and petrochemical industry enterprises, gaseous emissions and effluents of industrial enterprises, numerous oil and NP spills as a result of accidents and fires at oil storage facilities and oil refineries lead to pollution of water and soil with considerable amounts of crude oil and products of its processing and create a serious threat to the ecology of regions of Kazakhstan. A cardinal solution to the problem of protection of water bodies from pollution by wastewater polluted by oil and NP is to organize such water management of enterprises, under which the system of recycling water supply is developed as much as possible and the discharge of wastewater into water bodies is minimized. Currently, the sorption method of water purification is the most environmentally safe and expedient. When selecting a sorbent for sorption much attention is paid to its sorption characteristics and the availability of raw materials. In addition, the choice of a sorbent depends on such factors as the quality requirement for purification, the condition of pollutants, the stages of purification and others. A wide range of natural sorption materials used in water treatment and water treatment is known. Natural materials based on modified diatomites and zeolites from Kazakhstan deposits are investigated in this work.
人类排放到环境中的许多有害物质,包括石油产品,都是工业废水不受控制地排放到自然水体中的结果。炼油和石化工业企业的经营、工业企业的气体排放和废水、储油设施和炼油厂因事故和火灾造成的大量石油和NP泄漏,导致大量原油及其加工产品污染了水和土壤,对哈萨克斯坦各地区的生态造成严重威胁。保护水体不受石油和NP污染废水污染的根本解决办法是组织企业进行此类水管理,尽可能发展循环供水系统,最大限度地减少向水体排放废水。目前,吸附法是最环保、最安全、最方便的净水方法。在选择吸附剂进行吸附时,主要考虑吸附剂的吸附特性和原料的可用性。此外,吸附剂的选择取决于净化的质量要求、污染物的状况、净化的阶段等因素。已知在水处理和水处理中广泛使用的天然吸附材料。研究了以哈萨克斯坦硅藻土和沸石改性为基础的天然材料。

Monitoring of displacements and deformations of the earth's surface at the Annensky field 监测安嫩斯基油田地表的位移和变形

In connection with the ongoing depletion of mineral reserves located in relatively favorable conditions, at shallow depths, it is increasingly necessary to involve deposits located in complex mining and geological conditions; occurring at great depths, in complex, poorly studied and potentially dangerous conditions. The deposits developed by the underground method are no exception. Safe and efficient development of mineral deposits by underground method, occurring at great depths, is complicated by the fact that with an increase in the depth of mining, the nature of the course of deformation processes in the rock mass and the degree of their impact on the environment change. Studies of deformation processes, their control and forecast in many cases determine the efficiency and safety of the development of deposits of solid minerals. A practical forecast can be made as a result of continuous tracking in space and time of deformation processes. Currently, to determine the displacements and deformations of the earth's surface of the field, complex monitoring is used, which includes the following methods: - methods of preliminary diagnostics of the rock massif; - repeated high-precision leveling; - satellite geodetic methods, primarily interferometry methods; - other methods of instrumental observations in regional and local areas. It should be noted that ground-based methods used for geomechanical monitoring of earth surface deformations, such as repeated geodetic leveling, as well as the use of satellite geodesy methods, do not fully reflect the temporal detail and spatial scale of the changes in the earth surface deformations. Today, the methods and technologies of space radar interferometry are of particular practical value, which make it possible to obtain areal estimates of vertical and planned displacements of the earth's surface with an accuracy of a few millimeters, regardless of illumination and cloudiness conditions. Space radar interferometry (CRI) is an effective tool for direct mapping of the earth's surface movements and deformations of structures over large areas of the study areas.
由于位于较有利条件下的浅层矿藏不断枯竭,越来越有必要涉及位于复杂采矿和地质条件下的矿藏;发生在极深、复杂、研究不足和潜在危险的条件下。地下法开采的矿床也不例外。由于随着开采深度的增加,岩体变形过程的性质及其对环境的影响程度也会发生变化,因此利用地下方法安全有效地开发深埋矿床的工作变得十分复杂。在许多情况下,变形过程的研究、控制和预测决定了固体矿物矿床开发的效率和安全性。在空间和时间上对变形过程进行连续跟踪,可以进行实际的预报。目前,为了确定野外地表的位移和变形,采用了复杂的监测方法,其中包括以下方法:岩体的初步诊断方法;-重复高精度找平;-卫星大地测量方法,主要是干涉测量方法;-在区域和局部地区的其他仪器观测方法。需要指出的是,用于地表变形地质力学监测的地基方法,如重复大地测量水准,以及卫星大地测量方法的使用,并不能充分反映地表变形变化的时间细节和空间尺度。今天,空间雷达干涉测量的方法和技术具有特别的实用价值,它使我们能够以几毫米的精度获得地球表面的垂直位移和计划位移的面积估计,而不考虑光照和云量的情况。空间雷达干涉测量(CRI)是直接测绘研究区大面积地表运动和构造变形的有效工具。

Currently, to determine the displacements and deformations of the earth's surface of the field, complex monitoring is used, which includes the following methods: - methods of preliminary diagnostics of the rock massif; - repeated high-precision leveling; - satellite geodetic methods, primarily interferometry methods; - other methods of instrumental observations in regional and local areas. It should be noted that ground-based methods used for geomechanical monitoring of earth surface deformations, such as repeated geodetic leveling, as well as the use of satellite geodesy methods, do not fully reflect the temporal detail and spatial scale of the changes in the earth surface deformations. Today, the methods and technologies of space radar interferometry are of particular practical value, which make it possible to obtain areal estimates of vertical and planned displacements of the earth's surface with an accuracy of a few millimeters, regardless of illumination and cloudiness conditions. Space radar interferometry (CRI) is an effective tool for direct mapping of the earth's surface movements and deformations of structures over large areas of the study areas.","PeriodicalId":29905,"journal":{"name":"Kompleksnoe Ispolzovanie Mineralnogo Syra","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69367089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article presents the results of laboratory studies on the effect of the liquid-gas ratio and the foaming agent type on the average water-air micro dispersion size obtained from the foaming agent solution. The size of microbubbles significantly effects the efficiency of flotation and depends on the type and concentration of foaming agent used for their production. A generator was used to obtain water-air micro dispersion. The works were performed to work out the water-air micro dispersion parameters of at different liquid-gas ratio and different performance of the generator. The following foaming agents were used as objects of research: sodium butyl aero flot (BTF), flotanol C-7, butyl triethylenetetramine (B-TETA) at a concentration of 0.5 g/dm3. It has been established, that the optimal phase liquid-gas ratio was 1:1, the optimal capacity of the generator was 6-7.2 dm3/h with an average particle size of air-water micro dispersion- 33-41 mm for BTF solution, 103-107 mm for C-7 solution, 90-93 mm for B-TETA solution. The type of foaming agent used in flotation effects the size and stability of microbubbles. It is established that the flotation agents can be arranged in the following line with respect to their ability to create micro dispersion: IIBK→Senfroth 580→B-TETA→OPSB→Flotanol C-7→T-92→BTF. The best results are shown by BTF that creates micro dispersion of 43-58 μm (t 20-40 °С) and stability of 80 sec with concentration of 0.5 g/dm3.

With the huge explored reserves of potash salts in Kazakhstan, there is still no production of potash fertilizers, the demand for which is constantly growing. In this regard, research of processing of the largest Chelkar deposit ore into potash fertilizers and salts is an urgent problem. The article presents the research results of washed potash ore decomposition with nitric acid and nitric acid suspension filtration. The filtering properties and granulometric composition of the insoluble residue were studied, on what basis the decomposition mode with precipitate double washing was determined. To ensure good suspension filterability, washed, uncalcined ore should be used. Tests of a by-product, gypsum, as a gypsum binder were carried out, which confirmed its compliance with the normally hardening gypsum binder of the G-2 B grade. Advantage of the obtained gypsum is its environmental friendliness. Salts, which are chlorine-free water-soluble potassium-magnesium fertilizers have been obtained by crystallization from nitric acid solution. On the basis of results of experimental-and-laboratory tests, a basic flow scheme has been developed for obtaining potash and complex potassium-nitrogen-magnesium fertilizers from the Chelkar deposit ore.
哈萨克斯坦已探明的钾盐储量巨大,但钾肥仍然没有生产,而钾肥的需求却在不断增长。因此,研究将最大的切尔卡矿床矿石加工成钾肥和盐类是一个迫切需要解决的问题。介绍了硝酸分解和硝酸悬浮液过滤洗钾矿的研究结果。研究了不溶性废渣的过滤性能和颗粒组成,在此基础上确定了沉淀物双重洗涤的分解方式。为保证良好的悬浮滤过性,应使用水洗的、未煅烧的矿石。对副产品石膏作为石膏粘结剂进行了试验,证实了其与g - 2b级正常硬化石膏粘结剂的一致性。所得石膏的优点是环境友好。用硝酸溶液结晶法制备了无氯水溶性钾镁肥盐。根据试验和室内试验的结果,制定了从Chelkar矿床矿石中获得钾肥和复合钾氮镁肥的基本流程方案。

Polygenic stratiform deposits are the largest in the world in terms of barite and manganese reserves, as well as lead and zinc reserves. In the mineral resource complex of the Republic of Kazakhstan, they are of great importance and are distinguished as an independent genetic Atasu type. In the article, the deposits of the Zhailma graben-syncline in a large riftogenic structure are considered as a reference for the Atasu type. The geological structure of the Bestobe stratiform polymetallic deposit located in the eastern part of the Zhailma synclinorium is presented. The stratigraphy of ore formations, mineralization features, morphology of the ore body and the pattern of zoning the distribution of elements in the ore-bearing rocks of the Bestobe deposit are shown. A feature of the deposit is the combination of layered iron-manganese and lead-zinc ores and superimposed zinc-lead-barite mineralization; the sharply subordinate role of hydrothermal-sedimentary ores in the total reserves of lead and zinc; comparative abundance of lead, copper and silver sulfosalts. The analysis of the materials indicates that mineralization at the Bestobe deposit is complex. Its main value is polymetallic ores. The role of iron ore mineralization of the deposit is insignificant. Manganese mineralization is practically absent. Polymetallic ores are conventionally subdivided into lead-zinc-barite, lead-barite, barite and lead-zinc. Strontium is a constant impurity in barites. Lead is mainly concentrated in galena; its insignificant amount is found in geocronite, boulangerite, jamsonite, bournonite, cerussite, anglesite, pyromorphite, plumboyarosite. The bulk of zinc is concentrated in the form of sphalerite.
就重晶石和锰储量以及铅和锌储量而言,多成因层状矿床是世界上最大的。在哈萨克斯坦共和国的矿产资源复合体中,它们非常重要,被认为是一种独立的遗传阿塔苏类型。本文认为,大裂陷构造中的寨马地堑-向斜矿床可作为阿塔苏型矿床的参考。介绍了位于寨马向斜东段的贝贝层状多金属矿床的地质构造。给出了该矿床的成矿地层、成矿特征、矿体形态及含矿岩中元素的分带分布规律。矿床特征为层状铁锰、铅锌矿结合,锌铅重晶石成矿叠加;热液沉积型矿石在铅锌总储量中的急剧从属作用;相对丰富的铅,铜和银硫酸盐。物质分析表明,贝贝矿床成矿作用复杂。其主要价值是多金属矿。铁矿对矿床的成矿作用不显著。锰矿化几乎不存在。多金属矿通常分为铅锌重晶石、铅重晶石、重晶石和铅锌。锶是重晶石中不变的杂质。铅主要富集在方铅矿中;在年轮岩、粉辉石、钾辉石、硼辉石、铜辉石、角辉石、焦闪石、铅辉石中均有少量。大部分锌以闪锌矿的形式富集。
