Based on these studies, it is possible to predict the future state of silicomanganese.The global silicomanganese mar-ket is expected to grow from $25.98 billion in 2022 to $28.33 billion in 2023 at a cumulative annual growth rate (CAGR) of 9%. The Russian-Ukrainian war has undermined the chances of a global economic recovery after the Covid-19 pandemic, at least in the short term. The war between the two countries led to economic sanctions against many countries, rising commodity prices and supply chain disruptions, which caused inflation of goods and services and affected many markets around the world.The global silicomanganese market is expected to reach $38.35 billion in 2027 with an average annual growth rate of 7.9%.It is expected that the growing demand for steel products will contribute to the further growth of the silicomanganese market. Steel products are products that are made from iron and metal in factories by various methods and mixed with alloys such as carbon, zinc and others. Silicomanganese is used to produce various types of steel for various purposes, such as carbon steel, alloy steel, manganese steel. Such use leads to an increase in demand for silicomanganese in theproduction of steel products. For example, in 2022, according to the World Steel Association (WSA), the Belgian international trade organization for Fer-rous Metallurgy, steel consumption will increase by 0.4% in 2022, reaching 1.840 million tons. Steel consumption will in-crease by 2.2% in 2023, reaching 1.881 million tons. Thus, the growing demand for steel products stimulates the silicomanga-nese market.

In modern materials science, much attention is paid to the production of new types of ceramics that have in-creased resistance to external influences, as well as high strength parameters. At the same time, among the ceramics one can single out aluminum-magnesium spinel, which has a unique combination of properties that open up opportunities for its use as structural materials in the nuclear industry and aircraft construction, as well as metallurgy in the manufacture of cruciblesfor smelting metals. It should also be noted that recently special attention has been paid to research aimed at improving the proper-ties of these ceramics by doping or alloying them, which makes it possible to change their properties and increase resistance to external influences. The purpose of this study is to study the effectiveness of scandium doping of aluminum-magnesium spinel (MgAl2O4) obtained using the method of mechanochemical solid-phase synthesis, on changing the dynamics of phase trans-formation processes. The choice of ceramics based on MgAl2O4spinel as objects of study is due to the great prospects for its use in structural materials science, due to the unique physicochemical and strength properties, and the addition of scandium to the composition of this ceramic makes it possible to increase resistance to external influences and increase crack resistance.Using the method of X-ray phase analysis, it was found that an increase in the annealing temperature of alumina-magnesium ceramics doped with scandium leads to an enrichment of the composition with the γ-phase of aluminum oxide, with the for-mation of a substitutional solid solution of the MgAl2O4/Al2O3type, and also to a decrease in the concentration of the ScAlMgO4phase.At an annealing temperature of 1500°C, inclusions are formed in the composition of ceramics in the form of an MgAl intermetallic phase with a high degree of structural ordering of the crystal lattice (the deformation distortion factor is –0.35 (compression strain)).

Today, Kazakhstan, like many other countries, is actively seeking ways to adapt to global climate change, seek-ing to ensure sustainable economic development, social responsibility and environmental protection in the context of interna-tional cooperation. In early 2023, the «Strategy for Achieving Carbon Neutrality of the Republic of Kazakhstan until 2060»was adopted, which was the result of significant work on the implementation of the «Concept of Transition of the Republic of Kazakhstan to a Green Economy», as well as the development and implementation of state programs of industrial-innovative development and implementation of the UN Sustainable Development Goals. The main goal of the Strategy is to achieve sus-tainable development of Kazakhstan's economy to climate change and carbon neutrality by 2060. There will be a gradual planned reduction in the share of coal-fired generation with an increase in the share of RES and alternative energy, as well as the use of natural gas as an intermediate fuel. In the medium and long term, there is uncertainty about the availability of suffi-cient water resources, so a long-term vision for the development of hydropower in Kazakhstan will be formed. In this regard, there is a need to develop the production of alternative energy in our country. Among non-conventional energy sources, geo-thermal energy -heat generated naturally in the Earth's interior -occupies the second place, second only to solar radiation. In recent years, unique factual material on thermal waters of Cretaceous deposits has been obtained in the territory of Zharkent depression. Zharkent depression possesses a huge potential of natural thermo-mineral resources, which have not found rational economic application so far. Development of thermal waters is actual in conditions of development of production of alternative kinds of energy and at transition of the republic on rails of «green economy».

The study is devoted to the analysis of metasomatic zoning and features of mineralization of porphyry copper deposits ofthe North-Eastern Balkhash region, comparing them with other analogs around the world. Based on geological, mineralogical, and hydrothermal changes, the key characteristics of the Aktogay, Aidarly and Kyzylkiya fields were identified. Methods included rock and mineral analysis, geochemical studies, and comparative analysis with global deposits. The results showed the uniqueness of Kazakhstan deposits in terms of mineral composition and zoning structure. The conclusion empha-sizes the importance of these deposits for understanding the formation of porphyry copper systems and the potential for further research in this direction. The copper ore deposit of North-Eastern Balkhash region is located 450 km northeast of Almaty, within the Balkhash-Ili suite of the Central Asian Orogenic Belt, an orogenic structure over 800 million years old.The porphyry formations are found within the Koldar plutonic massif, which dates from the Late Devonian to the Early Carbonif-erous period. Laccolith intrusions of diorite-granodiorites extend 17 km in an east-west direction here.The Koldar plutonic massif includes plates of volcanogenic sedimentary rocks consisting of Carboniferous andesites and dacite-rhyolites. The Ak-togay deposit occupies the central plate, composed of volcanic rocks and bounded by magmatic formations. The stocks of porphyritic granodiorites that intrude into the volcanic layers date from the Middle Carboniferous period.

The article is devoted to reviewing the issues related to the application of geophysical methods for solving the problems of monitoring the development of solid mineral deposits. The problems considered in the work are highly relevant in connection with the recent increase in the frequency of natural and man-made disasters caused by the disturbance of the rock mass during the construction of mine workings and the exploitation of ore deposits developed by underground methods.This is especially pertinent for deposits at a late stage of development. Based on an analysis of foreign and domestic scientific litera-ture, the authors provide a detailed examination of the possibilities of using various modifications of geophysical methods in the mining industry at the stages of deposit development and operation.Particular attention is paid to the efficiency of seismic exploration methods in monitoring the development of ore deposits mined by underground methods at great depths. It is shown that the use of geophysical methods is one of the most effective ways to account for the behavior of natural and technical sys-tems in underground workings, depending on the current state of the geological environment and artificial impacts on rock massifs.A well-founded conclusion is made that systematic monitoring and prevention of the technogenic state of underground workings, as well as the study of the current state of the rock mass and ore deposits in hard-to-reach areas using modern geo-physical technologies, form the basis for the effective and safe development of long-exploited solid mineral deposits.The presented review is used for the scientific and practical substantiation of research work carried out by a team of specialists from KazNITU named after K.I. Satpayev, focused on developing a technology for assessing the geomechanical state of mined-out spaces using seismic methods during underground mining of minerals in the complex mining and geological condi-tions of copper sandstone deposits in Kazakhstan.

The clarification of industrial wastewater from gravity and flotation processes depends on both the type and concentration of the applied flocculants.A systematic review of dewatering methods for sludge from treatment facilities processing fine-dispersed chrome ores was carried out with an analysis of the advantages and disadvantages of the selected methods.Overall, the results highlight the importance of using flocculant rea-gents and applying innovative methods for the sedimentation of fine-dispersed chrome ores to enhance beneficiation efficiency and improve resource utilization.

The paper presents the results of comprehensive studies of the processing of ferrous metallurgy dust by high-temperature sintering together with CaCl2. Using modern research methods of X-ray fluorescence spectroscopy, inductively coupled plasma mass spectroscopy ICP-MS (Agilent 7700s ICP-MS System Technologies), powderX-ray diffraction (Ultima III (Rigaku Corporation, USA), the composition of dust and the forms of metals in them have been studied: zinc in dust is mainly represented in in the form of zincite (ZnO) and in the form of franklinite (ZnFe2O4). Zinc chloride hydrates (Zn5Cl2·(OH)8·H2O) were found in a small amount. Lead was found in a metallic form.The results of the influence of temper-ature and consumption of CaCl2on the distribution of Zn, Pb between sintering products (clinker, sublimates) are presented. The optimal process parameters were established: t=900ºC, τ=60 minutes, the consumption of CaCl2is 1.3 times higher than its consumption from the SRQ. High quality zinc sublimates were obtained, % by weight: 40.87 Zn; 0.16 Pb; 44.82 Cl; 13.04 O; others. A high recovery of zinc in distillates has been achieved –98.9%. The presence of a minimum lead content in the distillates will not significantly affect their quality. New data on the extraction and distribution of zinc and lead betweenthe products of high-temperature sintering of clinker together with CaCl2have been obtained. It was found that at temperatures above 700ºC, the zinc content in the clinker decreases sharply. The minimum zinc content in the clinker of 0.62% corresponds to a temperature of 900ºC. An increase in temperature to 1000ºC only slightly reduces the zinc content in the clinker to 0.6%.

The geological structure of low-viscosity oil reservoirs, represented by carbonate collectors in the Ferghana re-gion of Uzbekistan, is characterized by a wide range of variations in geological and physical factors as well as in the parame-ters of implemented development systems. Based on the refinement of parameterscharacterizing reservoir structure, geological heterogeneity, and the reservoir properties of productive layers, as well as the results of developing fields in the late stage of exploitation, a geological-statistical model has been developed using the method of multifactorial correlation and regression analysis. This model allows for the qualitative and quantitative assessment of the influence of geological and technological factors on the oil recovery factor for carbonate reservoirs in the Ferghana region.The study demonstrates the dominant influ-ence of geological factors on the oil recovery factor, while among technological factors, only the well spacing density showssignificant impact. The developed geological-statistical model for the oil recovery factor is recommended for use in justifying geological and technical measures to optimize the development systems of these fields.

The article deals with the results of dynamic interpretation of 3D CDPM seismic data in combination with log-ging data. The authors were faced with the task of comparing the results of pre-stack seismic inversion and neural learning technology in the conditions of the Arykty gas condensate field. The reason for this was the low seismic knowledge of the studied area, the fairly good predicted prospects for oil and gas content in the region, and the need to study the criteria for selecting a particular dynamic interpretation procedure. In this regard, an attempt was made to consider the structure and oil and gas content of the Arykty gas condensate field from the point of view of a comparative analysis between pre-stack inver-sion, which is currently actively used in the geological exploration industry within the framework of a standard interpretation graph, and neural machine learning. Justification for the relevance of the studies performed is availability of new wells andupdated logging data, the ability to update and to compare the results of synchronous pre-stack inversion, and the ability to test neural learning algorithms. The conducted studies make it possible to identify criteria for the preferential use of machine learn-ing in the conditions of the Arykty field, to take a fresh look at the features of the internal structure of the rocks that make up the productive part of the section, and to demonstrate physically the advantages of machine learning results in comparison with pre-stack seismic inversion.
