This article presents the results of study of fluid inclusions in calcite and quartz of the Devonian, Carboniferous and Permian strata of the eastern part of the Precaspian syneclise and the Aktobe Preuralie of Pre-Ural trough. Were determined by microthermometry method the temperatures of melting and homogenization of fluids in crystals of rock and the types of hydrocarbons in inclusions. Interpretation of the measurement results made it possible to determine the most specific values of pressure and temperature, equal, respectively, 350-500 atm and 85°-130°C increasing up to 650 atm / 350°C and more towards the Urals. Accordingly, the geothermal gradient increases from west to east from 24°C/km to 40°C/km in the Aktobe Preuralie. The mineralization of fluid inclusions varies in the same direction from 10-12% to 3-6% of the weight equivalents of NaCl. These results demonstrate three types of gradients: the lowest in the western inner and platform parts of the Precaspian basin (24°C/km), the average in the Pre-Ural trough and the highest in the eastern suture with the Ural folded system. Accordingly, there is an increase in the geothermal background in the Aktobe Preuralie of Pre-Ural trough to 40°C/km.

Uranyl ions sorption of by interpolymer system based on industrial ion exchangers: strongly acidic cation exchanger Amberlite IR120 and strongly basic anion exchanger AB-17-8 was studied. Based on the obtained data, the degree of sorption of uranyl ions by individual sorbents and interpolymer system Amberlite IR120:AB-17-8, polymeric chain binding rate and dynamic exchange capacity of individual sorbents and interpolymer system Amberlite IR120:AB-17-8 were calculated. Based on the data obtained, a comparative analysis of the sorption of uranyl ions by initial sorbents and interpolymer system was carried out, which showed that the highest degree of sorption of uranyl ions by the interpolymer system occurs within the ratios of 50%Amberlite IR120:50%AB17-8. It was found that the maximum degree of sorption of uranyl ions after 56 hours of remote interaction of ion exchangers was 38.0%, when polymeric chain binding rate was 4.63% and dynamic exchange capacity was 0.25 mmol/g. Rate of uranyl ions extraction by the initial ion exchangers 100%Amberlite IR120 and 100%AВ-17-8 was 28.0% and 13.0%. The experimental studies performed have shown a high sorption activity of interpolymer systems for uranyl ions compared to the initial ion exchangers, which makes it possible to use them for highly efficient sorption technology for extracting uranyl ions from industrial solutions.

This article presents the effectiveness of the use of a new complex of aluminosilicomanganese ferroalloys as an oxygen-containing agent necessary in the production of steel and special alloys. The aluminum silicomanganese alloy is smelted using manganese ore and high-ash coal. In addition to the low cost of the melt, it provides deep purification of both aluminum, silicon and manganese, as well as low-carbon steels from non-metallic impurities. Aluminum silicomanganese is intended for investigation of electrical resistivity of charge materials for melting. Questions of research of specific electrical resistance of charge materials for the smelting of aluminosilicomanganese, in particular, high-ash coals, are considered. The measurements were carried out in the Tamman laboratory unit on a special combined experimental setup connected via converters. Studies on changes in the electrical conductivity of coal were carried out in the temperature range 25-1500°C at a heating rate of 15 deg/min. The main regularities of the formation of the electrical resistivity of charge materials depending on the temperature are determined. The proposed method of measurement makes it possible to obtain in-depth information about the physicochemical properties of charge materials. High-ash coal "Saryadyr", having a constant specific electrical resistance at high temperatures, can be achieved optimal melting mode.

In this paper, based on the results obtained, a general assessment of the integrated waste gas treatment technology of the TPP was carried out in terms of its technological and environmental-economic efficiency. The principal possibility of implementing the technology of cleaning waste gases from SO2 and NOx in a continuous mode is shown. When using the developed technology, the sulfur distribution in the gases obtained after purification is ~ 5%, and the main part – 95% is captured by the carbonate melt of alkali metals (Na, K, Li). Extraction of NOx into the melt is ~60%. Thus, already at the stage of chemical absorption of waste gases, favorable prerequisites are created for deep purification of gases from sulfur and toxic nitrogen compounds. An assessment of the economic efficiency of using the developed technology for burning coals with and without a high sulfur content has been carried out. A comparative analysis of the results of the cost of coal without sulfur with the cost of coal with a high sulfur content showed a significant economic effect, formed due to the difference in the cost of coal without sulfur and high sulfur content. Recommendations have been issued in relation to the conditions of small boiler plants operating on coal combustion, which will optimize the organization of the technology and use it in continuous operation.

The article presents the results of studies on the production of ferrosilicon, ferrosilicoaluminium and Fe-Si-Al ligatures when replacing steel chips with magnetite. The object of research was the carbonaceous rock of the Borly deposit. Thermodynamic modeling was carried out using the HSC-5.1, Chemistry software package of the Finnish metallurgical company Outokumpu, based on the principle of minimizing Gibbs energy, and experimental studies-electric melting in an arc furnace at 1000-1400°C begin to form.

It is determined that, from Borly ash under equilibrium conditions, it is possible to obtain ferrosilicon grades FeSi15, FeSi25, FeSi45 and FeSi50 in the temperature range 1260-1860°C and ferrosilicoaluminium grades FS45A10 and FS45A15 in the temperature range 1930-2100°C. It has been experimentally established that ferrosilicon of the FeSi60 brand (68.7% Si, 1.3% Al) is formed from the conclusions of the electric melting of coal waste together with magnetite concentrate, quartzite and coke.

The availability of reliable data on the PVT properties of reservoir fluids plays a leading role in calculating the reserves of oil and gas reservoirs, estimating the oil recovery factor, well testing, numerical reservoir modeling and for making informed decisions in field development design. In practice, the results of field, laboratory and theoretical studies are used simultaneously to substantiate the properties of natural hydrocarbon mixtures. At each of the noted stages, specialists strive to increase the reliability of the data obtained and develop methods for their interpretation. Determining the properties of reservoir fluids of an oil field is a prerequisite for the effective use of various methods of influencing the bottomhole zone of wells, selection of equipment for well operation. The properties of reservoir fluids are determined by various thermobaric conditions and change depending on the current state of the reservoir and the characteristics of reservoir pressure changes. All known methods for determining the properties of formation fluids are divided into two groups: experimental and computational. Each of the groups has both advantages and certain disadvantages.

The article presents an innovative approach to the geometrization of ore bodies during exploration work based on geophysical and/or core studies in wells for the purpose of areal and thickness delineation of hydrogenetic ore mineralization. The method makes it possible to obtain more accurate contours of ore bodies with a minimal increase in the number of wells constructed for this purpose. The method can be used in planning and conducting exploration work on hydrogenetic deposits. On the example of reservoir-infiltration uranium deposits of the Shu-Sarysu uranium ore province located in South Kazakhstan, shortcomings in the geometrization of ore bodies using the traditional method of placing of geological exploration wells are demonstrated, as well as the shortcomings of the proposed in literature methods of ore geometrization and the main advantages of the proposed innovative approach. The developed method solves a number of significant problems in the subsequent planning and implementation of mining and preparatory work at hydrogenetic deposits, contributes to a significant increase in the accuracy of the geometrization of ore bodies and calculation of reserves, and increases the reliability and investment attractiveness of explored hydrogenetic deposits. This method can also be used to save money by reducing the number of wells being constructed, if used for an inverse problem in order to discharge placement of exploration wells in middle part of ores bodies in hydrogenetic fields with a dense drilling grid.

The agglomerate, as a raw material of blast furnace melting, must have such a set of properties that meets the requirements of the blast furnace process to the maximum extent. The quality of agglomerates is assessed by chemical composition, mechanical and physico-chemical properties A high-quality iron ore raw material for blast furnace melting is considered to be an agglomerate with a high iron content with a minimum content of harmful impurities, uniform in size with a minimum content of classes of more than 40 and less than 5 mm, a narrow range of softening and melting temperatures, having high reducibility and high strength. With the condition of the process of reducibility of dissimilar iron ore materials during agglomeration, it is necessary to consider the basic physico-chemical processes and thermodynamic conditions.

Calculations are performed by the Reaction Equation subprogram. During the simulation, zonal technological processes of agglomeration of iron ore components of the charge are taken into account, since each zone corresponds to a certain phase formation due to physico-chemical processes corresponding to their temperature intervals. It is known, as a result implementing all the basic physico-chemical processes of agglomeration of iron ore materials; they should positively affect the quality of the resulting product. As a result, thermodynamic functions were determined in the temperature range of 25-1500°C for chemical reactions occurring in various zones of iron ore materials during the agglomeration process.

The results of studies on the utilization of copper electrorefining solutions, zinc-containing sublimation dusts of pyrometallurgical processing of non-ferrous metal scrap are presented. Zinc-containing sublimation dusts for the regeneration of commercial electrolyte by the neutralization method were used for the first time. Contained in dust, zinc oxide, when dissolved in a sulfuric acid electrolyte, binds sulfate ions of free sulfuric acid and increases the pH of the solution. When the pH of the precipitation of non-ferrous metals is reached, they are precipitated in the form of hydroxides, which makes it possible to return to processing a significant amount of copper, nickel, zinc, lead and tin contained in them. Studies of the material composition of the commercial electrolyte of copper and zinc sublimates for the processing of non-ferrous metal scrap have been carried out. The conditions for purification of the electrolyte by the method of staged neutralization are determined. The first stage of neutralization was carried out with zinc sublimates, the second and third stages with potash. As a result of the first stage of neutralization to pH 4.7, lead was obtained - a tin-containing product that can be processed together with lead-containing copper electrorefining sludge. As a result of the second stage of neutralization with potash to pH 7.1, a precipitate was obtained, after treatment of which in a KOH solution, a precipitate of copper oxide was obtained. As a result of the third stage of neutralization to pH 9.5, a nickel-zinc-containing precipitate was obtained. After treating the precipitate with a KOH solution, a zinc-containing solution and a nickel-containing precipitate were obtained, after calcining which a nickel oxide precipitate was obtained.
