Abstract: Present research explores the impact of varying ZnO and ZnF2 concentrations in Nd3+/Tm3+ doped Tungsten-Bismuth-Tellurite glass for fiber optic and solid-state application. Glasses with formula 60.97TeO2–6.7WO3–3.3 Bi2O3–0.03Nd2O3–1TmO–(28-x)ZnO–xZnF2 where x = 0, 7, 14, 21, 28 mol% is prepared using melt-quenching technique. The absorption and photoluminescene of the glass is measured using a UV-Vis-NIR absorption and Photoluminescence spectrometer. About eight absorption bands are evidenced, centred around 467, 525, 581, 687, 726, 793, 870, 1211, and 1691 nm, corresponding to respective REIs (Nd3+ and Tm3+ ions) transitioning from the ground to their excited state. The absorbance of Tm3+ centred around 1691 nm improved with higher ZnF2 contents (28% mol). Physical parameters such as density, molar volume, molar refractivity, and electronic polarizability are calculated. Seven prominent luminescence peaks of Nd3+ and Tm3+ have been identified centred around 509, 586, 611, 626, 648, 795, 800, and 890 nm. Highest luminescence enhancement is evident at 800 nm which corresponds to glass contained ratio of ZnO/ZnF2 at 3:1. These findings highlight the role of ZnF2 in altering the luminescence properties of the glass for fiber optics and solid-state laser applications.

Title: A Comprehensive Study on Polymermodifiedbitumen Blends with PP H030 Mixing Parameters and Homogeneity
Authors: Kosparmakova S.A., Seitenova G.Zh., Nurakhmetova Zh.A., Dyusova R.M., Jexembayeva A.E.
Abstract: The effective inclusion of polypropylene (PPH030) into bitumen during road building is essential for improving the qualities of the material. This research examined the impact of mixing factors on the homogeneity and effectiveness of PP-bitumen blends. The experiment conducted by using granules with a size of 4.3 mm. The mixing process took place at temperatures between 158 and 160°C for a duration of 1.5 hours. Nevertheless, this procedure proved inadequate in achieving enough blending and uniformity, resulting in the existence of unabsorbed particulate matter in the mixing nozzle and vessel walls. Further tests were carried out to enhance the mixing process. The temperature was adjusted to a range of 168-175 °C, and the mixing period was prolonged to 2 hours. Additionally, the PP content was increased to 4 percent. The findings showed a significant improvement in consistency, with no visible undissolved particles. In addition, examination of the mixed samples indicated a rise in the softening point from 53.4 to 61.2 °C when the PP content was increased, accompanied by a loss in penetration and elongation capabilities. The comparison with prior findings demonstrated that the adjusted circumstances resulted in a reasonable degree of mixing, as seen by the constant softening point and decreased penetration and elongation values.

Title: Influence of granule structure mineral fertilizers for their physical and chemical properties
Authors: Smailov B.M., Beisenbayev O.K., Anarbayev A.A., Zakirov B.S., Aravind U.K.
Abstract: In this article, maintaining the quality and commercial properties of mineral fertilizers during repeated transshipment and long-term transportation is one of the important issues. The purpose of the research work is to study the structure of granules of complex mixed fertilizers, as well as to find and develop methods for improving it at the production stage in order to improve the physical and mechanical properties of the finished product. In order to improve the granular structure of the mineral fertilizer, the static strength of the granules, the mass fraction of moisture, the chemical composition and structural shape of the granules were determined using an electron microscope. Using the X-ray microtomography method, experimental data on the internal structure of granules of complex mineral fertilizers were obtained and generalized for the first time, porosity, the nature of the distribution of pores and components of granules by volume were assessed. It has also been studied that the structure of granules and the nature of the pore distribution of fertilizers obtained according to different granulation schemes have fundamental differences, which is explained by the difference in the mechanisms of granule formation. It has been shown that when producing NP and NPS fertilizers using a reverse neutralization scheme, existing defects in the granule structure (cracks and pores) do not impair the physical and mechanical characteristics of the product, which makes it possible to recommend this scheme for use and thereby increase productivity by 20-25% .

Title: Research and development of wood-cement composites as sustainable building materials based on secondary resources
Authors: Ilmaliyev Zh., Zhatkanbayev Ye.Ye., Kurtibay K.A.
Abstract: Conversion of waste into innovative materials that contribute to the sustainable development of infrastructure and the construction industry is an important task in today's society. Wood-cement composites which are building materials that combine wood components and a cement matrix are studied herein. These composites have a number of such advantages as high strength, excellent thermal insulation properties, durability and environmental friendliness. The manufactured composite material is a lightweight concrete based on secondary resources, binders and mineral components. Standardized measuring equipment and methods intended to analyze the chemical composition and physical and chemical properties of wood-cement composites (arbolite) were used in laboratory experimental tests. All samples studied were 40 mm × 40 mm × 160 mm lightweight concrete. Four options to obtain a wood-cement composite in various combinations of binders, minerals and other additives were proposed in the research work. All samples were tested to determine the physical and mechanical characteristics and the optimal composition with improved properties. Secondary resources in the form of wood waste and ash from combined heat and power plants (CHPP) were obtained from industrial structures of the Republic of Kazakhstan. An X-ray diffraction analysis of the CHPP ash was performed to determine the chemical mineral composition that showed a high content of silicon. According to the test results, the CH-4 sample demonstrated high physical and mechanical characteristics. The compression strength of the wood-cement composite sample reached 37.1 MPa, and the bending strength was 7.4 MPa on the 28th day, which proves the high performance properties of this composite.

Title: Hydrothermal treatment of sinters containing thiosalts of non-ferrous metals
Authors: Kvyatkovskiy S.A., Kozhakhmetov S.M., Semenova A.S., Dyussebekova M.A., Shakhalov A.A.
Abstract: Preliminary experiments have shown that the solution to the environmental problem of recycling copper-electrolyte smelting slags is by sulfidization followed by leaching and subsequent separation of selenium, tellurium, arsenic, and antimony from the solution. The first operation of this technology, which provides high selectivity, is sintering. The results obtained indicate the formation of metal thiosalts during sintering in the presence of sodium sulfate and carbonate and a reducing agent at a temperature of 800 0C. An increase in temperature leads to the melting of individual components of the charge and a slowdown in the process of sulfidization of slag components. At lower temperatures, a decrease in the activity of the charge components is observed. The optimal addition of Na2SO4 was 27 % of the slag weight, and Na2CO3 - 8.5 % of the slag weight. Reducing agent consumption is 27 % of the slag weight, sintering time is 2 hours. The optimal parameters for leaching the resulting cakes are temperature 90 0C, L:S ratio = 3:1, leaching duration 2 hours, and sodium sulfide concentration 2 mol/l. The best results for cake melting from cake leaching are temperature 1200 0C, heating rate 10 0C/min, and holding time 30 minutes. Charge composition: cake, 30 % soda ash by weight of cake, 11 % activated carbon. During the smelting, a metallized phase was obtained, consisting mainly of lead (90-91 %), and slag was obtained with a residual content of lead and copper of no more than 0.5 %.

Abstract: The decrease in the quality of mineral raw materials processed by industry, as well as the increase in requirements for environmental protection, necessitate the development of new directions in the technology of their processing. Biogeotechnology refers to one of the modern areas of scientific and technological progress in the field of processing mineral raw materials. Biologically active additives are increasingly used along with the use of microorganisms in the extraction processes for non-ferrous and precious metals, in particular amino acids which are an integral part of the culture liquid of microorganisms. The processes of sulfuric acid leaching of copper from low-grade ore in the presence of amino acids of different structures and their effect on copper electrolysis were studied. Low-grade ore from one of the Kazakhstan deposits was used as the starting raw material. The copper content in the ore is 0.39%. The diffusion nature of the restrictions was established during the study of the kinetics of the process of sulfuric acid leaching of copper, and the rate constants and value of the effective activation energy were calculated, which amounted to 1.817 kJ/mol. The effect of amino acids with different structures on the leaching process was studied. The positive effect was increased in the glycine - leucine - cysteine - histidine - asparagine series. Depending on the structure of the amino acid, the degree of copper extraction into the solution increases in the range of 1-15%. The effect of aminoacetic acid as a biologically active additive on the process of electrolysis of copper from poor solutions was studied. It was established that the process is inhibited by the reduction of monovalent copper to the metallic state in the presence of glycine.

Authors: Dosmukhamedov N.K., Koishina G.M., Zholdasbay E.E., Argyn A.A., Icheva Yu.B.
Abstract: In this work, large-scale laboratory experiments were carried out on high-temperature sintering of clinker with CaCl2. New data were obtained on extracting zinc, lead and related impurities into the targeted products of high-temperature sintering under process scaling conditions. The optimal parameters for high-temperature sintering have been established: t =900 °C, τ = 60 minutes, CaCl2 consumption is 1.3 times higher than its consumption from the stoichiometric required amount (SRA). High-quality zinc sublimates were obtained. The maximum extraction of zinc into sublimates was achieved - 98.2%. New data on changes in the quantitative ratios of clinker ingredients under sintering conditions have been obtained. It has been established that zinc in the form of chloride is concentrated in sublimations. The obtained results form the basis of the final stage of the chlorination technology for processing lead-containing zinc dust from ferrous metallurgy and were used in the developing of a general technology for the selective extraction of zinc and lead into marketable products.

Title: Pyrolysis of synthetic copper telluride in an inert atmosphere
Authors: Nitsenko A.V., Linnik X.A., Volodin V.N., Tuleutay F.Kh., Bakhytuly N.
Abstract: The paper presents the study results of the thermal behavior of synthetic copper telluride in an inert atmosphere at pressures of 92 and 0.07 kPa under isothermal and non-isothermal vacuum-thermal conditions. The thermal analysis results showed that the synthesized copper telluride undergoes polymorphic transformations at 185.7, 259, 318, 350, 470, and 834.5 °C. These transformations were established by early studies and are characteristic of copper tellurides of stoichiometric and non-stoichiometric compositions. It was found that the reduction of the pressure in the system slightly increases the final value of mass loss of the synthetic sample. The X-ray phase analysis results of the residues obtained at constant and increasing temperatures at a pressure of 0.07 kPa showed the absence of the formation of new phases relative to the initial composition. A change in the quantitative ratio of the available phases was found in the direction of an increase in the amount of Cu0.656Te0.344 relative to the initial composition with an increase in the process temperature.

Authors: Kenzhaliyev B.K., Amangeldy B.S., Mukhanbet A., Azatbekuly N., Koizhanova A., Magomedov D.R.
Abstract: Hydrometallurgy plays a critical role in the metallurgical industry by providing an efficient method for extracting metals from ores and secondary materials using aqueous solutions. This approach is particularly advantageous for processing low-grade and complex ores, as well as secondary resources that cannot be effectively processed by traditional pyrometallurgical methods. The objective of this study is to develop specialized software to automate and optimize the calculations necessary for metal extraction in hydrometallurgical processes. The software integrates a complete computational framework for automating the various stages of the hydrometallurgical process, including ore composition initialization, total element mass calculations, and the determination of metal concentrations in both metal products (matte) and by-products (slag). The methodology involves the design and implementation of a web-based application using Django for the user interface and MySQL for robust data storage. The computational module, written in Python, automates the mathematical operations required to simulate complex chemical reactions and metal extraction processes. This module supports real-time processing and ensures accurate calculations for each stage of metal extraction, including leaching, extraction, re-extraction, sorption, and electrolysis. The software also features detailed tables and dynamic graphs that allow users to analyze the distribution of valuable metals and assess the influence of key operational parameters on extraction efficiency. The results show that the developed software successfully manages large datasets, enhances the precision of hydrometallurgical calculations, and minimizes the risk of human error. The implementation of the software leads to significant improvements in the economic efficiency of production by optimizing metal recovery rates and reducing operational costs. Additionally, it supports comprehensive process control by providing actionable insights into each stage of extraction, thus improving the quality of the final metal product. Overall, the software represents a significant technological advancement in the field, offering a scalable solution for industries aiming to streamline hydrometallurgical processes.

Title: Technology of production of aluminosilicate refractories for units processing fluorinated waste
Authors: Sidorina E.A., Isagulov A.Z. Rabatuly M., Yang Y.
Abstract: The aluminium production process through the electrolysis of cryolite-alumina melts involves a series of interconnected, sequential, and parallel technological operations, each defined by a specific level of engineering and technological advancement. The development of the modern aluminum industry is closely tied to the adoption of resource-efficient and environmentally friendly technologies, which focus on recycling secondary materials and industrial waste. Fluorinated carbon-based materials release fluorine into the gas phase at relatively low temperatures when heated, and in thermal units processing fluorinated waste, this fluorine, along with alkali metals, will remain in the gas phase. To enhance the durability of furnace linings against the corrosive atmosphere, refractories with the highest possible density (low porosity) and a high concentration of mullite in the matrix (the finely ground component of the batch) are required. These properties can only be achieved in refractory products produced by the semi-dry pressing method, which ensures high grain packing density and leads to the formation of a ceramic mullite bond after firing.
Keywords: fluorinated carbonaceous materials, crushing, mullite refractories, highly lamellar clay, grinding, mullite-silica products, binding, chamotte, drying, firing.
