Аннотация: The article discusses the influence of the temperature factor on the value of hydrostatic pressure while drilling of geothermal wells using chemical reagents based on water - soluble polymers in the process of drilling deep wells, which ensure the stability of drilling fluids at high temperatures. As mentioned earlier, the regulation of hydrostatic pressure by increasing the drilling mud densityat high temperatures is inappropriate . Therefore, it is necessary to take measures to improve the sedimentation stability of drilling muds.

Аннотация: In this work, the kinetics of electrochemical oxidation-reduction of thallium in aqueous solutions of sulfuric acid is studied by potentiometry. To characterize the mechanism of thallium electrooxidation, the following parameters were calculated: the order of the reaction and the effective activation energy of the process. The impact of electrolysis modes: current density, concentration and temperature of the electrolyte on the dimensional charac-teristics of the obtained thallium (I) sulfate was investigated.

Modified sorbents and their application for extraction of metal ions. [Текст] / N. C. Murzakassymova, N. A. Bektenov, M. A. Gavrilenko // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 75-79

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.

Аннотация: The qualitative and quantitative compositions of the valuable biologically active substances, species and strains of microalgae are related the genus of CyanobacteriaSp.platensis and Sp.labgrinthifosmis that were isolated from local nature and grown in semi-production facilities were considered. In order to adapt for mass cultivation, algae were first grown in greenhouse conditions. The algae were cultivated within 12 days. The produc-tivity in the tubular cultivator with stirring of Sp.platensis was 3.8 g / l, protein (73.0%), and Sp.laberinthiformis was 2.6 g / l of protein (63.1%). Similar studies were carried out in the open-air conditions that showed an increase in the amount of illumination causes a significant restructuring of the entire photosynthetic apparatus of algae. The accumulation of Sp.labyrinthiformis 2.7 g / l a.d.c., protein 62.21%, and Sp.platensis 4.08 g / l, protein 75.3%, were within 10 days. The content of protein and carotenes sharply increases in comparison with the greenhouse conditions. It was found that the addition of Sp.platensis suspension, as a protein-vitamin supplement for the bulls’ feedstuff, stimulates physiological processes that improves the biochemical parameters of their blood, the digestibility coefficient of nutrients by 8-9%, positive mineral balance, increases live weight gain (17.4%) and slaughter yield of the bulls (3.6%). So, the suspension of Sp.platensis is recommended for use as a protein-vitamin supplement in livestock farms that will allow having a significant economic effect in livestock farming, in average 20-25% profits per yearly.

Аннотация: The object of research is technogenic mineral formations-tailings of the Bestube processing plant located within the Bestube gold field. Analytical and technological studies of stale tailings have been carried out. According to the results of analytical studies, the material composition of stale tails was established. The average gold content in stale tailings according to assay analyses is 0.565 g/t, silver 1.56 g/t. The tailings belong to the category of poor sulfide, oxidized raw materials. The main industrially valuable component in the tailings is gold, silver has a subordinate value, and other metals are not of industrial value. Mineralogical analysis established that stale tails are represented by quartz, muscovite, clinochlore, albite, dolomite. Studies were conducted on agitation leaching of stale tailings of the initial size (64.08% of the class –0.074 mm) and after additional grinding to the size of 90% of the class –0.074 mm. Reducing the size contributes to the dissolution of gold from the tailings: at the initial size, 66.28% of gold is dissolved, after regrinding the degree of dissolution of gold from the tailings increases to 87.23%. The results of research on agitation leaching of gold have shown a high efficiency of hydrometallurgical technology for processing stale tailings of a processing plant.

Аннотация: In the dairy industry, in recent years, baromembrane technologies (microfiltration, ultrafiltration, nanofiltration, reverse osmosis) have become increasingly widespread, which make it possible to obtain milk raw materials that are safe from a microbiological point of view and to standardize the protein mass fraction, concentration and fractionation of milk constituents. These filtration methods are definitely an alternative to traditional manufacturing processes. They are integrated into many production steps for a wide range of whole milk products, cottage cheese, cheese, etc.

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.
