Development of a highly efficient technology intended to process hard-to-recover zinc-containing raw materials with preliminary exposure to microwave radiation and ultrasound
Project Manager: Kenzhaliyev B.K.
Relevance:The technology includes pretreatment of raw materials using microwave radiation and ultrasound which makes it possible to influence the structure by weakening the bonds of minerals containing non-ferrous and noble metals with the host rock and enhances their extraction.

Improvement of polymetallic raw materials processing technology with the use of ultramicron inorganic modifier
Project Manager: Turysbekov D.K.
Relevance:The project idea is to improve the flotation technology for processing polymetallic ores using reagents-modifiers of inorganic origin. New ultradispersed colloidal modifier reagents which form an adsorptive film on the surface of separable minerals with a deep fixing character and improve the flotation process, are proposed. The problems that the project is aimed at. The quality of raw materials entering beneficiation is gradually declining, and enterprises are forced to use more hard-to-beneficiate raw materials with low content of useful components and a significant amount of fine sulfide impregnation. At the same time, the process flows and reagent regimes traditionally used do not provide the required beneficiation parameters. The problem of selective separation of minerals with similar technological properties with fine phenocrysts is solved mainly by using directional reagents.
Project goal:Improvement of polymetallic ore beneficiation technology using micron selective inorganic modifier improving the flotation mode of polymetallic raw material processing, increasing zinc extraction by 10-15% and reducing the modifier consumption by 30%.

The results of this stage will be used in the study of the physicochemical and flotation properties of the proposed modifier reagents.
-Study of electrokinetic and flotation characteristics of new ultramicron modifiers of inorganic origin. The fractional composition of the modifier reagents, electrochemical and chemical properties of the new modifier reagents will be studied in different methods of their production depending on the pH of the medium (electrokinetic and redox potentials). Flotation characteristics of zinc and iron minerals will be studied using developed reagent modifiers. New scientific knowledge about the mechanism of action of modifiers will be obtained.

Development of technology and equipment intended to expand the range of refined selenium production on an industrial scale.
Project Manager: Trebukhov S.A.
Relevance: In 2022, the authors of the announced project introduced for the first time in the Republic of Kazakhstan an environmentally safe vacuum distillation technology for refining rough selenium at the Balkhash zinc plant. The technology provides for the production of selenium in the form of ingots with a content of the main component of more than 99.5%. However, during the industrial operation, a limiting stage of the process was determined, which does not allow the technological process to reach the planned production capacity. During the implementation of the project, a constructive solution will be developed to increase the productivity of an industrial vacuum distillation plant and produce granular refined selenium at a production site in Balkhash, without taking into account the manufacture of equipment and the construction of an additional granulation and drying area of the resulting granules. The developed technical solution for the process of grinding ingots and granules of refined selenium using a propeller-type petal mill and a system for sieving crushed material will allow obtaining the material in powdered form with a given size. The use of a technological scheme for obtaining selenium dioxide in the crystalline form will also lead to an expansion of the range of products obtained. The use of crystalline selenium is not limited to pharmacology and the food industry. The resulting material can be used in the scheme of obtaining high-purity selenium. High-purity selenium is used in laser technology and in the electronics industry. The practical significance of the research results: All the developed technical solutions have practical applications and will be used by Kazazmys Progress LLP (a subsidiary of Kazakhmys Corporation LLP) in the production cycle of refined selenium. Obtaining new data will be based on the application of the modern methodology and the use of certified analytical equipment, as well as the use of long-term experience of project performers in creating environmentally friendly technologies and efficient equipment for refining various metals, including selenium. All developments are expected to be carried out as part of the laboratory of vacuum processes of "The Institute of Metallurgy and Ore Beneficiation" JSC, which is one of the leading scientific centers of the Republic of Kazakhstan.
Project goal: The purpose of the claimed project is theoretical research with the subsequent practical use of the results obtained in practice to increase the productivity of the only vacuum distillation equipment in the Republic of Kazakhstan with the expansion of the range of products (granules, powder, crystalline SeO2).
Objectives of the project:
The project will solve three problems, the implementation of which will significantly increase the productivity of the only the Republic of Kazakhstan refined selenium production equipment with the production of commercial products of various grades. Task 1. Determination of the effect of the construction and type of filtering element as well as external factors (temperature, gas flow speed, residual pressure in the system) on the speed of the technical selenium distillation process (passing of steam phase from evaporator to condenser through the steam pipeline with a minimum transfer of non-volatile elements particles, entrained by the mechanical way due to intensive transfer of selenium into steam phase). The received data will allow for improved design of the vacuum-distillation unit and to increase its productivity. Task 2. The conceptual development of the structural design of the refined selenium melt production process from the vacuum distillation unit condenser with obtaining of products in a granular form. The obtained data will allow the creation of the equipment enabling to pelletization of up to 250 kg of selenium melt for 60-90 minutes using the device for drying pellets by a directional air jet. Determination of pellet grinding conditions to obtain powdered selenium of a given size. The obtained data will make it possible to select standard equipment for milling and sieving refined selenium. Task 3. Development of a method of oxidation of elemental selenium with subsequent production of the condensed phase of crystalline selenium dioxide. The data obtained will determine the conditions intended to obtain crystalline selenium dioxide from the vapor phase, eliminating the process of transferring selenium dioxide into solution followed by its crystallization from the solution.
Expected results:
Technical solutions will be proposed as a result of the goals and objectives of the project intended to optimize the only refined selenium production in the Republic of Kazakhstan at the Balkhash Zinc Plant by an increase of equipment productivity and obtaining additional types of high-quality commercial products under GOST 10298-2018 requirements. 3 (three) articles or reviews in peer-reviewed scientific journals indexed in the Science Citation Index Expanded database Web of Science and (or) having CiteScore percentile in Scopus database not less than 35 (thirty-five), and also 1 (one) article in a peer-reviewed foreign or domestic edition, recommended by Committee for Quality Assurance in Science and Higher Education of the Republic of Kazakhstan (CQASHE) will be published.
