The method of recovery of contaminating components from sweepings of the aluminum production for their further return into the electrolyzer is proposed. To concentrate the material, the following processing flowsheet is proposed: milling-classification-reverse flotation-thickening. For the most complete removal of silicon and iron oxides during the flotation of sweepings, the Flotigam 7266 flotation reagent produced by Clariant (Germany), which is a mixture of primary fatty alkyl amines, is used. To remove carbon particles, the combination of pine oil in a mixture with kerosene is used. Flotation is performed using a FML 0.3 flotation machine. The initial material, chamber product, and tails are analyzed for the content of carbon and aluminum, iron, and silicon oxides using X-ray spectral (XSA), X-ray phase (XPA), and chemical analyses. It is established that processing the total material mass does not make it possible to acquire a product with an acceptable content of silicon and iron oxides. Based on the XPA of various fractions of the initial material, it is proposed to process the material fractions containing the minimal amount of contaminating substances (carbon and silicon and iron oxides). Two fractions are selected for processing using the flotation method by the XRS results of various material fractions: -0.071 mm and +5.0 mm. When processing the first of them, the chamber product of the acceptable quality is acquired. A product with a high content of alumina and fluorinated components at low carbon and iron oxide concentrations but a considerable amount of silicon oxide is acquired from a coarse electrolyte-containing fraction (+5.0 mm). The further use of this product is possible to fabricate aluminum-silicon alloys.

Integration of sustainable development in education is now being addressed in numerous educational institutions across the globe. Based on different integration approaches, various teaching methods are being developed, applied and evaluated. A complex relationship exists between curriculum development and sustainable development. The goal of this paper is to present educational practices for integration of sustainable development in engineering education of metallurgy made by Siberian Federal University. We present in this study the results and reflections on the implementation of a specific teaching-learning methodology that has been designed to incorporate sustainability aspects in projects. These 12 ECTS-compulsory subjects are taught following the CDIO standards, according to which the students must develop a somehow innovative product or service from the conception and design to the implementation and operation. The results show that the students perceive that they have developed deep skills in sustainable development, as well as working across disciplines and with different stakeholders.

Engineering education plays a key role in the modern economy, the development trends of which make it possible to develop requirements for the education of future metallurgical engineers and imply a reorientation to project-based training. The project approach in the training of engineers is the basis for educational programs implemented according to the CDIO (Conceive - Design - Implement - Operate) ideology. The key result of the training is the design and implementation competence of future metallurgical engineers, which is formed through design activities aimed at developing the ability to Concieve, Design, implementation, including the management (Implement) and application (Operate) of projects of various levels of complexity. At the same time, the stage of conception includes the initiation and planning of the project, and the stage of application - the completion and distribution of it. The cognitive component of design and implementation competence can be provided by the introduction of the Project Management discipline into the curriculum of bachelors. This paper analyzes the role of this discipline in the development of design and implementation competence in the education of bachelors in the Metallurgy field within the CDIO ideology with an innovative approach to its design. It is shown that the inclusion of the Project Management discipline in the curriculum of the bachelor’s degree in the Metallurgy field and its implementation in the design technology contribute to the development of design and implementation competence of bachelors according to the principles of the CDIO ideology. The implementation of the discipline in project technology meets the requirements of standards 8 (active learning), 7 (integrated learning), 5 (project learning) and allows to develop design and implementation, as well as disciplinary and interpersonal competencies. The results of the work have demonstrated the effectiveness of the project-based teaching technology, in which each participant in the educational process receives benefits that increase his competitiveness.

A solution of the ecological problem of processing waste from metallurgical production is proposed. The results of research on the extraction of sodium and potassium chlorides from foundry slags are shown. A technological scheme based on leaching in hot aqueous solutions with subsequent evaporation is presented.
