The paper presents the results of studies on the sorption leaching of gold-containing ore of the Vasilkovskoye deposit. Kinetic dependences of the sorption of gold and associated metals from cyanide-alkali solutions under different physical and chemical factors were obtained. It was found that gold on the AM-2B resin sorbed at a higher rate than, for example, copper and zinc. The solutions were analyzed using modern devices of a new generation: FT-IR spectrometer "Avatar 370". Laboratory studies were performed to determine the gold sorption rate by the AM-2B anionite from cyanide-alkaline solutions. It was found in the process of sorption of gold from multicomponent cyanide-alkali solutions on AM-2B anionite of mixed basicity, with the macroporous structure containing benzyl dimethylamine and dibenzyl dimethyl ammonium functional groups, that an important factor of qualitative and quantitative separation of gold and impurity metals is the concentration of cyanide and hydroxyl ions in solution. The temperature effect on the sorption rate of gold from cyanide-alkali solutions was studied with the temperature dependences F of t, Bt, of t, ln (l - F) of t, and D of t that show that the sorption process of dicyanoaurate ions is controlled by mixed diffusion.

“…Institutional research laboratories are required, where students can perform or observe experiments while providing technical science information. In Kazakhstan's Institute of Metallurgy and Ore Beneficiation, there are numerous laboratories where future engineers can perform experiments with their qualified supervisors; they also have access to plants and factories (Kenzhaliev et al, 2019;Koizhanova et al, 2020). TVET institutions should also be able to provide the institutions with the latest technology machinery to cater to new information and skills between instructors and students.…”

Developing in the field of technical and vocational education and training (TVET) continuously is a challenge for the career of TVET instructors to maintain their success. It is very necessary to encourage teachers for making progress in teaching and efficient learning. It is also of great importance to have the ability to understand the skills that are required by their job needs. From a broader perspective, those trained through the processes of vocational learning will meet the labor market's skill needs. In the aftermath of this study, teaching should be focused on the profile of the teaching competencies of the TVET-instructor. The Delphi approach was the compilation, interpretation, and evaluation of qualitative data in this study. Qualitative data was collected from the 11 expert panels of TVET, based on their skills and experience. The quantitative data were collected using the questionnaire set by the researcher based on the competence of the teaching elements proposed by the Delphi system. The random sampling technique was used as respondents from five selected public skills training institutions in the selection of 106 mechanical engineering and manufacturing technology instructors. Research findings have shown that the dimension of teaching technique is important for teaching profiles of competencies at the instructors of the Public Skills Training Institution TVET. In the context of mastering the competence for the implementation of the 4th Industrial Revolution, the study also found that the use of project-based learning methods is ranked as the lesser in teaching methodology as it should be reinforced at five selected training institutions for public skills.

“…The states of acceptance and love, empathy and reflection, as well as congruence, authenticity largely arise "automatically": a person comprehends the essence of love and the fact that love is not constant comfort, on the contrary, it implies more or less significant tests, and "Gifts of fate" [18], she is not the end, but all being, she is not permissiveness, but freedom and responsibility, she is the integrity of life, not the division into good and bad, etc. A person and an organization also comprehends that it is easier not to wait for help, but to render it yourself: to the same or even more needy people and groups [11,12,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The purpose of a business is not the maximum profit for the sake of profit, power, etc., but the service of societies, a joint, if possible harmonious, development.…”

The article is devoted to the analysis of the main principles of business and professional consulting as a practice of interpersonal relations and the being of its subjects. The main problems of clients connected with violations of their intrapersonal and interpersonal relations, as well as relations to their own life (being) in general, subjects of business consulting as participants in business processes and life, in general, are considered. The purpose of the study is to analyze the basic principles or meta-technologies of business and professional consulting in educational organizations. The article summarizes the basic concepts and concepts of business and professional consulting, reflecting its meaning as helping the socio-psychological practice of developing people and educational organizations. Relying on the tetrad of principles of psychological counselling, isolated in the school of C.R. Rogers, as well as the leading principles of organizational counselling in educational organizations, the authors consider their manifestations and features in the main aspects and dimensions of advisory interaction. Traditionally, such dimensions are distinguished: power/management system, competence/experience system, love/system of relations. Each of these dimensions is associated with one or another intention of consultative relations in educational organizations: transformational, dialogical, and relational. Within each of these intentions, the basic principles of business and professional consulting in educational organizations are manifested as meta-technologies or meta-technology groups. In addition, the authors consider the principles of business and professional consulting in educational organizations in relation to the life of the consultant and the client as a whole, as "meta-technologies of life".
