Research of kinetics of zinc leaching with sulfuric acid from smithsonite

The study investigates the kinetics of zinc leaching from smithsonite with sulfuric acid in order to expand the zinc production feedstocks. The recovery rate of zinc from smithsonite into water-soluble zinc sulfate was found at different leaching time and temperature. Sulfuric acid concentration, its consumption and smithsonite particles size selected in this work for leaching of zinc from this mineral using the indicated solution allowed to determine the magnitude of “apparent” activation energy of the smithsonite reaction with the indicated acid, equal to 2,633 kJ / mol. The calculated value of E, shows that the process investigated is accompanied by diffusion phenomena

Analysis of copper-containing products for the content of noble metals

In the article we are presenting the results of electron microscopy study of the samples of blister copper taken from copper production. It was shown significant amount of noble metals - silver and gold. As a result, silver was found in the range of 0.29-0.59%, gold - up to 0.66%. The methodof assay-gravimetric detection of gold and silver in samples of blister copper is described

Consideration of the Basic Competencies of a Preschool Teacher in Curriculum Modernization

The work deals with an important aspect of teacher training — the formation of competence in the field of technologization of the pedagogical process. An updated theoretical model of a holistic pedagogical process is presented, which is the basis for coverage of the criteria for the formation of abilities for the constructive and systematic introduction of technologies into pre-school education. The author’s questionnaire The Scale of Self-Assessment of Pedagogical Abilities for the Technologization of the Pedagogical Process was presented. The article provides the results of its testing on a sample of a total of 412 respondents, including 170 preschool teachers with work experience from 1 to 25 years, 200 — students-future teachers, 42 - PEF coordinators. Based on the comparison of samples of teachers with different work experience, it describes how the nature of professional activity determines the specific structure of competences in the field of TPP. The experiment was a part of research; authors showed the conditions for the implementation of a special curriculum, which helps effectively prepare teachers for the use of modern educational technologies

Web Technologies in the Development of Computational Thinking of Students with Mental Disabilities

Computational thinking is an important and necessary part of a modern person’s thinking. It has been proven that the development of this way of thinking in students with mental disabilities allows them to navigate quickly in the modern world, identify problems and create complex solutions. Online schooling during the COVID-19 pandemic demonstrated the possibilities of the usage of web technologies in the education of children with mental disabilities. This study aims to evaluate the impact of web technologies on the development of computational thinking of students with mental disorders. The experiment involved 14 students aged 8-12 and 4 tutors. For 8 weeks children were trained in computational thinking and computer science. Assessment of computational thinking was performed with cCT-test by El-Hamamsi et al. before and after the experiment. After conducting computer science lessons using web technologies the respondents showed a higher level of computational thinking (M=15,7, SD=3,69), compared to the results of preliminary testing (M=5,93, SD=2,3). Web technologies can significantly increase the effectiveness of inclusive pedagogy, which establishes the importance of integrating web technologies into the teaching system in inclusive classes of general education schools
