OLEKSANDR BEREZNIAK

Mining engineer-process engineer, candidate of technical sciences, associate professor.

Graduated from the Dnipropetrovsk Mining Institute in 1981, majoring in "Mineral processing" with the qualification of mining engineer-process engineer.

Candidate of technical sciences, specialty 05.15.08 – Mineral processing, since 2002; dissertation topic: "Thickening of suspensions using compression acoustic waves"

Associate Professor of the Department of mineral processing from 2011 to 2022.

In 2016-2018 took part in work with foreign students of the International University of Resources, namely, taught a course of lectures and laboratory works in English "Theoretical foundations of materials processing".

Completed advanced training in the form of Internship at the Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine (ITM of NASU and DCAU) from September 21, 2020 to November 1, 2020 in the amount of 180 hours / 6 ECTS. The acquired knowledge and skills were implemented in the educational process of the department of technological engineering of materials processing of the Dnipro University of Technology.

Received advanced training in the form of the Professional Development Online Training Course "DIGITAL RESEARCH", organized according to the international staff mobility framework as part of non-formal education and aimed to improve professional/soft skills in the field of digital research, supported by the German Academic Exchange Service (November 20^th, 2023 – March 15^th, 2024) in the amount of 120 hours / 4 ECTS.

The range of scientific research includes: the process of dewatering finely dispersed sediments and the possibility of its intensification, in particular, without reagents; the process of separating weakly magnetic materials by high-gradient magnetic separation; the process of demagnetization of ferromagnetic materials in order to improve the quality of their processing; the process of flotation of minerals using a highly aerated suspension.

From 2021, takes an active part in the work of the Center for processing and beneficiation of mineral and man-made raw materials of the Dnipro University of Technology.

As part of the reorganization of the educational process in the specialty 184 Mining, from September 2022 was transferred to the position of associate professor of the department of ecology and environmental protection technologies.

Teaches disciplines: "Scientific foundations of rational nature management"; "Conducting scientific activities"; "Processing of man-made raw materials"; "Mineral processing"; "Sustainable Development Strategy"; "Theoretical foundations of materials processing"
