Subject aims expressed by acquired skills and competences
A graduate of the Mineral and Waste Processing III course will acquire comprehensive knowledge of technological processes in mineral processing and waste recycling, including gravity, magnetic, electrostatic, and physico-chemical separation methods. The student will master the principles and practical applications of flotation as a key method of separation based on differences in surface properties of particles, with a thorough understanding of its chemical, physical, and thermodynamic foundations. They will be capable of independently assessing material floatability, designing and optimizing mineral processing and recycling technologies, including the selection of appropriate equipment and chemical reagents. The student will gain competencies in planning laboratory tests and interpreting their outcomes to support the efficient utilization of both primary and secondary raw materials, aligned with national raw material policy objectives and the principles of sustainable development. They will be prepared to analyze, design, and manage processing technologies in the field of mineral beneficiation and recycling, with a focus on material efficiency and environmental responsibility.
