Summary
The course deepens knowledge in the field of mineral processing using heat in combination with other treatment processes. Heat treatment is one of the basic methods of refining raw materials used in methods of testing fine-grained materials, roasting ores, carbonization of fuels and other
technological processes. Attention is also paid to methods of waste heat treatment.
