Summary

The course focuses on the theoretical foundations of the processes applied at production of non-ferrous metals. Production of non-ferrous metals uses a wide range of raw materials of diverse chemical nature. This is related to the diversity of their processing procedures. Students will learn the bases of pyro-metallurgical, hydro-metallurgical and electro-metallurgical processes, as well as selected processes of production of heavy, light, noble, high-melting, radioactive and rare earth metals. They will also be acquainted with the preparation and technical application of alloys of non-ferrous metals.
