The subject of the extractive metallurgy is related to the study of various processes and combination of processes for the extraction of metallurgical products by raw materials and, as well as, to the selection of the required chemicals. The combination of processes that configure the metallurgical methodology depends on the nature of the reactants and the type of the end metallurgical product. The metallurgical processes are classified into: pyro metallurgical, hydrometallurgical and electrolytic. The aim of the High Temperature Processing course is the teaching of the general principles of the extractive metallurgy the pyrometallurgy. A background on chemistry, physics and physiochemistry is necessary for the course comprehension.
