methods, principles, process, technologies and equipment of metal extraction with the aim of increasing production efficiency, saving energy, reducing pollution, improving product quality, lowering costs and expanding product variety.As one of the oldest disciplines, the Department of Metallurgical Engineering plays a central and major role in research and teaching at Kunming University of Science and Technology. It started to recruit postgraduate students in 1964, offer master’s program in 1980 and . program in 1984, and establish the postdoctoral station in 2001. The Department has 1 national key discipline for nonferrous metallurgy, 2 provincial key disciplines for nonferrous metallurgy and physical chemistry of metallurgy, 1 national engineering laboratory for vacuum metallurgy, and 1 provincial key laboratory for vacuum metallurgy of nonferrous metals.
