Metallurgical Engineering is a broad field that deals with all sorts of metal-related areas. The three main branches of this major are physical metallurgy, extractive metallurgy, and mineral processing.
Physical metallurgy deals with problem solving: you'll develop the sorts of metallic alloys needed for different types of manufacturing and construction. Extractive metallurgy involves extracting metal from ore. Mineral processing involves gathering mineral products from the earth's crust.
