Metallurgy involves extracting metals or metal compounds from minerals and processing them into materials with specific properties through various techniques. With a long history, metallurgical technologies have evolved from early bronze smelting to large-scale modern steel and non-ferrous metal production, encompassing pyrometallurgy, hydrometallurgy, and electrometallurgy. The application of physical chemistry has transformed metallurgy from empirical practice into a systematic science, giving rise to academic fields such as metallurgical engineering.
The metallurgical industry can be divided into ferrous metallurgy and non-ferrous metallurgy. Ferrous metallurgy mainly includes the production of pig iron, steel, and iron alloys, while non-ferrous metallurgy covers all other metals. Additionally, it encompasses rare metal and powder metallurgy. Metallurgical products are widely used in machinery, energy, chemical processing, transportation, construction, aerospace, and defense industries.
