The Metallurgical Industry is the industry concerned with the extraction, refining, alloying and fabrication of metals. The word “metallurgy” was originally an alchemist's term for the extraction of metals from minerals, and the word’s ending “-urgy” signifies it is a manufacturing process. Historical developments in ferrous metallurgy can be found in a wide variety of past cultures and civilizations, among which being the ancient and medieval kingdoms of China. Many applications, practices, and devices associated or involved in metallurgy were established in ancient China, such as the innovation of the blast furnace, cast iron, hydraulic-powered trip hammers, and double acting piston bellows. The metallurgical industry is one of the oldest industries in Binzhou, with technology and processes such as extractive metallurgy being fully developed. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the
extracted raw metals into a purer form. In order to convert a metal oxide or sulfide to a purer metal, the ore must be reduced physically, chemically, or electrolytically.
Shandong Weiqiao Poineering Group Co., Ltd and ZhouPing Iron and Steel Group are the two biggest metallurgical corporations in Binzhou. Weiqiao Poineering is the leader of extraction, refining and engineering of aluminum, with technology and methodology that define industry standards in China. The ZhouPing Iron and Steel Group focuses on steel production and it has produced up to 16.7 million tons of steel per year. The company specializes in making world-class grade stainless steel, alloy steels and other types of specialty steel, contributing to a significant portion of total steel production in China.
