Ferromanganese - Manganese ferroalloys

Manganese ferroalloys consist of various grades of ferromanganese and silicomanganese used to provide a key ingredient for steelmaking . Most U.s. supply was imported in 2004. The leading foreign source of ferromanganese and silicomanganese, on a gross-weight basis, was south africa, whose exports of manganese ferroalloys to the United states exceeded those of the next four major exporting countries combined (australia, China, Norway, and romania). Manganese ferroalloys were produced domestically mainly at a plant near Marietta, oH, which was owned by France’s eramet Group. some production came from Highlanders alloys llC plant at New Haven, which resumed operations in october after having ceased production in January 2003. In 2004, eramet Group, Ukrainian producer Nikopol Ferroalloys Plant, and BHP Billiton plc of the United Kingdom accounted for a signifcant portion of the world’s production of manganese ferroalloys. In addition to its U.s. plant, eramet Group controlled plants in China, France, Italy, and Norway, while BHP Billiton owned plants in australia and south africa. China continued to be by far the leading producer of manganese ferroalloys with an output greater than that of the next major producers, south africa and Ukraine.
