The main molybdenum ore is molybdenite (molybdenum disulfide). It is processed by roasting to form molybdenum oxide, and then reducing to the metal. The main mining areas are in the USA, China, Chile and Peru. Some molybdenum is obtained as a byproduct of tungsten and copper production. World production is around 200,000 tonnes per year.
