In , China’s use of molybdenum reached a record level of over 97 000 t whilst it produced almost 92 000 t of molybdenum.Accordingly, the country was a netimporter of molybdenum. The majority (nearly 85%) of molybdenum production in China originates from primary mines, where molybdenum is the sole mineral target, while the
Molybdenum is a silvery white, soft metal with the sixth highest melting point (2623 °C) of any element, exceeded only by tantalum (2996 °C), osmium (3045 °C), rhenium (3180 °C), tungsten (3422 °C) and carbon (3550 °C). Molybdenum’s basic properties are compiled in Table 1 [ 1 ]. Table 1 Basic properties of molybdenum and its
U.S. mine production of molybdenum in increased by 13% to 49,000 tons compared with the previous year. Molybdenum ore was produced as a primary product at two mines—both in Colorado—whereas seven copper mines (four in Arizona and one each in Montana, Nevada, and Utah) recovered
The Chevron Questa mine is a molybdenum mine located in Taos County, New Mexico in the southwestern United States. It is one of the superfund sites designated by the U.S. EPA to promote purification of hazardous waste sites [38]. Development of the Chevron Questa mine began in 1920, and the mining there from 1965 to 1983 used an opencut system

Located about ten miles west of Empire, the Henderson Molybdenum Mine started production in 1976 after a decadelong development process. 1. 2. Located about nine miles west of Empire, the Henderson Molybdenum Mine was developed by American Metal Climax (AMAX) and opened in 1976 to work one of the world’s largest known molybdenum
Molybdenum is present as an accessory mineral in many sandstonetype uranium deposits of Arizona, Utah, Colorado, New Mexico, Wyoming, South Dakota and Texas. The molybdenum content varies from a few ppm to 0.5%, and it has been recovered from a few deposits as a byproduct of uranium mining. Molybdenum also occurs in
Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. The most important ore source of molybdenum is the mineral molybdenite; a minor amount is
In 1981 the mine started to cut production and lay off workers. After suspending production for a month in July 1982, the mine stopped production indefinitely that September. In 1983 parent company AMAX reopened the nearby Henderson Molybdenum Mine as prices recovered, but the company kept Climax closed because of its high
