Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, from Ancient Greek Μ?λυβδο? molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various
Mining Molybdenum is contained in various minerals, but only molybdenite (MoS 2 ) is suitable for the industrial production of marketable molybdenum products. Molybdenite can occur as the sole mineralization in an ore body, but is often associated with the sulphide minerals of other metals, notably copper.
Molybdenum exploration in Canada is heating up along with demand for the metal. Miners are looking to take advantage of China’s appetite for steel, for which moly is a vital ingredient.
This list of molybdenum mines is subsidiary to the list of mines article and lists working, defunct and planned mines that have substantial molybdenum output, organized by country.
Fresh from closing a $518 million acquisition, metals firm China Molybdenum Co (CMOC) remains open to deals that would boost business in the booming electric vehicle (EV) battery sector, the
The Climax Mine near Leadville began reopening in 2008, but when the price of molybdenum dropped from more than $30 per pound less than $10 per pound in a few weeks, the reopening was suspended. At least two additional major deposits in Colorado are known; the Lucky Jack depositin Gunnison County and a large deposit at the old mining town of
The Thompson Creek Mine is a primary, surface molybdenum mine and mill located approximately 35 miles southwest of the town of Challis in Idahos Custer County. The mine, which began operations in 1983, uses conventional open-pit mining methods with large electric-powered shovels that can each move up to 100,000 tons of waste rock and ore per day.
Thompson Creek Metals expects to reach approximately 60,000 tpd by the end of 2015 by utilizing temporary crushing. Thompson Creek Mine (near Challis, Idaho) — The Thompson Creek Mine is a primary molybdenum mine located approximately 35 miles southwest of Challis in Idahos Custer County, a historic mining area. Known as the Thompson Creek
The main ore bearing area was Bartlett Mountain, which was mined out during the early mining. The demand for molybdenum fell drastically at the end of World War I, and the Climax mine shut down in 1919. Molybdenum later found use in the metal alloys for the turbines of jet engines. Molybdenum is an important metal used in industrial work to increase the resistance of steel because of its much higher melting point compared to that of iron.
Among the base metal and precious metal deposits, there are 7 copper-molybdenum mines, 3 copper mines, 13 gold and gold-polymetallic mines, 2 polymetalilc mines and 2 iron ore mines.  In addition to those mines registered in the state inventory of mineral resources, there are an additional 115 deposits of various deposits that have been discovered.

The name is from Neo-Latin molybdaenum, from Ancient Greek Μ?λυβδο? molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element . Early molybdenum steel alloys showed great promise of increased hardness

Molybdenum mining and processing techniques have been improved continuously since the first mine was started at Climax near Leadville, Colorado in 1916.
Molybdenum (element #42, symbol Mo) is a metallic, lead-gray element, with a high commonly is recovered as a by-product or co-product from copper mining. It is alloyed with steel making it stronger and more highly resistant to heat.
When alloyed with other metals, molybdenum promotes hardenability and Although the metal was known to ancient cultures, and its mineral forms were Roughly 40 percent of molybdenum comes from primary mines, with the other 60
