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 recovered from the mineral wulfenite. Molybdenum commonly is recovered as a by-product or co-product from copper mining.

The appeal centered around the Mount Hope Molybdenum Mine, which is located about 25 miles northwest of Eureka. Great Basin Resource Watch, a nonprofit environmental advocacy group, appealed the state's decision to renew the permit for Eureka Moly, a subsidiary of General Moly, arguing that the state used flawed analysis in approving the ...
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 deposits.A conveyor belt for transporting ore connects the mine to a separate mill on the western side of the Continental Divide, whose location was chosen because of space constraints and …
Thompson Creek Mine. The Thompson Creek Mine is a primary, surface molybdenum mine and mill located approximately 48 kilometres southwest of the town of Challis in Idaho's Custer County.
