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.

Mining methods used at the Canadian molybdenum mine. Molybdenum from the mine is planned to be recovered through open-pit operations. Shovels, loaders and haul trucks will be used for the mining.Molybdenum is obtained from two different types of mines primary mines and by-product mines. At primary mines its recovery is the prime target of the mining operation. Climax Molybdenum Company, a subsidiary of Freeport-McMoRan, has two primary mines in Colorado, with the Henderson mine currently operating half a mile under the Continental Divide.

    Acute molybdenum toxicity is rare, but it can occur with industrial mining and metalworking exposure. In healthy people, consumption of a diet high in molybdenum usually does not pose a health risk because the molybdenum is rapidly excreted in urine 1 , 14 , 18 .Acute molybdenum toxicity is rare, but it can occur with industrial mining and metalworking exposure.

Mining provides most of the supply, although the United States Geological Survey USGS estimates the quantity recovered from recycling may be asLevels of molybdenum in drinking-water do not usually exceed 10 gl Greathouse amp Osborne, 1980. However, in areas near molybdenum mining operations, the molybdenum concentration in finished water was reported to be as high as 200 gl. Tapwater concentrations as high as 580 gl have been reported in Colorado Chappell, 1973.

    The Henderson mine is a porphyry molybdenum deposit, with molybdenite as the primary sulfide mineral. The Henderson operation consists of a large block-cave underground mining complex feeding a concentrator with a current capacity of approximately 32,000 metric tons per day.The Henderson mine is a porphyry molybdenum deposit, with molybdenite as the primary sulfide mineral. The Henderson operation consists of a large block-cave underground mining complex feeding a concentrator with a current capacity of approximately 32,000 metric tons per day.Molybdenum is a chemical element with the symbol Mo. Pure molybdenum exists as a dark-gray or black powder with a metallic luster or as a silvery-white mass. It does not occur naturally in the pure metallic form. It is principally found as oxide or sulfide compounds. Therefore, almost all exposure is to a molybdenum compound rather than the actual metal alone.Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep about 1 km. The mining rate is greater than 20,000 tonnes per day tpd but is usually much greater. Some pits operate at a rate of more than 100,000 tpd
