2 ensp;0183;ensp;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 ].
A recommended daily allowance of molybdenum for an adult has been established at 0.2 mg [Dulce, 1968]. In addition daily molybdenum intakes from drinking water and ambient air are almost neglible and should be considered only in molybdenum mining areas.

223ensp;0183;ensp;Grades of Mo in mined ore deposits generally range between 0.10% and 0.25%. Molybdenum is mined as a primary product of Mo porphyry deposits, and as a byproduct of Cu porphyry and other types of Cubearing ores.

Levels of molybdenum in drinkingwater do not usually exceed 10 181;g/l (Greathouse amp; Osborne, 1980). However, in areas near molybdenum mining operations, the molybdenum concentration in finished water was reported to be as high as 200 181;g/l. Tapwater concentrations as high as 580 181;g/l have been reported in Colorado (Chappell, 1973).

We produce metals to meet societys needs with a commitment to sustainable development, part of which includes the land reclamation process. This process involves taking land once used in mining
