Molybdenum Mining - IMOA

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. The Mo content of viable ore bodies ...

Molybdenum in Drinking-water - WHO

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