Though molybdenum is found in such [[mineral]]s as [[wulfenite]] ([[lead|Pb]]Mo[[oxygen|O]]<sub>4</sub>) and [[powellite]] ([[calcium|Ca]]Mo[[oxygen|O]]<sub>4</sub>), the main commercial source of molybdenum is [[molybdenite]] (Mo[[sulfur|S]]<sub>2</sub>). Molybdenum is mined as a principal ore, and is also recovered as a byproduct of copper and tungsten mining.<ref name="CRCdescription" /> Large mines in [[Colorado]] ([[Climax, Colorado|Climax]]) and in [[British Columbia]] yield [[molybdenite]], while many [[porphyry copper]] deposits such as the [[Chuquicamata]] mine in northern [[Chile]] produce molybdenum as a byproduct of copper mining. The Knaben mine in southern Norway was opened in 1885, making it the first molybdenum mine. It remained open until 1973.
Molybdenum is the 42nd-most-abundant element in the universe, and the 25th-most-abundant element in Earth's oceans, with an average of 10.8 mt/km³.<ref name="Nostrand" /> The Russian [[Luna 24]] mission discovered a single molybdenum-bearing grain (1
A side product of molybdenum mining is [[rhenium]]. As it is always present in small varying quantities in molybdenite, the only commercial source for rhenium is molybdenum mines.
