Ore Reserves

Reserve Base

Molybdenum is only known to occur in a natural state chemically combined with other elements. Although a number of molybdenum-bearing minerals have been identified, the only one of commercial significance is molybdenite (MoS₂) - a natural molybdenum sulfide. In ore bodies, molybdenite is generally present in quantities from 0.01-0.25% and is often associated with the sulfide minerals of other metals, notably copper.
