The world’s largest producers of molybdenum materials are the United States, Canada, Chile, Russia, and China. Though molybdenum is found in such minerals as wulfenite (PbMoO4) and powellite (CaMoO4), the main commercial source of molybdenum is molybdenite (MoS2). Molybdenum is mined as a principal ore, and is also recovered as a byproduct of copper and tungsten mining. 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.

All India total resources of molybdenum ore as on 1-4-2005 (provisional) are 19.28 million tonnes in which the contained MoS2 is 12,639 tonnes. Out of total resources of ore 1.5 million tonnes (7.78%) with a metal content of 1,050 tonnes are under Reserve category and the balance 92.22% ore are under Remaining Resources category. Out of the total resources 8 million tonnes of ore with 5020 tonnes of MoS2 are under leasehold all in public sector.
Molybdenum is generally found to be associated with copper, lead and zinc ores. In India by-product concentrates of molybdenum are produced intermittently from uranium ore of Jaduguda mine of Uranium Corporation of India Ltd. In Jharkhand.
