Molybdenum | chemical element | Britannica

Molybdenum is not found free in nature. A relatively rare element, it is about as abundant as tungsten, which it resembles.For molybdenum the chief ore is molybdenite—molybdenum disulfide, MoS 2 —but molybdates such as lead molybdate, PbMoO 4 (wulfenite), and MgMoO 4 are also found. Most commercial production is from ores containing the mineral molybdenite.
