yes its a metal
WULFENITE IS USE AS A MINERAL SPECIMEN OR AS A MINERAL ORE OF MOLYBDENUM

Molybdenum is not a rock, but rather a mineral. It is a chemical element, as well. It has the 6th highest melting point of all the elements, and is used in high strength steel. Molybdenum is also a vital mineral in higher animals.
Mineral resources such as copper, coal, tin, gold, molybdenum, tungsten.
Molybdenum was first identified as a new element in 1778 by C W Scheele who produced molybdenum oxide from molybdenite, MoS2, mineral which until then has been believed to be identical to graphite. The metal molybdenum was first isolated in 1781/1782 by P.J. Hjelm.
The mineral with the smallest daily requirement is typically molybdenum, which is needed in very small amounts. The recommended dietary allowance (RDA) for adults is about 45 micrograms per day. Despite its low requirement, molybdenum plays a crucial role in various enzymatic processes within the body.
Deficiencies of molybdenum are rare, but do occur where the mineral is not present in soil, or in people with certain genetic disorders. When a deficiency occurs, it could cause esophageal cancer, impotence, and an abnormal excretion of sulfur.
Not in vitamins but in mixtures of vitamins, minerals and some other - alimentary supplements. For molybdenum see: http:/lpi.oregonstate.edu/infocenter/minerals/molybdenum. Is molybdenum safe to consume orally?
Wulfenite is a lead molybdate mineral that is primarily used as a collector's mineral and in jewelry for its vibrant orange-red color. It is also used in mineral specimens for research and educational purposes due to its distinctive crystal structure. Additionally, wulfenite has limited industrial uses, such as in the production of lead and molybdenum compounds.
The mineral with the lowest daily requirement is molybdenum, with a recommended daily intake of only 45 micrograms for adults. This mineral is essential for various enzymatic functions in the body, despite being needed in such small amounts.
Although molybdenum is fairly abundant and is found in a number of minerals, its commercial production is primarily from mineral molybdenite, MoS2.The process involvesRoasting the ore - to give molybdenum oxide.This is extracted from the ore using aqueous ammonia, whence it forms ammonium molybdate.Ammonium molybdate is then converted to ammonium dimolybdate which can be isolated as a solid.Heating this gives molybdenum trioxide, MoO3.Finally, the metal is produced by reduction using hydrogen.
