The name derived from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. [12] Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele.
Peter (Petter) Jacob Hjelm (2 October 1746 – 7 October 1813) was a Swedish chemist [1] and the first person to isolate the element molybdenum in 1781, four years after its discovery by Swedish chemist Carl Wilhelm Scheele.
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
Chemical elements are sometimes named after people, especially the synthetic elements discovered (created) after c. 1940. Very few are named after their discoverers, and only two have been named after living people: the element seaborgium was named after Glenn Seaborg , who was alive at the time of naming in 1997; [ 5 ] and in 2016 oganesson ...
Molybdenite is an important ore of molybdenum, and is the most common source of the metal. [4] While molybdenum is rare in the Earth's crust, molybdenite is relatively common and easy to process, and accounts for much of the metal's economic viability. Molybdenite is purified by froth flotation, and then oxidized to form soluble molybdate ...

At its highest output, the Climax mine was the largest molybdenum mine in the world, and for many years it supplied three quarters of the world's supply of molybdenum. After a long shutdown, the Climax mine reopened and resumed molybdenum shipment on May 10, 2012. The mine is owned by Climax Molybdenum Company, a subsidiary of Freeport-McMoRan.
