2019 Minerals Yearbook
u.S. molybdenum reserves were estimated to have been about 2.7 million metric tons (Mt) in 2019, about 15% of world molybdenum reserves. About 90% of u.S. reserves occur in large, low-grade porphyry molybdenum deposits mined or anticipated to be mined primarily for molybdenum and in porphyry copper deposits as an associated metal sulfide. These
Elements in focus: molybdenum
In the West, molybdenum's first industrial use came in the late 19th century as a substitute for tungsten in steel-making. By the time of World War I, tungsten supplies were so depleted that molybdenum started being mined on a large scale, particularly in the USA. The main source was the mine at Climax, Colorado, USA.
Henderson Molybdenum Mine

Molybdenum processing
Ball or rod mills crush and grind the mined ore to fine particles, releasing molybdenite from the gangue (worthless rock). ... The chemical reduction of pure molybdenum xide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process.
Thompson Creek Molybdenum Mine, US
This style, primarily found in veins at shallow depths, has been mostly mined out. The dominant alteration at depth includes coarse biotite with some molybdenite found in quartz veins. Mineralisation is largely limited to the granodiorite/quartz monzonite intrusion. The structure is generally elliptical. The molybdenum mineralisation is found ...
