What do they mine at Climax molybdenum?
Beside molybdenum, the mine has also produced tin (from cassiterite), tungsten (from hübnerite), and pyrite as by-products. The rocks of the Climax Stock are alkaline felsic intrusives. They range from porphyritic alkaline rhyolite to alkaline aplite to porphyritic alkaline granite.
Where is the largest molybdenum mine in the world?
The Climax mine, historically the world’s largest source of molybdenum, is north of Leadville, Colorado.
What does Climax molybdenum make?
Examples of oxidation processes using molybdenum catalysts include the production of formaldehyde from methanol and acrylonitrile or propylene oxide from propylene. Stable molybdate solutions with low impurity levels can be produced from the Climax Molybdenum Company range of molybdenum oxides and molybdates.
Who owns Henderson mine?
Freeport-McMoRan
Now owned by Freeport-McMoRan, the mine employs about 350 people and is expected to remain productive until the late 2030s.
How many molybdenum mines are there in the world?

What is molybdenum used for?
Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. These ‘moly steel’ alloys are used in parts of engines. Other alloys are used in heating elements, drills and saw blades.
