unusual facts about molybdenum



Climax mine

The prospector Charles Senter discovered and claimed the outcropping of molybdenite (molybdenum sulfide) veins in 1879, during the Leadville, Colorado, Silver Boom, but he had no idea what the mineral he found was.

Other molybdenum deposits in the region include the Questa mine in New Mexico, and the Henderson and Urad mines near Empire, Colorado.

Frank Kasper phases

While addition of refractory elements like W, Mo or Re to FK phases helps to enhance the thermal properties in such alloys as steels or nickel-based super alloys, it increases the risk of unwanted precipitation in intermetallic compounds.

Kitsault, British Columbia

The later town of Kitsault was established in 1979 as the home community to a molybdenum mine run by the Phelps Dodge corporation of the United States.

Molybdenite

Important deposits include the disseminated porphyry molybdenum deposits at Questa, New Mexico and the Henderson and Climax mines in Colorado.

Olefin metathesis

Giulio Natta in 1964 also observed the formation of an unsaturated polymer when polymerizing cyclopentene with tungsten and molybdenum halides.

Teghut Mine

Teghut Mine is a proposed copper and molybdenum open-pit mine in Armenia's northern province of Lori in the village of Teghut.
