Molybdenite Mines

Molybdenite is also found in rocks that have been altered by contact and hydrothermal metamorphism. Much of the commercially produced molybdenite occurs as disseminated crystals in porphyry copper deposits where it is produced as a byproduct mineral. Lesser amounts are produced at mines where molybdenite is the primary product.

Molybdenite Crystals In Quartz From The Confianza Mine

This molybdenite is from the Confianza Mine, Tilma Coquimbo Region, Chile. This mine contains only two different minerals: quartz which is a silicate containng the elements Si and O and molybdenite which is a sulfide containing the elements Mo and S. Both minerals are represented in this specimen.

Molybdenite Wikipedia

Molybdenite occurs in high temperature hydrothermal ore deposits. Its associated minerals include pyrite, chalcopyrite, quartz, anhydrite, fluorite, and scheelite.Important deposits include the disseminated porphyry molybdenum deposits at Questa, New Mexico and the Henderson and Climax mines in Colorado.Molybdenite also occurs in porphyry copper deposits of Arizona, Utah, and Mexico.

The Petrology And Mineralogy Of The Whipstick

The Bega granite at Whipstick, N.S.W., consists of a granite metasomatically altered to leucogranites and a spessartite-granite. The ore occurs in pipes controlled by jointing and shows evidence of post-depositional tectonic forces. The principal ore minerals are molybdenite and bismuthinite, with minor amounts of uraninite, pyrite, gold, bismuth, joseite A, joseite B, tetradymite .
