Molybdenite: Mineral information, data and localities.

Variations of the name molybdaena and molybdenite were used for lead ores by Dioscorides (50-70 CE), Pliny the Elder (79 CE), and Agricola (1556), but the modern use of molybdenite did not begin until Johan Gottschalk Wallerius wrote about molybdenite in Mineralogia, eller Mineralriket published in 1747.

2018-5-2  Molybdenite is the most important source of molybdenum, which is an important element in high-strength steels. Molybdenite was originally thought to be lead, and its name is derived from the Greek word for lead, molybdos. It was recognized as a distinct mineral by the Swedish chemist Carl Scheele in 1778. Molybdenite is soft, opaque, and bluish gray.

Molybdenite - an overview ScienceDirect Topics

Molybdenum does not occur in metallic form in nature. It is mainly present in the minerals such as molybdenite (MoS 2), wulfenite (PbMoO 4), and powellite (CaMoO 4), from which it can be extracted. Most of the molybdenum mines are located in the United States of America, China, Chile, Canada, Peru, Russia, Armenia, and Mexico, with the largest mine being at Climax, Colorado, United States of America.
