What is Molybdenite?

Molybdenite is the primary ore for the metal molybdenum. This is a principal material for producing specialty alloys, making them more resistant to corrosion and heat as well as harder and stronger. Molybdenite has physical similarities with graphite, causing the two to be confused. It is also used in electronics and for semiconductor and transistor material.

Uses & Applications

Molybdenite is typically used to make alloys like steel, which has many applications such as engines, heating elements, and saw blades. It conducts electricity, strengthens the metal it is added to, and is resistant to corrosion. It is also a lubricant additive, used in the ink for circuit boards and other pigments.

Healing Properties

Molybdenite is believed to empower creativity and encourage new ideas while providing a smooth passage necessary for achievement. This stone may encourage self-awareness, boost confidence, and enable one to shun old methods of thinking or patterns of bad behavior. It is connected to all of the chakras to promote health and well-being.

Key Characteristics

Formation of Molybdenite

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 element rhenium is always present in molybdenite as a substitute for molybdenum, usually in the parts per million (ppm) range, but often up to 1–2%. High rhenium content results in a structural variety detectable by X-ray diffraction techniques. Molybdenite ores are essentially the only source for rhenium. The presence of the radioactive isotope rhenium-187 and its daughter isotope osmium-187 provides a useful geochronologic dating technique.
