Molybdenite

A sulfide mineral of chemical composition. There are different types, belonging to the hexagonal and tripartite crystal systems. Containing 59.94% molybdenum, it is the most important mineral raw material for refining molybdenum. It often contains rhenium, and is the highest rhenium-containing mineral known in nature, as well as the most important mineral raw material for refining rhenium. Pyromolybdenite is lead gray, strong metallic luster. With complete bottom surface resolution. The crystals are hexagonal plate-like. It is usually produced in the form of flakes, scales or finely dispersed grains. Pyrrhotite is the most widely distributed molybdenum mineral, mainly produced in high and medium temperature hydrothermal and syenite deposits. It is easily weathered to molybdenite at the surface. Clay Marks and Euclid Henderson in Colorado, U.S.A., are the world-famous pyromolybdenum ore sources. China's Henan, Shaanxi, Shanxi, Liaoning and other provinces are also produced, the total reserves have jumped to the forefront of the world.
