Molybdenum Ore Characteristics

Molybdenum is a transitional ferrophilic element in the geochemical classification. During endogenous mineralization, molybdenum combines mainly with sulfur to produce pyromorphite. Other more common molybdenum-bearing minerals include ferromolybdenite, calcium molybdate (CaMo), colored molybdenum-lead (PbMo), colloidal sulfur molybdenite (), and blue molybdenite (-nH2O).

Pyrrhotite () is the most widely distributed molybdenum mineral with real industrial value among more than 30 kinds of molybdenum-bearing minerals known in nature. Pyromolybdenite is lead gray, similar to graphite, with metallic luster, belongs to the hexagonal crystal system, the crystals are often in the form of hexagonal flakes, the bottom surface is often patterned, the texture is soft and slippery, and the flakes are thin and flexible. Specific gravity 4.7 ~ 4.8, hardness 1 ~ 1.5, melting point of 795 ℃, scratched on the ceramic plate streaks of light greenish gray or light greenish black, heating to 400 ~ 500 ℃ when it is easy to oxidize and generate, nitric acid and aqua regia can make molybdenum pyroxene ( ) decomposition. Pyromolybdenite Used in the production of molybdenum ferroalloys, metallic molybdenum, calcium molybdate, ammonium molybdate, lubricants and so on.
