How Is Molybdenum Mined and Processed? Refractory Metals ...

Molybdenum exists in many minerals, but only molybdenite (MoS2) is suitable for the industrial production of molybdenum products. Molybdenite may be the only mineralized mineral in a single ore body, but it usually co-exists with other metals, especially copper sulfide minerals. The molybdenum content of each ore body is between 0.01 and 0.25%.

Production of Ferro Molybdenum. Opportunities in ...

definition of the Ferro Molybdenum production process would be that the Molybdenum is first mined and then transformed into Molybdenum (VI) Oxide MoO3. That oxide is mixed with iron oxide and aluminium and then reduced in an aluminothermy reaction. Electron-beam melting then purifies the Ferro Molybdenum, or the product can be packaged as-is.
