DESCRIPTION
The ferromolybdenum manufacturing process begins with molybdenum being mined and transformed into molybdenum (VI) oxide (MoO3). MoO3 is mixed with iron oxide and aluminum and then reduced by an aluminothermy reaction.Electron-beam melting is applied to purify the ferromolybdenum. The final alloy product is produced in the form of small briquettes or fine powder. Ferromolybdenum is usually supplied in bags or steel drums.
