Molybdenum belongs to the group of refractory metals and has a melting point of 2620 °C. Molybdenum is a by-product in the mining process of complex raw materials such as copper. The rest is mined in its own ores.
The main source is unroasted molybdenum concentrate (MoS2 or UMC) with 45% Mo, which comes in form of powder and it is the first commonly commercially traded product. Then unroasted molybdenum concentrate has to go through the roasting process in order to remove impurities such as Sulphur. After roasting is completed UMC becomes roasted molybdenum concentrate (RMC) with 57-64% Mo and it is produced in form of powder or briquettes. RMC is a very popular product which is commonly traded in the metal market.
Roasted molybdenum concentrate is a universal product, as it can be further processed into multiple derivatives. From roasted concentrate we produce our own Ferro-Molybdenum master alloy which is further used in molybdenum contained steels. Further roasted concentrate can be processed into pure oxide (MoO3 / PMO) which can be used for production of pure metal or Molybdenum-Chrome alloy.
Molybdenum products such as Ferro-Molybdenum, and roasted concentrate (in form of powder and briquettes) are commonly used in contained steels such as structural steel, stainless steel and tool steel. Moreover, pure metal or molybdenum-chrome alloy are also used in super-alloy applications, primarily in oil and gas, automotive and aerospace.
