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

Molybdenum Processing. 1. Grinding. A grinding machine crushes rocks the size of footballs to the size of gravel, then uses a ball mill to further reduce the material to the size of cosmetic powder. 2. Flotation. In the flotation process, the ground ore/gangue powder is mixed with a liquid reagent and inflated.

Molybdenum belongs to the group of refractory metals.

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.
