How Is Molybdenum Mined and Processed? - Refractory Metals and Alloys

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.
