How Is Molybdenum Mined and Processed? Refractory Metals ...
Sep 05, 2019 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.

Mineralogical Prediction on the Flotation Behavior of ...
This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then process them using flotation.

Molybdenum Processing - IMOA
The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.

Copper-Molybdenum ores - Danafloat
Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
