Molybdenum Ore Beneficiation Process
The molybdenum ore beneficiation process includes several key stages that ensure efficient mineral recovery and high-grade concentrates. Here’s an overview:
1. Crushing and Screening
Molybdenum ore is first crushed using jaw crushers or double roller crushers to reduce large chunks into smaller, manageable sizes.
Vibrating screens remove oversized particles, ensuring uniform material for grinding.
2. Grinding and Classification
Crushed ore is sent to ball mills for fine grinding, turning it into fine powder.
Spiral classifiers or hydrocyclones then classify the ground material, separating fine particles for the next step.
3. Flotation
Flotation is the core process for molybdenum ore beneficiation. By adding flotation reagents, molybdenum minerals separate from impurities.
Froth containing molybdenum rises to the surface, forming the concentrate, while tailings are discharged.
4. Concentration and Filtration
The flotation concentrate undergoes thickening to remove excess water using a thickener.
Further dehydration is achieved with a filter press, resulting in low-moisture molybdenum concentrate.
5. Drying and Packaging
The filtered concentrate is dried in a rotary dryer.
Finally, the dry molybdenum concentrate is packaged and prepared for shipment or market use.
