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.
