Designing a 20 tons per hour (tph) mixed rock tin tantalite ore processing plant requires careful consideration of multiple stages and types of equipment to effectively extract and refine the desired minerals. Here’s a suggested flow layout:
1. Crushing & Screening
- Jaw Crusher: Primary crushing of raw ore to reduce its size.
- Cone Crusher or Impact Crusher: Secondary crushing for further size reduction.
- Vibrating Screen: To classify material into different sizes for further processing.
2. Grinding
- Ball Mill: For grinding the crushed ore to achieve the desired particle size for mineral liberation.
- Spiral Classifier: To classify the ground material based on particle size.
3. Gravity Separation
- Shaking Table: For the initial concentration of tin and tantalite particles.
- Jig Concentrator: To improve the recovery of coarse tin and tantalite.
- Spiral Chute: For further concentration of fine particles.
4. Magnetic Separation
- Magnetic Separator: To remove any magnetic minerals and further purify the concentrate.
5. Flotation
- Flotation Cells: For further refining and enhancing the quality of the concentrate.
6. Thickening & Filtration
- Thickener: To concentrate the slurry and remove excess water.
- Filter Press: To de-water the concentrate for easier handling and shipment.
7. Sorting & Drying
- Optical Sorter: For additional refinement and separation based on material properties.
- Dryer: To ensure the final product is sufficiently dry.
Ancillary Equipment:
- Feeders: To maintain continuous material flow through the plant.
- Pumps and Piping: For slurry and water management.
- Control System: Automated system to monitor and optimize operations.
Notes:
- Water and Power Supply: Ensure adequate resources to support the entire operation.
- Environmental Considerations: Implement necessary measures for waste management and minimize environmental impact.
Summary
- Capacity: 20tph
- Products: Tin and Tantalite Concentrates
- Efficiency: Maximized through multi-stage processing
Careful planning and design, combined with the use of modern, efficient equipment, will ensure the successful setup and operation of the plant. It's also important to routinely monitor and maintain equipment to ensure peak performance. Consulting with experts in mineral processing and plant engineering can further fine-tune the setup for optimal results.
