A tantalum concentrate processing plant transforms raw ore into high-purity tantalum products through crushing, grinding, gravity separation, and refining. The core equipment includes jaw crushers, cone crushers, ball mills, and spiral classifiers. Tantalum’s hardness (6.5–7.5 Mohs) demands wear-resistant machinery with precise particle control (<1mm for leaching).
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-120 | 75 |
| Cone Crusher | HPT300 | 80-200 | 315 |
| Ball Mill | MQY2740 | 15-30 | 400 |
| Sprial Classifier | FG-12 |
High-frequency screens (e.g., YA2460) separate particles at 0.1–3mm, while shaking tables recover >90% Ta₂O₅ from -2mm feed. X-ray sorters enhance purity to 99% by removing Nb/Sn impurities.
– Q: How to reduce slime loss?
A: Use hydrocyclones + ultrasonic washing for -75µm particles.
– Q: Crusher liner lifespan?
A: Mn18Cr2 liners last 6–8 months for 500t/d throughput.
A 300tpd plant achieved 98% recovery using:
1. Two-stage crushing (PE400×600 + HST160)
2. Knelson concentrators for coarse Ta (>0.5mm)
3. Electrowinning for final Ta powder (99.95% purity).
