A complete copper ore processing line typically includes primary crushing, secondary crushing, grinding, and flotation systems. The crusher system reduces raw copper ore (typically 500-800mm) to ≤25mm particles for efficient flotation.
| Equipment | Model | Capacity | Power |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-160 t/h | 75 kW |
| Cone Crusher | HPT300 | 120-250 t/h | 220 kW |
| Ball Mill | MQY3660 | 15-20 t/h | 850 kW |
| Flotation Cell | XCF/KYF-24 | 15 m³/min | 45 kW |
Primary crushing → Secondary crushing → Screening → Grinding → Classification → Flotation → Concentrate dewatering. The final copper concentrate typically reaches 20-30% Cu grade.
Q: What’s the optimal feed size for flotation?
A: Generally ≤0.074mm accounts for 60-70%.
Q: How to improve crusher efficiency?
A: Maintain proper CSS (closed side setting) and regular liner replacement.
Q: Common flotation reagents?
A: Collectors (xanthates), frothers (MIBC), and modifiers (lime).
