For small-scale rock crushing and sand production, portable gold processing plants often utilize compact jaw crushers, hammer mills, and roller crushers. Key equipment includes:
– Mini Jaw Crusher (PE-150×250)
Feed Size: ≤125mm | Output: 1-3t/h | Power: 5.5kW
– Hammer Crusher (PC400×300)
Feed Size: ≤100mm | Output: 5-10t/h | Power: 11kW
– Trommel Screen + Centrifugal Concentrator
Processing Capacity: 2-5t/h | Gold Recovery Rate: >90%
A typical 20t/h mobile aggregate plant for gold-bearing quartzite processing might include:
| Equipment | Model | Key Parameters |
|——————–|————-|——————————-|
| Vibrating Feeder | GZD-650×2300| Capacity: 20-80t/h |
| Jaw Crusher | PE-250×400 | Discharge: 20-60mm |
| Cone Crusher | PYB600 | Output Sand: 0-5mm |
| Sand Maker | VSI-7611 | Finished Sand Ratio: 40% |
Q1: What’s the minimum setup area for a portable crushing line?
A: ~15m×20m for a complete circuit including stockpile zones.
Q2: How to prevent dust in dry processing?
A: Install water spray nozzles at transfer points + pulse dust collectors.
A client processed oxidized gold ore (Au grade: 3.5g/t) using our modular plant:
– Flow: Two-stage crushing (Jaw+Roll) → Grinding → CIP leaching
– Result: Achieved 86% recovery rate with <8% -200mesh overgrinding.
(Note: All equipment specs are based on real-world configurations; actual performance varies by material hardness and moisture content.)
