Gold processing involves crushing, grinding, and beneficiation to extract pure gold from ore. Key equipment includes jaw crushers, cone crushers, ball mills, and gravity separators. For sand and aggregate production linked to gold mining waste, a crushing-screening line is often integrated.
A typical setup comprises:
1. Primary Jaw Crusher: Processes raw ore (e.g., PE600×900, capacity 50–160 t/h).
2. Secondary Cone Crusher: Fine crushing (e.g., HP300, max feed size 230mm).
3. Sand Maker: Produces 0–5mm sand (e.g., VSI1140, output 70–585 t/h).
4. Vibrating Screen: Multi-layer sorting (e.g., 3YK3070, screening area 7.5m²).
| Equipment | Model | Key Parameter |
|---|---|---|
| Jaw Crusher | PE750×1060 | Feed size: 630mm |
| Cone Crusher | HPT300 | Capacity: 120–440 t/h |
| Sand Maker | VSI6X1263 | Motor power: 315kW |
Q1: How to reduce dust in crushing?
A: Use water sprays or install bag filters.
Q2: What’s the lifespan of crusher wear parts?
A: Manganese steel jaws last ~6 months under normal use.
Project: Tanzania Gold Mine Tailings Recycling
– Scope: Processed 500t/day waste rock into construction sand.
– Solution: Deployed PE600×900 jaw crusher + HST160 cone crusher + VSI5X1145 sand maker. Achieved 30% cost savings vs. new quarrying.
This setup ensures efficient gold ore processing while converting waste into marketable aggregates.
