Black sand gold separator machines are specialized equipment designed to extract fine gold particles from heavy mineral concentrates, often integrated into sand and gravel processing lines. These machines enhance resource recovery while maintaining aggregate quality.
1. Vibrating Feeders: Pre-sort raw materials (Capacity: 50-500t/h)
2. Trommel Screens: Separate oversized rocks (Screen size: 3-20mm)
3. Spiral Classifiers: Wash and grade sand particles (Slope: 14-18°)
4. Centrifugal Concentrators: Recover gold (G-force: 60-200G)
| Model | Processing Capacity | Power | Gold Recovery Rate |
|---|---|---|---|
| GS-100 | 5t/h | 7.5kW | >95% (50-100 mesh) |
| GS-200 | 15t/h | 22kW | >92% (30-150 mesh) |
| GS-500 | 30t/h | 45kW | >90% (20-200 mesh) |
A typical setup for processing gold-bearing black sand:
Raw material → Grizzly screen → Jaw crusher → Cone crusher → Trommel washer → Spiral separator → Gold concentrator → Tailings management
Q: How to prevent gold loss during crushing?
A: Use rubber-lined crushers and minimize water use in primary stages.
Q: What’s the optimal feed size for concentrators?
A: Typically 3mm minus, with clay content below 15%.
Q: Can this equipment process hard rock ores?
A: Requires additional ball mills and different screening systems.
