Small-scale gold ore flotation requires compact, cost-effective equipment tailored for lower throughput operations. Here’s a concise guide:
Key Equipment for Small-Scale Gold Flotation
1. Jaw Crusher (5–10 TPH)
– Primary crushing to reduce ore size (~10–50 mm).
2. Hammer Mill/Ball Mill (0.5–2 TPH)
– Fine grinding to liberate gold particles (target: 75–150 microns).
3. Spiral Classifier or Hydrocyclone
– Controls particle size by removing oversize material.
4. Flotation Cells
– Mechanical Agitation Cells: 0.05–1 m³ capacity (e.g., Denver D12 lab-scale or XFD/XCF series).
– Pneumatic Cells: Microcel columns for finer bubbles (optional). 
5. Reagent System
– Frothers (e.g., MIBC), collectors (xanthates), and pH modifiers (lime).
6. Concentrate Handling
– Filter press or small settling tank for dewatering.
7. Optional: Gravity Pre-Concentration
– Shaking table or centrifugal concentrator (Knelson/Falcon) before flotation to reduce feed volume.
Considerations
- Power Supply: Diesel generators if grid power is unreliable.
- Modular Design: Containerized units for mobility (e.g., Yantai or Jiangxi small-scale setups).
- Cost: Budget ~$20,000–$100,000 depending on automation level.

For refractory ores, consider roasting/cyanidation post-flotation. Always test ore samples first! Let me know if you need details on specific components.
