The Compact Shaking Table with Magnetic-Assisted Separation is a gravity concentration device designed for recovery of fine gold and heavy minerals, especially from materials containing magnetite and black sand.
It combines traditional shaking table principles with magnetic separation, allowing improved recovery of micron-sized gold particles. The system is compact, portable, and suitable for small-scale mining, laboratory work, and field operations.
WORKING PRINCIPLE :
The system works using a combination of :
- Shaking table motion (gravity separation)
- Magnetic repulsion (reverse polarity)
Process Flow :
- Feed material is introduced onto the table
- Water flows across the deck
- Shaking motion stratifies particles
- Magnetic system acts on magnetite:
- Magnetite is repelled and moves to tailings
- Gold particles:
- Freed from magnetite
- Move toward concentrate zone
Key Concept :
- Magnetic repulsion removes interfering magnetite
- Improves recovery of fine gold particles
PERFORMANCE ADVANTAGES :
- Enhanced recovery of micron gold
- Effective separation of magnetite from gold
- Reduces losses caused by black sand interference
- Portable and easy to operate
- Suitable for remote and off-grid use
LIMITATIONS :
- Limited capacity (small-scale unit)
- Requires pre-screened material (no built-in screening)
- Performance depends on:
- Feed consistency
- Water flow control
- Not suitable for large-scale industrial processing
INSTALLATION & OPERATION NOTES :
Requirements :
- Water supply (preferably recycled system)
- Small generator or power source
- Pre-screened feed material
Important Notes :
- No screening system included (external screening required)
- Large water reservoir recommended
- Proper setup improves efficiency significantly
KEY CONCEPT :
- Reverse Polarity Magnetic Separation
- Magnetite is repelled instead of attracted
- Gold is freed and recovered more efficiently
