Mini Falcon Fine Gold Concentrator (2–3 TPH)

The Mini Centrifugal Gravity Concentrator is a compact enhanced gravity separation device designed for recovering fine and ultra-fine heavy minerals from slurry.
It operates using high centrifugal force generated by a rotating bowl to separate free heavy minerals such as gold from lighter materials. The system is particularly suitable for small-scale mining, laboratory testing, and field applications.
It is designed to work without chemicals, using only water and electrical power, making it environmentally friendly.

WORKING PRINCIPLE

• The concentrator uses centrifugal force (enhanced gravity) to separate minerals based on density.

Process Flow :

• Slurry enters the rotating bowl
• Bowl rotation creates high centrifugal force
• Material is classified by density

Heavy particles :

• Move outward
• Get trapped in riffles/grooves

Light particles :

• Discharge as tailings

After a cycle :

• Concentrate is rinsed out

Key Concept :

Combines :

• Classification (size separation)
• Centrifugal concentration
• Enables recovery of particles not captured by traditional methods

OPERATION CYCLE

Typical Cycle :

• Feeding time: ~1 hour
• Rinse time: 1–1.5 minutes

Rinsing Steps :

• Stop feed
• Reduce speed
• Open rinse water
• Collect concentrate
• Resume operation

INSTALLATION & OPERATION REQUIREMENTS

Requirements :

• Stable foundation
• Electrical power supply
• Clean pressurized water supply
• Slurry feeding system
• Tailings discharge system

Water Supply :

• Must be pressurized and consistent
• Should pass through ~50 mesh (not heavily contaminated)

LIMITATIONS

• Limited capacity (small-scale unit)

Performance depends on:

• Feed size

• Proper classification

• Mineral liberation

• Requires periodic cleaning (batch operation)

Mining Applications

• Hard rock gold processing
• Alluvial / placer mining
• Dredging operations
• Reprocessing of tailings

Processing Uses

• Initial ore concentration
• Upgrading of concentrates
• Pre-concentration before further processing
