Wilfley Table (<0.5 TPH)

The Industrial Shaking Table (Gravity Concentration Table) is a high-capacity gravity separation device used for separating minerals based on differences in specific gravity (density).
It operates using a combination of reciprocating motion and water flow, allowing heavy minerals to concentrate while lighter materials are washed away. The table is widely used in mineral processing plants for final concentration and cleaning stages.
It is especially effective for recovering precious metals and other dense minerals from low-tonnage streams or fine particle circuits.

WORKING PRINCIPLE :

The shaking table separates minerals using:

• Reciprocating motion (back-and-forth stroke)
• Water flow across the inclined deck

Process Flow :

• Slurry feed enters the deck
• Water flows across the surface
• Motion causes stratification:
• Heavy particles → move toward concentrate side
• Light particles → move toward tailings
• Products are separated into:
• Concentrate
• Middlings
• Tailings
• Slimes

Key Concept :

• Separation based on:
• Density
• Particle size
• Motion dynamics on deck

PERFORMANCE ADVANTAGES :

• Produces high-grade concentrates
• Handles a wide range of particle sizes
• Effective for complex ores with mixed densities
• High throughput compared to lab-scale tables
• Reliable and widely used in industry

PROCESSING BEHAVIOR (IMPORTANT CONCEPT) :

Product Streams :

• Concentrate → mostly heavy minerals
• Middlings → mixed particles
• Tailings → light waste
• Slimes → very fine particles

Feed Preparation Options :

• Direct feed (natural size distribution)
• Sized feed (by screening)
• Classified feed (by hydraulic classification)

LIMITATIONS :

• Loss of very fine particles (slimes)
• Efficiency depends on:
• Feed size distribution
• Proper water control
• Operator skill
• May require additional circuits for middlings treatment
