<p>The invention provides a jig (10) for separating particles with different densities from a feed material. The size of the jig may vary depending on the application, and in some embodiments the jig is portable and is bolted to a metal frame (12). Typically a discharge chute (14) discharges a particulate material onto a pair of parallel conveyor belts (16). The conveyor belts discharge the feed material into a feed end (18) of the jig. The slurry moves from the feed end towards a discharge end (20) in the direction indicated by the arrow 'A'. The separation is achieved by pulsing a fluid medium perpendicularly to the direction arrow 'A' at a desired frequency while maintaining fluid flow in an upward direction at all times.</p> |
