Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)

Shaking tables are very efficient in recovering heavy minerals from minus 100 microns (150 mesh) down to 5 microns in size. Heavy minerals of a size greater than 150 mesh are better run through a jig.

tures of the strips, the operating principle of the table head, and the installation method. Depending on the particle size of the process-able material,shaking tables canbeclassified into ore sand shaking table (0.074–2 mm) and slime shaking table (less than 0.074 mm). Ore sand shaking table can be classified into coarse sand

The principle of separation is based on the thin film concentration process across an inclined table having an asymmetric periodic motion to allow the selective stratification of particles according to their densities, sizes and shapes (Sivamohan and Forssberg, 1985b). The main operating parameter is undoubtedly the deck angle, which …

Beneath the table are mechanical devices called actuators that work together to simulate an earthquake. Typically, two actuators shake the table along the X axis, two shake the table along the Y axis, and four shake the tables vertically along the Z axis. The tables can also rotate independently along each of these three axes.
