Gold shaking tables are basically low-capacity machines used as the last step in the gold upgrading process. The shaking table is a thin film, shear flow process equipment, which separates particle grains of its feed material based on the differences in their specific gravity, density, size, and shape. Mineral-rich particles, that from light to heavy and fine to coarse will be sorted by net effective weight.
Finely crushed or ground gold ore material goes as feed mixed with water to form a pulp mud and fed as a slurry of an average of about 20–25% of solids by weight onto the highest point of the table deck. The gold shaking table’s deck has a reciprocal movement along its main axis that is given using a vibrator or an eccentric head motion. The shaking table surface is manufactured and fitted with several tapered strips called riffles or grooves, often made with yellow pine, low-density polythene, or aluminum surfacing. Shaking tables and other thin film separating plant recover finely divided gold under conditions of subcritical laminar and supercritical laminar regimes of flow, which may occur only where there is a very thin depth of the fluid.
