The difference between the specific gravity of gold (19.0) and the low specific gravity of the gangue (2.7) makes gravity concentration the primary means of recovery free gold particles. In general, gravity separation has some advantages over flotation and leaching, it needs significant lower capital investment, less power and low handling costs.

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the "concentrates," in which …
The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation …

A Gravity Chute is a conveyance system that uses the force of gravity to move materials from one level to another. It is a simple and cost-effective method of transporting bulk materials such as grains, powders, and small objects in a controlled manner. Gravity Chute are typically used for vertical or inclined transportation, allowing materials to move downward due to the force of …
