Gravity separation is a physical process which consists of the separation of different mineral types in the ore from one another based on differences in their specific gravities using the force of gravity, which can be influenced by one or more of other forces such as centrifugal force, resistance to motion by a fluid (e.g. air, water) etc ...

Shaking tables, also known as concentrating tables, are devices that leverage the principles of gravity, vibration, and water flow to separate minerals from ore streams. They consist of a slightly inclined deck covered with riffles where the ore mixture is introduced. The process begins with the ore slurry fed onto the shaking table's deck.
