Choosing The Correct Gravity Separation Machine

There are several devices that use gravity separation for the purpose of heavy mineral and gold recovery. From simple jigs to high G-force gravity centrifuges, knowing which one to use for optimal mineral processing can be complicated and difficult to understand. There are so many factors to consider when creating the ideal circuit; one critical element is the size of the particles you intend to recover.

Gravity separation and Ore Beneficiation –

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. Hence, besides gravity, other factors, such as size, shape etc., also have an

Gravity beneficiation is a method of sorting ore in a certain fluid medium according to the difference in mineral density. The gravity separation process is carried out in a fluid medium, usually water, and sometimes heavy medium (heavy liquid or soliquiod). The essence of gravity separation processing is summarized as a loose-layered-separation process. The loose action of the fluid must obey the requirement of stratification of the granules.

The choice of the concentration process to be used in a mineral depends on the physical and chemical characteristics of the constituents to be separated. Gravity concentration can be defined as the process by which particles of different sizes, shapes, and densities are separated from each other by the force of gravity or the centrifugal force. The method is one of the oldest in mineral treatment. Its most primitive
