ABSTRACT Enhanced gravity, or centrifugal, separators have revolutionised gold processing over the past decades, significantly increasing the recovery of fine (−100 μm) free gold. One of the main drawbacks of centrifugal gravity concentrators is the large volume of water required …

Gravity Concentration | Gekko

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

Gravity Separation - ScienceDirect

Gravity Separation Operations. Gravity concentrating operations are characterized by processes that allow particles to be held slightly apart so that they can move relative to each other and therefore to separate into layers of dense and light minerals.
