The centrifugal concentrator rotates at a high speed, generating a high "G" force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables. In recent years, the application of centrifugal force has proved to be an effective technology for recovering fine and heavy minerals.
