What is the working principle of a gold centrifugal concentrator?

Gold centrifugal concentrator primarily utilizes centrifugal force to enhance the gravity separation process.

The working principle of the gold centrifugal concentrator is as follows: The ore slurry enters the high-speed rotating centrifuge drum through the feed pipe. Under the action of centrifugal force, minerals with different specific gravities in the slurry will have different settling velocities. Gold and heavy minerals with higher specific gravity will overcome the reverse resistance of the centrifugal liquid flow and settle on the inner wall of the drum, forming a heavy mineral layer; while lighter minerals with lower specific gravity will flow towards the center of the drum under the action of the centrifugal liquid flow and be discharged. By periodically discharging the heavy mineral layer, a gold-rich concentrate can be obtained.
