Enhanced Gravity Concentration for Precious Metal Recovery

Enhanced gravity concentration machines recover gold that is easily lost on shaking tables. For this reason, batch-type centrifugal concentrators are seeing growing use as a scavenger for tables. Cadia reported a ±20% increase in gravity gold production after installing a Falcon on table tailings. The scavenger concentrate must be re-tabled.

Gold Recovery with Centrifugal Gravity Concentrator

Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks.

Spirals increased net recovery by 4-6% but the need for much operator attention was a problem. When they were replaced by a B20, recovered metal rose to one kg of gold per three kg of jig recovery. A changing feed type with lower gravity gold and new flotation strategies prevented quantifying the net effect on recovery.
