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.
