Gold Recovery And How To Choose The Right Process
Panning for gold can be great fun but is not very practical for gold recovery on a large scale. The most cost-effective gold recovery solution for placer deposits is using a gravity concentration circuit. First, the material is screened to remove large rocks and boulders. Then a sluice or jig is used to recover the gold.
