Gold Recovery And How To Choose The Right Process

Gold can be found almost anywhere on the planet, and the key to recovering it is knowing what type of gold it is. Gold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock.
