Gold Recovery And How To Choose The Right

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. For deposits with high clay content, the rocks are cleaned with a trommel or rotary scrubber to remove contaminants, and then gold recovery can take place.

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
