Fine Gold Recovery. Separating Placer Gold Particles from ...
Gold, being the heaviest element we typically encounter in a stream, can be separated from lighter materials by various gravity separation methods. Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold dredges, sluice boxes, drywashers, and many other types of equipment uses gravity separation to discharge lighter material while retaining gold.
Gold Mining Methods - groundtruthtrekking.org
The stereotypical grizzled gold-rush prospector panning for gold was searching for "placer gold", or gold deposited in a waterway. Placer mining takes a variety of forms, including panning, "sluice-boxing", hydraulic mining, and dredging. All of these techniques use gravity and water to separate the dense gold from the lighter sand and gravel.
