Gold panning - Wikipedia

Gold panning is a simple process. Once a suitable placer deposit is located, some alluvial deposits are scooped into a pan, where they are then wetted and loosed from attached soils by soaking, fingering and aggressive agitation in water. This is called stratification; which helps dense materials, like gold, sink to the bottom of the pan.
