ABSTRACT:
A portable sluice pan is described for panning for gold and other valuable heavy minerals from placer deposits. The pan includes an elongated trough having a feed hopper at one end and a removable flexible riffle mat in the bottom of the trough to cause the placer pulp to flow in a turbulent manner over the riffles to stratify the heavier and lighter materials. The sluice pan is constructed of light weight material such as aluminum and may be hand held during operation.
