Abstract
A gold dry washer comprised of a stand assembly and a trough assembly. The trough assembly is angled from an upper end with a hopper for raw soil to a lower end where denser gold is collected. Along the declining path of the trough are a series of graduating apertures that successively isolate the denser materials in the soil and allow waste to fall overboard. The stand assembly includes a motor or other gentle agitation means to encourage the dry soil to move with the aid of gravity towards the lower end of the trough where the heavier gold may be collected.
