ABSTRACT:
A portable gold mining dredge for use in collecting potentially gold containing aggregate from streambeds for subsequent classification and separation. The dredge has a receptacle, comprised of a drum with a water-tight lid, for receiving the aqueous dredged aggregate. The receptacle is of a size suitable for carrying. A self-priming pump having an inlet port and an outlet port is attached to the receptacle. A dip tube extends into the receptacle, the outer end of the dip tube being connected to the inlet port of the pump by a conduit. A suction tube communicates with the interior of the receptacle. Hoses are connected to the inlet of the suction tube and to the outlet port of the pump. During operation the suction hose is used to suck up aqueous aggregate from a streambed and the discharge hose is used to wash aggregate from cracks and crevices in rocks.
