  • Non-motorized gold mining apparatus
    Patent number: 8240775
    Abstract: A non-motorized apparatus for collecting particulate materials, including gold, in stream placer deposits, comprising a first tubular member, a second tubular member, a riffle tray with perforated ridges, a skirt for enveloping the tubular members and directing stream flow, and a fibrous matting held entirely inside the second tubular member. The second tubular member is connected to one end of the first tubular member in a way that a high velocity stream flowing into the first tubular member creates suction pressure in the second tubular member. The particulate matter settles in grooves formed by the ridges in the riffle tray and passes through perforations to become trapped in the fibrous matting as the stream is drawn into the second tubular member.
