  • Non-motorized gold mining apparatus - Rothery, Brian

    Gold mining apparatuses typically use motors to create suction pressure for sucking the medium rich in particulate, making them cumbersome and expensive. It is therefore an object of the present invention to provide a non-motorized gold mining apparatus that is significantly lighter, smaller and less expensive to operate. A further object is to provide a non-motorized gold mining apparatus,

  • Non-motorized gold mining apparatus - ROTHERY BRIAN

    Non-motorized gold mining apparatus . United States Patent 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,

  • WO2007108707A1 - Mining apparatus and method - Google

    A gold recovery apparatus having at least one flow path through which a slurry can be passed. At least a portion of the lower part of the interior of each flow path has a non-smooth surface. Each flow path is configured to promote a substantially non-turbulent or laminar flow in any slurry passing through it except adjacent to the non-smooth surface.

  • Placer mining sluice box apparatus and method - ROSS, LORNE M

    In an attempt to deal with the difficulty of recovering the fine gold particles, placer mining apparatus has been designed in an attempt to segregate the coarser aggregate material and separately process the finer aggregate material, so that the fine gold particles can be separated and not subsequently mobilized and lost. An example of such apparatus is shown in U.S. Pat. No. 2,174,925, issued,
