    Gold panning is mainly a manual gold separation technique from other materials. Large, shallow pans are filled with gold-containing sand and gravel. The pan is submerged and shaken in water, sorting the gravel gold and other material. It quickly settles down to the bottom of the pan as gold is much denser than rock.

  • Mineral Processing Things Gold Pertol Rock

    It has long been a very common practice for prospecting and small-scale mining to use a sluice box to extract gold from placer deposits. Essentially, a sluice box is a man-made channel with riffles at the bottom. In order to allow gold to drop out of suspension, the riffles are designed to create dead zones.

  • Gold Mining Process Development Denver Mineral Engineers

    In order to channel water flow, the box is placed in the stream. At the top of the box is placed gold-bearing material. The material is transported by the current through the volt where behind the riffles settles gold and other dense material. Less dense material flows like tailings out of the box.

  • Gold Processing Extraction Smelting Plant Design

    While this method has been largely replaced by modern methods, small-scale miners use suction dredges to make some dredging. Small machines that float on the water are typically operated by one or two people. A suction dredge consists of a pontoon-supported sluice box attached to a suction hose controlled by an underwater miner.

    Also called a cradle, it uses riffles to trap gold similarly to the sluice box in a high-walled box. A rocker box uses less water than a sluice box and is suitable for areas with limited water. A rocking motion provides the movement of water needed to separate gold in placer material from gravity.
