    Gold Jig & Mineral Processing Jigs. The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because of ...

  • Jigging | industrial process | Britannica

    In mineral processing: Gravity separation. In the process called jigging, a water stream is pulsed, or moved by pistons upward and downward, through the material bed. Under the influence of this oscillating motion, the bed is separated into layers of different densities, the heaviest concentrate forming the lowest layer and the lightest product the…

  • Mineral jig - Wikipedia

    Mineral jigs or gravity concentrators were designed to allow for separation of materials with different densities. This process is accomplished by flowing a stream of liquid-suspended material over a screen and subjecting the screen to a vertical hydraulic pulsation. This pulsation momentarily expands or dilates the screen bed and allows the heavier materials to work toward the bottom. Heavier ...

  • Processing Methods | Diamcor Mining Inc.

    Processing Methods. Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are Rotary Pan plants and Dense Media Separation (DMS). Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery. These systems are based on the property of diamonds having a much higher ...
