  • Gold Well Vortex Drop Riffle Sluice Box

    Since the majority of the available gold in the world is micro fine and ultrafine gold in the 30 micron (.0011 inch) range, you want a sluice that can collect that gold and keep it from running out the end. The Gold Well Vortex Drop Riffle Sluice works by creating a gentle, vertically oriented vortex. This vortex keeps material in the spiral ...

  • Riffles and Sluice Boxes - Gold Fever Prospecting

    Most will have riffles, spaced evenly along the length of the sluice, usually every few inches, perpendicular to the length of the sluice. Riffles cause small barriers to the water flow which creates eddies in the water, giving the heavier material (black sand and gold) a chance to drop to the bottom, behind the riffles. The "upstream" end of ...

  • » Setting the Proper Water Velocity Through a Sluice Box

    Sluice boxes process material best when receiving it from a steady feed. Too much material dumped at once into a sluice box has a tendency to overload the riffles and choke off the concentrating-action behind the riffles. This will cause gold to wash right through the sluice box as if there were no riffles

    The other great advantage is with the riffle design.

Just like in a river there are a variety of riffle trap designs with some more effective at capturing the big ...

  • How to SIZE a Sluice Box - Mineral Processing Metallurgy

    This week I went and asked “how to SIZE a sluice box” to the crew on a large gold prospector forum and other sluice or gravity gold recovery ‘experts’ and gathered the list of emails and forum posts here below. As you will see, in summary, most can optimize or troubleshoot a sluice box but few or none can size a gold sluice box.

  • Gold Sluice Boxes for Prospecting - Water Powered

    Riffles are purposeful obstructions which slow the movement of gold in the sluice so it can be trapped in miner's moss, carpeting, or rubber matting in the bottom of the sluice.
