Sluice boxes have been used by gold prospectors for years. The bottom of a sluice box is covered with so-called riffles. Water flows through these riffles, and any heavy material, including gold, falls to the bottom of the box while the water and any lighter materials, including sand, is washed away.
Most recovery systems on suction dredges use fixed riffles to trap gold out of lighter streambed materials as they are washed through a sluice box by a flow of water. Riffles are baffle-like obstructions, fixed in place along the bottom of the sluice box.
