Gold Sluice Boxes for Prospecting - Water Powered - Gold ...

Sluicing is a method of separating and recovering gold from the placer gravel by the use of running water. Gold is caught or trapped by riffles. 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.
