The non-motorized sluices below are made by Jobe, Tee-Dee, Le Trap, RDH Prospecting, Gold Buddy and are all considered hand sluices. A steeper grade may result in all but the coarsest gold being carried away by the force of the water. At least start here, and adjust as needed. Since gold is heavy, it will stay in the bottom of the sluice, trapped in the miner's moss.Ī good rule of thumb is to set your sluice at a grade of one inch per foot of drop. The idea is to position a sluice box in a running stream so that the water does the work- separating the dirt and rocks away from the gold. Nineteenth century gold miners used wooden sluices that were at least 12 feet long, but modern gold prospectors primarily use sluice boxes made of plastic or metal which are typically 24, 36 or 48 inches long and 6 to 10 inches wide. 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.

Sluicing is a method of separating and recovering gold from the placer gravel by the use of running water.

Sluices are long, narrow 'boxes' that water passes through when put in a creek or stream.
