A Recirculating Sluice Box for Gold Prospecting

I tested the sluice using two different kinds of paydirt. First I used some crushed gold ore from a working hard-rock gold mine, just to see how well the sluice would catch gold.

Riffles and Sluice Boxes

The reason that riffles work is two fold. First, there is an eddy created behind each riffle, causing a temporary lull in the water flow. The material that is flowing is in a liquid state. This causes the heavies to be at the very bottom of the flow. As the flow passes over a riffle, the heavies will fall to the bottom behind a riffle.

What Is a Sluice Box Used For? – Prospectingplanet

A sluice box works by using the fact that gold is much denser than other materials on the streambed. As the collected material flows through the sluice box, the gold will rapidly fall through the gaps and ends up being trapped on the rubber mat or along the "riffles." The other materials will just run through the device and back in the stream.
