Recovering fine gold in large quantities is an art form. Most flour gold passes right out of your sluice box.
I've designed a sluice box that captures almost all this gold dust. There are some main differences from early sluices, starting with the lack of riffles. This high volume fine gold sluice box uses a continuous capture system. The entire bottom is a recovery system. The key is to vary the pressure, high / low / high repeatedly. This pulses the fine gold out of the flow. Causing the yellow metal to drop out in bands through out the bottom of the sluice. In addition, There is a special brush set up that combs the gold out of the sluices flow.
Finally magnets catch black sand, which in turn recovers super small gold particles. Easy.
This fine gold sluice is designed just for the smallest gold. It will capture gold pieces up to 1/8 ounce.
Setting the flow rate is very easy. There are 2 movable doors that open to set the water rate through the box. A real positive is that this sluice is almost oops proof
The reason I built this box is because of my frustration on losing A LOT of fine gold. Whether its gold dust or flour gold, this sluice will recover it. Since there's gold right at our feet, it only makes sense to get that gold. There are beaches and deserts loaded with this easy fine material, not to mention the streams and rivers.
With the price of gold at record highs, this hobby pays you to have fun and enjoy nature at the same time. Too bad all recreational activities weren't like that.
