What’s the best angle for a sluice box?
between 5 – 7 degrees
When setting up a sluice the proper angle must be observed. It’s usually between 5 – 7 degrees of slope and should allow most round rocks and pebbles to pass through easily. You don’t want the material zipping through but rather kind of tumbling through slowly.
How far apart should riffles be in a sluice box?
For the indicated speeds and the riffle heights the necessary spacing should not be more than 20 cm. The peak recovery was obtained at a riffle height of 1.0 cm but dropped after 20.0 cm spacing.
What is a drop riffle?

How does a sleuth box work?
Sluice boxes work by essentially creating a straight, consistent channel, with regularly spaced slow spots created by riffles. Each riffle creates an eddy, a backflow of water that allows the gold to settle out. Material is placed at the top of the box and carried in suspension down the channel.
What is a gold sluice box?
Sluices are long, narrow “boxes” that water passes through when put in a creek or stream. 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.
