The simple sluice box is not used much in the desert since these are placed in a stream with running water.

The type, size, shape, angle and spacing ...

The steeper the angle the less water volume needed to acquire the correct water speed needed for proper operation. The average angle of operation is 6 to 8 degrees with a water depth of approximately. 3/8 of an inch above the surface of the Vortex plate. The average water volume required for the widths of sluices are as follows:

A ratio of 2.5:1 is perhaps 'perfect'. In other words, if you're feeding the sluice 1/4" gravels the maximum riffle height should be 3/4" or less as an example. The 'perfect' height for 1/4" gravels would be 5/8" but this riffle height would be a custom fabrication. Almost all 'mass-produced' riffles are far too high for ...

A sluice box is one of the most useful devices to process large quantities of streambed material and the preferred one by small-scale miners and recreational prospectors. Sluice boxes are affordable and allow gold hunters to streamline the process of examining the placer, making it up to 200 times faster than just using a gold pan.
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.

A sluice box should be set with a 4-8 degree angle. Another rule of thumb is that the sluice should be angled to drop roughly 2 inches per foot of length. The exact angle depends on the size and weight of the material, the riffle design, and the speed of the current. As you see, there is not a universally applicable answer as to what angle is ...
