A sluice box operated for extended periods with no new material being fed to it has an increased chance of losing some of its fine gold values.

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.

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. Second, the riffles are spaced a couple of inches apart, and act as a series of small dams, stopping the creep of the heavy material down the sluice.
