Doing the separation is a matter of adjusting angle and water flow to separate the black sand from the much denser gold. Another type of sluice for concentrates is made from a piece of corrugated plastic drain pipe 4 to 6 inches across and 6 to 8 feet long. The pipe is cut in half length-wise and one half is screwed to a plank open side up.
