A sluice is generally defined as an artificial channel through which controlled amounts of water flow. This even comes with a pick and hook set to get into those hard-to-reach spots. As water carries gold-laden sediment through the box, small obstructions called riffles block the free flow of material.

The hopper is huge for simple feeding at 40 X 27 and contains 143 rivets. Even so, you still set them all up the same. As for the gold dust, the added weight will still cause them to settle more in the sediment in a creek or river so a tool can find it. In either case, the materials pass through a sluice, where gold is collected behind riffles. Sluice boxes can be made out of wood, aluminum, plastic or steel. It has a good-sized platform too so you can better separate classified material. Boulders from the first cut should be stacked outside the pit, on barren ground if possible. Inside the boxes, various kinds of riffles may be employed, depending upon the availability of material and personal preference.

Reduction in the amount of material to be treated by first running it through a trommel to wash and screen out the coarse size is another effective way to lower the water requirements. Turning to the sluice box, a primary feature is its interlocking design. As heavy sands and gravel build up deposits between the riffles in the sluice, it may be necessary to stir these up to prevent packing and the consequent override of gold particles. Areas with the most erosion generally have the greatest concentration of gold values. All material of a size that will run through the sluice is shoveled in, and the oversize material is thrown to one side. Water is directed through the sluice box, and as it flows, the heavier materials such as gold are trapped in the riffles (ridges) while the lighter materials are washed away. [citation needed] The result is a concentrate which requires additional processing. Additionally, the box is built with convenience in mind thanks to the Mini Max folding leg system. The most important depths in designing of sluice gates are:[1], Flow under sluice gates could be described using energymomentum concept by assuming that energy losses are negligible.
