How Gold Sluices Work - Manhattan Gold and Silver
Jun 07, 2017& 0183;& 32;As water carries gold-laden sediment through the box, small obstructions called riffles block the free flow of material. These tiny flow restrictions form low pressure pockets where the gold collects. Sluices are an effective tool for collecting gold, but they don’t work without water.

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. Riffles are purposeful obstructions which slow the movement of gold in the sluice so it can be trapped in miner's moss, carpeting, or rubber matting in the bottom of the sluice.

Sluicing - Wikipedia
In syntax, sluicing is a type of ellipsis that occurs in both direct and indirect interrogative clauses. The ellipsis is introduced by a wh-expression, whereby in most cases, everything except the wh-expression is elided from the clause.Sluicing has been studied in detail in early 21st century and it is therefore a relatively well understood type of ellipsis.

& 187; The Size of Riffles
Most recovery systems on suction dredges use fixed riffles to trap gold out of lighter streambed materials as they are washed through a sluice box by a flow of water. Riffles are baffle-like obstructions, fixed in place along the bottom of the sluice box. They are designed and positioned so that there is a back-pressure created that sucks water and material behind the riffles from the flow ...
