Why Are Dredge Sluices So Short? - Sluicing, Highbanking ...
The area we are dredging has pretty fine gold, with small nuggets to about 1/4" but that is about it (so far). So we have been researching the heck out of fine gold recovery and I think we will catch more with a longer sluice or series of sluices.

» 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 ...

How Does a Gold Dredge Work - Mineral Processing & Metallurgy
The available space on a dredge is so small that long sluices are out of the question, and it is therefore necessary to disintegrate the gravel thoroughly in trommels or on shaking screens, and to make the gold-saving tables as wide as possible, so as to reduce the speed and depth of the stream of gravel running over them, especially where fine ...

Gold Sluice Box Design
On one dredge, gold recovery was 90% for 12-hour gold cleanups and increased to 94% when sluices were cleaned every 2 hours (Zamyatin and others, 1975). For cleanup, clear water is run through the sluice until the riffles are clear of gravel.

» Double-screen Classification System in Dredging
While effective, the problem with the side-by-side sluices is that the side sluice(s) normally have to be placed on top of the dredge's pontoons. Therefore, in order for gravity to make everything work right, the initial feed to the dredge has to be lifted higher out of the water.

As viewers witnessed in a previous season, the dredge sank twice in a six-week span. In the second incident, fine sand plugged up the sluices and spilled onto the deck beneath.
