Sluicing - How to set the correct angle on your sluice box

When the box has finished running the gravel down onto the riffle area of the box, the space fills between the riffles, you can start to look for the last of the gravels to leave the front of the box. Now, if the box is running too slow, you will not see most of the carpet clear behind the first riffle for something over 45 seconds of time. If the box is running too fast then you will see most of

Sluicing - How to set the correct angle on your sluice box

I can't tell you how many times someone has asked, "What angle do I set up my sluice box". The worst part is, there is no stock answer. Every river and stream is different. The average specific gravity of the sand can vary so much, there is not one setting to go by, water flow may be faster in one spot than another. I have moved up river 50 ft and had to change the angle.

Riffles and Sluice Boxes - How do they work?

The slope or angle of the sluice can be adjusted, by arranging rocks under the sluice. Also the flow of water can be adjusted by placing a large rock in front of the intake end of the sluice, to divert some of the water around the box. You have to adjust these variables several times until you get the material moving through the box at the correct speed leaving just the black sand in

The Size of Riffles - goldgold

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 over top. When the correct water-flow is directed over a riffle, the back pressure keeps the area just behind the riffle in a state of continuous fluid suspension.

Sluice Boxes and Highbankers - BC Placer

In a "Mat/Screen/Riffles" sluice box, when the angle and water flow are just right, (most) gold will be retained behind the riffles, while most of the regular sand and some of the black sand (and probably some of the fine gold) are flushed out. Clay and Fine Gold Breaking up any clay is very important. If little balls of clay can roll down the sluice box, they can pickup and "steal" gold

Unfortunately this type of dual-mode sluice is a compromise that sacrifices recovery efficiency somewhat but it saves most of us from having to carry two different boxes, or multi-level boxes into the field. For fine gold recovery the use of riffles can actually be a negative design

Vertical Angle Iron Riffles. The vertical types of Angle Iron (or aluminum angle sections) do not seem to perform much better than the sloped flat bar riffles, even though the upper horizontal lip supposedly aids in vortex creation. The horizontal lip helps to a point, but not nearly as much as ecpected. Basically the lip simply increases the length of the vortex in comparison to a sloped
