· From the earliest gold rushes to the present day, the sluice box has remained a staple tool for prospectors and placer miners. Despite advancements in engineering over the years, gold sluices have changed very little since they first became popular – after all, "if it ain''t broke, don''t fix it!" This is due in part to the solid design philosophy that gold sluices are based on. While

· This sluice design will work best on fine material such as fine gold and sand. The real target for this kind of sluice is beach sand, fine sand from streams, and glacial gold from classified material. Water flow and material classification are your only variables, but if you found this post I probably do not need to explain those things to you. I do suggest that you classify your material down

popular ''GoldBuddy'', a ''Grizzly'' brand mini highbanker, A G1 power sluice, A Proline 21/2" power sluice, a DK 11/2" power sluice and a new Keene 21/2" power sluice. All of this equipment was used in two different locations having very different dispositions and types of gold between March 12th and August 5th of 2009.

So as water flow is slowed down to catch finersized gold, it is generally necessary to use shorter riffles. Halfinch mesh screen is commonly used for primary classification in small and mediumsized sluicing operations, because the screen is large enough to allow classification to take place quickly, yet no materials greater than halfinch in size will get into the sluice.

attendant with some sluice designs, would require less water flow . but would be more sensitive to fluctuations in solid feed rate. However, lower solid feed rates, under suitable conditions, give marginally better recoveries. 3. Angle iron dredge riffles should be wed somewhere in the fine gold recovery area to recover gold particles much coarser than 20 mesh and smaller than the upper feed

For a given fluid flow: A wider sluicebox produces a thinner film of water and is thus more amenable to recovery of finer heavy minerals; and A narrower channel has a deeper flow and is more suited for recovering larger particles and transporting course gangue along the sluicebox. Sluiceboxes are always set at an inclination, the slope of which is again a balance between conflicting

· Truly an amazing design. Their Ultimate River Sluice does have a little of the O/U in the beginning in that the gold washes through the punch plate and goes into an underflow trap design. The "V" shaped shovel after the punch plate washes the unwanted overburden off to the sides. No need for classification for this design. There is also a set of holes before the "U" shaped UnderFlow traps that

They basic design is to lay the box in a stream or river, parallel to the flow of water. Gravel is shoveled into it at the head of the box, and the water moves the material over a series of riffles which help to separate out and capture the gold. When designing your sluice box, it would be a good idea to take a look at several commercially designed sluices to get an idea of basic design. A

The closed end of the Bank Robber Sluice can be cut out, creating the River Robber Sluice. The flared riffle design causes the water flow to slow as it passes through the sluice, resulting in optimum gold recovery.
