How To Set The Right Sluice Box Angle (Tips Tricks) –

A sluice box should be set with a 4-8 degree angle. Another rule of thumb is that the sluice should be angled to drop roughly 2 inches per foot of length. The exact angle depends on the size and weight of the material, the riffle design, and the speed of the current. As you see, there is not a universally applicable answer as to what angle

How To Build and Operate Sluice Boxes

Good examples of this box type are the ‘DFS’ (Damn Fine Sluice) and Steve Gaber’s ‘Pop-and-Son Sluice’. On the other hand boxes designed to concentrate gold particles of 16-mesh and up in size must have riffles but don’t really have a need for the fine expanded metal mesh or even the Nomad matting though both are recommended.

Riffles and Sluice Boxes - How do they work?

Most will have riffles, spaced evenly along the length of the sluice, usually every few inches, perpendicular to the length of the sluice. Riffles cause small barriers to the water flow which creates eddies in the water, giving the heavier material (black sand and gold) a chance to drop to the bottom, behind the riffles.

2. Expanded metal riffles (such as the 1-10H) are superior to 1 1/4" dredge riffles for recovering placer gold between 20 and 100 mesh. 3. The orientation of expanded metal riffles is not important to gold recovery. 4. The practice of running "clean" or allowing the gravel feed to stop while water is flowing need not greatly affect recovery.

Proper Sluice Set Up - Gold Prospecting Mining Equipment

Place your sluice in the flow of a stream or river so that the water enters the flared end and flows through the sluice. If the current is strong you may need to lay some stones against the edge of the sluice to keep it from washing away. The sluice should be set at a downhill angle that allows the material to briskly flow through the sluice.

Best angle for a sluice box - CARIBOO GOLD MINERS

Nov 21, 2013  I run more of a beach box setup on fine flake flour gold. My box is 24" wide and runs rough top conveyor belt at 20gpm per foot of sluice width. I find best recovery is between 1/2 and 5/8th of an inch per foot. I see gold migrating a lot at 3/4 and I loose a fair bit at 1" per foot. This is on material screened to 6 mesh in my grizzly.

Sluice Box Cleanup - When to Remove Gold and Black Sands from Sluice Riffles

This can be attained a few different ways; you can resituate the sluice in an area that has slightly more flow, you can situate the sluice at a slightly steeper angle to increase the speed of water going over the riffles, or you can add a few rocks in front of the sluice to funnel more water into the box.

» Setting the Proper Water Velocity Through a Sluice Box

How much water velocity is directed over the box directly affects how much material will stay behind the riffles. When the correct amount of water force is being put through a sluice, its riffles will run about half full of material, and the material can be seen to be dancing and vibrating behind the riffles (concentrating) when the water is flowing.

Dec 02, 2009  If you increase the angle of your sluice box you will start to lose more of the fines. The problem is the packing of the black sand between the riffles that do not allow the fines to go to bottom and much of the fine gold will sail down the sluice box over the black sand and back into the river.

How to SIZE a Sluice Box

Optimum Slope of a sluice Slope of a sluice is generally in the range of 1.3 cm (1/2 in.) to 3.8 cm (1-1/2 in.) per 30.5 cm (1 ft), depending on the size rock in the feed. To move the larger rocks down the sluice requires a steeper slope or more water, both of which cause greater gold losses. Any number of types of collectors can be used in a sluice. Most common is the use of astroturf or ...

General : Sluices

The angle of the sluice box is everything. Too much and everything washes out. Too little and it plugs up constantly. Just right and gold and small gems are trapped in the riffles. NEVER set up the sluice so it is completely submerged! A couple of inches inside the box is plenty to do what you need to do.

How I built a recirculating sluice box for gold prospecting

So I hesitated for a while before taking the plunge and using steel. But I decided it was high time I learned how to weld anyway. So I bought some 1/2 x 1/2 angle stock and some 1/2 x 1/8 flat stock. My intent was to use the flat stock as rails on either side of the sluice and weld the angle stock between them to make riffles.
