The Keene A52S Super Sluice Box is the first sluice that allows you to dump unclassified material through the box at much higher volumes than ever thought possible while still retaining fine gold! Not only does this sluice a eat material like no other, it is the easiest and fastest sluice to set up in the world. ... This allows the riffles to ...
Adequate Riffles. The riffles of your sluice box are the primary tool responsible for the recovery of gold, from larger nuggets to smaller particles. However, not all of them are adequate to prospect for fine gold. Hungarian riffles. Also called "lazy L" riffles, these baffles are gently curved[5] and usually made of steel.
Various types of riffles, such as Hungarian, Vortex, or expanded metal, can be used. Additionally, ensure the sluice box has the appropriate slope or angle for efficient gold recovery. ... Test your hand-fed sluice box in a controlled environment, making any necessary adjustments to optimize its performance. ...
Hungarian riffles. The Hungarian riffles aid in the breaking-up process, as materials pass over them and down the box, but they serve another important function. Every riffle …
So miners started steadily making Hungarian Riffles in the mid 1800's, perpendicular to the flow, custom metal bars meant to allow for the gold to find a low pressure zone in the flow behind the riffle & collect. This worked great for large & medium gold, but was hit & miss for that sneaky fine Au.
As the box stands now, it has 4 standard riffles with large expanded metal behind them ( the type of expanded that you may walk on on a catwalk), I'm considering …
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 …
This gives aluminum quite an advantage and it is certainly preferred in the construction of the homemade sluice. The trough of the hand fed sluice, whether made of aluminum or wood, is usually roughly the same size - in the range of about 8 to 12 inches wide, so on a sheet you'd need the width plus an extra 4 inches on each side.
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 basic hand fed sluice box does not need to be very long, 3 to 5 feet is generally adequate. Many people design elaborate sluices that are way longer than necessary.
That's why you don't want a bunch of OBSTACLES… i.e. riffles or aggressive matting further down your sluice. How often should I clean out my mats? Normally we don't worry about this much. Example… If we're running a highbanker we only clean out twice a day. But, with a stream sluice you often have varying flows and crazy turbulence.
Most sluice boxes use riffles or obstructions blocking free flow of gravel and sand from being washed out of the sluice box. These restrictions form low pressure pockets behind which gold will accumulate. Gold is 19 times heavier than water and approximately 16.5 times heavier than quartz, so...
With the riffles closer together you get the water bouncing back off the next riffle down to really create that churning, vibrating, sorting action betwwen the riffles. Not so much when the riffles are spaced firther apart With a stream sluice & classification you can have a gentler flow of water & you are more in control of what is happening.
The sluice box often is lined with "miners moss" a material that holds the gold in the separation process for improved recovery. The sluice is lined with a set of removable …
15 degrees from the vertical angled towards the head of the sluice is the ideal angle for Clarkson riffles. If you are running standard Hungarian riffles, there isn't …
These Sluice Boxes have been designed to find the maximum Gold, including The Fine Flour Gold. ... your materials are lifted, the fine Gold hits that flow of water and out they go. You never knew you caught them. Drop Riffles use gravity to allow the Gold to drop into the Riffles naturally. Remember a Gallon of water weighs 8.5 Lbs. and a ...

15 degrees from the vertical angled towards the head of the sluice is the ideal angle for Clarkson riffles. If you are running standard Hungarian riffles, there isn't a set rule, although, if their angle is to low, they become nothing more than a speed hump. Better keeping the angle between 15 and 20 degrees off the vertical sloped downstream.
First set was at 18 degree from vertical with a .25" top lip that had an 18 degree kick up from horizontal. The riffle had no bottom lip so I guess you could call it a …
non bearing values and larger aggregate are returned back into the water .The riffles, or gold traps in the sluice box are best described as "Hungarian Riffles". This type of riffle has proven to be the most efficient gold recovery system. As material flows over the riffles, a vortex, or eddy current is formed between each riffle opening.

Nearly all portable dredge sluices have Hungarian type riffles, and I wanted my homemade sluice to have them as well.

All this being said, the typical size for a hand-fed sluice and high-banker is 10″ wide. Classifying smaller than 1/4″ slows the operation down substantially (yes, there are a few work-around). Very few folks can effectively use sluices larger than 12″ in hand fed operations. Water requirements are about 28-30 gpm with more being better.

On the other hand, expanded metal riffles leave a minimum amount of concentrate to be panned at the end of a sample run and this time-saving feature makes them easy to clean up. Many engineers compromise by equipping the upper 2 or 3 feet of a sampling sluice with Hungarian-type riffles and the remainder with expanded metal lath.
Every prospector has his or her own opinion as to the best material to have under the riffles of your sluice box— Deep V Matting, Carpet, or Miners Moss. There is no single right answer just like there is no single right answer for which brand or size of sluice to use— the one you take to a beach for fine gold recovery is probably not the same …
These rely entirely on inducing eddies in order to generate pockets for gold deposition. Larger riffles create deeper, more turbulent pockets and vice versa. The sluice run is therefore often composed of multiple sections: Angled riffles (angle iron or Hungarian style) generating deeper pockets …
The riffles create gold traps which direct the gold into the carpet which captures and holds the gold. Many types of riffle designs exist, the most common being an inverted "L" design referred to as "hungarian riffles". Expanded metal screening of various types are also used in many sluice boxes as a riffle or in conjunction with other riffle ...
It usually sits under the classifier screen that is placed at the head of the sluice box. Keene Miracle mat has Hungarian style riffles built right in. Spot ultra fine gold easily and quickly with a quick glance at the Miracle Mat. Riffle info: approx. depth: large riffles are 5.15mm tall, 32mm between riffles.
