Our ABS sluices use a drop riffle design for faster cleaning action and provide higher production levels so you can process more gold bearing material in a day. More material run equals more gold in your sluice box!
Drop Riffle Stream Sluice measures: 10"x 39"
9 3/4" across the top and 9 1/4" across the bottom
This stream sluice box is made from ABS plastic to take years of abuse from your prospecting activities. Light weight, easy to use, even easier to clean out. This sluice box utilizes the same drop riffle technology as our famous bucket sluice concentrator and our larger high bankers.
These drop riffles work just like the natural cracks in the bed rock.
All material must fall into the riffles because of gravity. The lighter waste material quickly flushes away and out of the box leaving the heavier material (gold) behind.
Drop riffle sluice boxes are intended to be used a bit differently than the old style Hungarian riffle sluices. When running a drop riffle sluice box the best practice is to run the box as flat as possible. Just set an angle that never allows the sand to just sit on the slick plates between the riffles. The flatter you run the sluice box the better the recovery rate on fine gold will be.
Water flow on drop riffle sluice boxes needs to be a bit higher than the old style boxes due to this flatter angle. Watch the sand in the riffles... when you have the proper water flow, you will see the sand dancing around within the riffles .Do not try to adjust the box to run the riffles completely clean! The heavy material within the riffles works much like jig shot, which allows the gold and heavies to fall through the suspended material and allows the lighter material to just float right past.
