Alluvial Pacific dredges can be used for gemstones, diamonds and finest gold recovery.
Ordinary riffles accumulate heavy black sand, most of content magnetic minerals have specific gravity about 4.9-5.2g/cm3, which pushes out valuable gemstones( SG of ruby and saphires -4.0g/cm3, SG of diamonds- 3.5g/cm3). In all our dredges and sluices we use NbFeB Permannent Strong magnetic field ( B=1.5 Tesla), which removes all stong and week magnetic minerals. This also improves finest gold recovery due to fact 80% of concentrate is magnetic and removed from riffles.
1. 4-inch (50mm) stainless steel nozzle
2. Stainless steel riffles
3. Strong Magnetic separation system for recovery diamond and gemstones
4. Heavy duty hard impact plastic tube with riffles and NOMAD matting for fine gold recovery
5. DC 33Volts/25A, 700 L/min two heavy-duty pump with fuse protection

FULL PRODUCT DESCRIPTION
• Very Handy Suction Dredge can be used for prospecting and selective mining for remote accessible areas.
• Comes with stabilizer buoyancy tank
• Dredge has advantage of low weight (12 kg compared to 4-inch floating dredge weight 290 kg)
• Not noisy at all
• Runs completely under water.
• Can be used with electric Hookah compressor for deep diving operations
• Not producing any dangerous exhaust fumes compared to fuel motor powered dredges
• Easy switch on /off operation.
• Best gold mining tool for beginners and professional miners
• Stainless steel suction nozzle last much longer compared to mild steel nozzles
• Easy cleaning process with just tip over in plastic container makes dredge very efficient for quick hole test
• Know-how special jet and box design increase suction and volume of running water.
• Can operate from portable Solar panel or portable in-stream mini hydro turbine
• Sliding extension rubber hose makes ease cleaning of narrow deep crevices and sure get all gold
• Dredge can be use also for treasure hunting in sea salt water application (comes with mesh version end box)
We recommend to empty dredge every 1-2 hours, it reduces fine gold loss and occasional tilts loses.
During operation we recommend frequently using the on /off switch. It will last battery running time and increase pump efficiency by cooling off the electric motor.
Dredge has improved riffles design with a woven wire matting system separating all fractions gold. Because pulp runs in close box, there are no air bubbles surface tension fine gold loss, which exist in open sluice box.
For quick cleaning process just tip over the tube in container with water
