The RL-3045 Portable Sluice Box is a lightweight, foldable gravity separation tool for small-scale alluvial gold mining, combining classic riffle technology with modern high-efficiency matting systems. Engineered with high-grade aluminum alloy (resistant to corrosion and impact), it weighs just 85 kg and collapses into a 90cm x 41cm x 35cm carrying case—easily transportable by backpack, ATV, or helicopter to remote prospecting sites. The dual-layer riffled rubber matting (300-mesh bottom layer for fines, 10mm riffles for nuggets) and adjustable water flow control ensure 95%+ recovery of gold particles as small as 0.05 mm, even in low-water conditions.

Foldable Design: Heavy-duty stainless steel hinges allow collapse into a compact carrying case, with assembly in 10 minutes using no tools—critical for backcountry prospecting.
Adjustable Slope Mechanism: Manual telescoping legs let operators set 5-15° angles, optimizing water velocity (1-2 m/s) for different sediment types (sand vs. gravel).
High Recovery Matting: 300-mesh rubber bottom layer traps fine gold, while 10mm riffles create eddies to capture larger particles, eliminating the need for multiple passes.
Low Maintenance: Matting is removable for easy cleaning, with replaceable sections extending service life—no specialized tools required for upkeep.
Prospecting Expeditions: Portable enough for backcountry riverbanks and mountain creeks inaccessible to heavy equipment.
Small-Scale Mining: Processes hand-dug sediments or tailings from larger dredging operations, maximizing gold recovery from overlooked material.
Emergency Recovery: Rapidly deployable in disaster zones with damaged infrastructure, providing a low-tech means of resource extraction for local communities.
Q: Can it be used with a pump?
A: Yes, it’s fully compatible with 3-inch dredge pumps (30-50 PSI) for areas with insufficient natural water flow.
Q: What’s the recommended water pressure?
A: 30-50 PSI creates optimal turbulence—lower pressure for fine gold, higher pressure for gravel-rich sediments.
Q: How to clean the matting?
A: Hose down after each use to remove loose sediment; deep clean with a soft brush every 20 hours of operation to prevent matting clogging.
