Suction Gold Dredge Basics
A suction gold dredge is basically an underwater vacuum cleaner. Material is transported from underwater to the surface and run through a sluice box to capture the gold. A sluice box works because gold is 15 times heavier than sand and gravel and so is easily trapped by the riffles and carpet in the sluice box.
