Using a dredge, an (experienced) operator is able to process a much larger volume of streambed material than with any other small-scale hand-mining apparatus. Most of the gold-bearing river-bottom streambed material is sucked up as quickly as the operator is able to feed it into the suction nozzle.Rocks that are too large to pass through the …

A suction dredge is basically an underwater vacuum cleaner that sucks (hopefully) gold-bearing gravel up and runs it through a sluicebox. In more technical terms, suction is created by a motor-driven centrifugal pump moving high pressure water into a jet system, creating a low pressure area that creates suction at the nozzle via the venturi …

When the tip of the suction hose is taken out of the water during operation air will to enter the suction system and cause the suction power to cease temporarily, until submerged again. The suction will commence as soon as the air is passed through the system. It is important to ensure that no air leaks occur in the suction system.
