May 05, 2017For serious placer mining operations, the suction dredge is the best tool to process large amounts of material from the riverbed as quickly as possible. Dredges have a learning curve to operate efficiently, but one you figure out how to use them properly you will find that they are by far the best way to get the most gold in the least amount of time.
