![]() In this guide, we look at what gold dredging is and how it differs from sediment removal dredging. Sediment removal has become increasingly important as we rely on waterways for shipping goods. Gold digging has an extensive history and is still practiced today. ![]() Since its resurgence, it’s become a popular way for small-scale miners to retrieve gold and other precious metals from public bodies of water. Dredging for gold using suction dredges can help the environment by removing excess sediment that can damage waterways. Sediment removal dredging focuses on removing built-up sediment and other obstacles from waterways to improve access. If you want to learn more about how suction dredges work and how they find gold, check out our infographic below.Dredging for gold is an old-fashioned mining method made new by modern technology. It also requires a large investment upfront, with the cost of equipment averaging several thousand dollars. The process involves hauling heavy equipment, lifting and moving stones too wide for the suction nozzle, fighting against the water’s current, and lots of swimming. While it may sound easy, suction dredging is much more difficult than vacuuming coins out of your couch cushions (or gold flakes out of your carpeting). In a way, the process is like a combination of the best parts of gold panning and gold dredging. ![]() These materials pass into a floating sluice, which filters and recovers the gold. It sucks up rocks, gravel, silt, and anything else at the bottom of a streambed using a gas-powered pump and suction hose. ![]() For the amateur prospector who wants to take their hobby to the next level but doesn’t want to work in a mine, upgrading to suction dredge can be a great way to find more gold while still enjoying the great outdoors.Ī suction dredge essentially works like a heavy-duty underwater vacuum cleaner. ![]()
