![]() ![]() ![]() I strongly advise you to study these issues for yourself as much as possible before deciding how to acquire accurate samples, and what to do for a production dredge if you decide to move forward with a mining program. There are numerous issues involved, each which must be carefully resolved to make it all work out right. If you want to learn more about how suction dredges work and how they find gold, check out our infographic below.Over the many years, my various partners and I have experimented a lot with secondary recovery systems to catch fine gold and gemstones that get sucked up the suction nozzle of a floating dredge. 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. ![]()
