Keene Gold Suction Dredges

The suction dredge is the best method for the small miner to recover gold from underwater deposits. Dredging is a relatively inexpensive method of mining for small one or two man mining operations, and can provide reasonable returns for the hard-working miner. Keene Engineering is the world's largest manufacturer of portable mining equipment and has long been the industry standard for suction dredges.

The U.S. Environmental Protection Agency requires a free permit for all small suction dredges operating in the State of Alaska. All dredges with a nozzle opening of 6" or less are defined as "small dredges". Note that this is not the hose size that the manufacturers use to identify their dredge models, but the measured nozzle opening. The EPA allows the nozzle opening to be up to 2" smaller than the hose inside diameter. All dredges used in Alaska with a 6" or smaller nozzle opening require the EPA Small Dredge Permit found on our Suction Dredging Regulations page.

2 1/2" Keene Gold Dredge (Honda)
Keene 2.5" Gold Suction Dredge
This 2.5" dredge is equipped with all the latest innovations in dredge design similar to the larger dredges. This is an extremely versatile dredge that can be used as a standard floating dredge with an optional air compressor for deeper dredging, or bank mounted for shallow water applications. Note that floats shown in yellow in picture are now granite gray.

 

Features for the 2.5" Dredges
The flotation is extremely light and compact and can be assembled or dismantled in a matter of a minutes. The floats have built in storage indentures providing a place for your tools, mask, rock pick etc. The floats have stringers, or "runner bottoms" for fast water and rock laden bottoms. Model 2503PJ weighs only 95 lbs.
The dredge is equipped with Keene's powerful P100 pump with oversized pressure hose making it a more powerful dredge than ever before. Experience greater suction power with either the power jet or suction nozzle.
The sluice box has rolled top edges, tapered sluice design, longer classifier screen and improved riffle design for superior recovery. Equipped with ribbed black rubber matting, for quick identification of values, under a longer classifier screen. This 2.5 inch sluice box surpasses all previous designs for both fine gold recovery and ease of use.
The Marlex Jet flare is built with a longer straight section and flare making it possible to use a shorter power jet to reduce weight. The jet flare design also improves fine gold recovery and increases suction power. The jet flare also makes the dredge easier to set up in shallow water conditions. The sluice box can also be set independently on a flat area next to the water.
The sluice box design is built to accommodate a power sluice hopper (see below).

Keene 5" Suction Dredges - Keene's 5" suction dredges are built on the same frame and float assembly as the 6" dredges, use the same motors and pumps, and even the same sluice box. basically you are getting a 6" dredge necked down to a 5" via a smaller flare, jet, and hose assembly. Since the weight, fuel consumption, and price differences are minimal we highly recommend you purchase a 6" instead of a 5" dredge. There are no permits required for 6" dredges in Alaska that are not the same as those required for a 6" dredge so there is no permit advantage. Basically, if you are going to spend the money, haul the weight, and burn the gas, you might as well be moving more yards with a 6" dredge instead of limiting your volume with a 5" dredge. But if you need one, we do stock a couple.
