The Gold Coast is undoubtedly one of Australia''s unique and most liveable cities, with more than 300 sunny days per year. It can be even called as ''The City of Canals'', since extensive navigable waterways are stretching around the city. There is a significant and rapid increase that can be observed in recreational boating activity on these waterways and the maintenance of these channels

A suction gold dredge is basically an underwater vacuum cleaner. Material is transported from underwater to the surface and run through a sluice box to capture the gold. A sluice box works because gold is 15 times heavier than sand and gravel and so is easily trapped by the riffles and carpet in the sluice box. Dredges almost always need to be mounted on a set of floats. This is because a

Different Sized Dredges . Suction dredges are sized based on the diameter of their suction hose. They can be anywhere from " up to 10" or larger on custom commercial applications. Most popular dredges are around 4" to 6", which are a good size for a 1 or 2man dredging operation. Although the larger dredges can recover considerably more gold, larger sizes get

A gold mining dredge has a totally different design and purpose. A gold mining dredge utilizes a device called an "eductor" in conjunction with an inexpensive water pump. This system is designed to pump a lot of water with low slurry content a relatively short distance, usually into a nearby sluice, and is normally deployed by a scuba diver. The Mini dredge does the opposite.

The principle is completely different from any jet on the market. The water from the 360° jet (same diameter as the dredse) is applied on the outer edges of the column of water. There are many advantages to this design. The cavitation is almost zero; the outside surface tension is broken by the force of the surrounding jet. The jamming appears to be less because the force of the water is

Hydraulic mining is a form of mining that uses highpressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting watersediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft

Suction dredges utilize a high pressure gasoline powered water pump to suck up water, gravel and gold and inject this material into a sluice through a header box. The header box dampens the rush of water and gravel so that it flows evenly into the sluice. The sluice box then expels the

One major problem associated with all gold dredges over the years has been the far too frequent rock jams in the dredge hose, particularly at the power jet. On conventional dredge designs, the steel power jet slips inside the hose, creating a restriction and many plugs in the process.
