FOR SALE: Jobe Highbanker Dredge (Sluice Only Used twice) (Motor & Dredge Hose Never Used) Location: San Bernardino, California (Send PM if interested $650.00 For Everything) COST: $839.00 About Power Sluice / Highbankers: A power sluice, sometimes called a highbanker or hibanker, is a piece of gold prospecting equipment that uses a pump to force water through a sluice box to mimic the natural flow of a river. Sometimes a hopper box with spray bars and a classifier sieve (or grizzly screen) is employed. Gold bearing gravel is shoveled into the hopper box and washed over the classifier screen to remove waste gravel and pieces of rock that are too large to go through the sluice. The water pump is gas powered. If the sluice is designed to catch and recirculate the water it is called a recirculating power sluice, or recirculating highbanker. These are usually powered by 12 volt electric batteries. Highbanker Benefits: Rather than haul material to the water, you can bring a lightweight, efficient power sluice directly to the source. The power sluice / highbanker can work remote placer gold deposits hundreds of feet away from the water source. In the case of recirculating sluices they can be operated in arid desert areas with very little water. The typical hopper design washes clay and debris with a high pressure washing spray bar and all washed material becomes classified to less than 1/2 inch for improved fine gold recovery. The spray bar is also equipped with a water valve for ease of controlling the flow in the sluice. The sluice box itself is constructed like a normal stream sluice except it is equipped with an adjustable independent leg support system that enables the power sluice to be assembled on any type of terrain in a matter of minutes. Combination Dredge / Power Sluice Option: If a power sluice uses a high pressure gasoline engine it is relatively easy to adapt it so that it can also function as a small dredge. Combining a power sluice and portable dredge creates a very efficient gold recovery system that can be used in most any situation. Typically these dredges have 1 1/2 to 3 inch suction nozzles and are designed to work in shallow water without the need of underwater diving equipment or air compressors (hookas). We call this long arm dredging. The sluice box may also be modified for dredging with deeper Hungarian style riffles to accommodate the increased water flow and velocity. Other modifications can include adding miners moss or special carpets and ribbed rubber matting to improve fine gold recovery.
