![]() These are usually powered by 12 volt electric batteries. If the sluice is designed to catch and recirculate the water it is called a recirculating power sluice, or recirculating highbanker. The water pump can be either electric or gas powered. 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. Sometimes a hopper box with spray bars and a classifier sieve (or grizzly screen) is employed. Power Sluices and Hibankers are available at the bottom of the page - scroll down.Ī 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.

Keep in mind that a pump delivers less water as your equipment location is moved uphill. If you prefer a high banker with high pressure spray bars, you are going to need a gas-powered pump. These pumps are submerged and make no noise. Generally, if you want to make a nice quiet power sluice or recirculator, a 12 volt electric pump is recommended. Large 12-volt electric pumps can deliver a lot of water flow but do not have the head pressure that a gasoline pump can deliver. 12-volt electric pumps are lighter and quieter than their gasoline-powered counterparts but require a battery. Gasoline or Electric Pump? There are advantages and disadvantages to everything and choosing between an electric or gas pump is puts you in the same dilemma. The sluice 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. The spray bar may be equipped with a water valve for ease of controlling the flow in the sluice. The typical hopper design washes clay and debris with a high pressure washing spray bar and all washed material becomes classified to less than a half inch for selective recovery. In the case of recirculating units, they can be operated in desert areas with very little water. The biggest benefit of having this piece of gold prospecting equipment is the ability to process gold-bearing gravels located a distance away from a water source- in other words, you get to bring the water to the gravel, not the gravel to the water! Rather than haul material to the water, you can bring a lightweight, efficient power sluice to the water source! The power sluice can work remote placer deposits hundreds of feet away from a river or stream. ![]() In general, a highbanker or power sluice is extremely efficient at trapping gold. ![]() If the unit is designed to catch and recirculate the water it is called a recirculating power sluice, or recirculating hibanker. Sometimes a hopper with spray bars is mounted on top, where the gravel is introduced into the sluice, to wash the gravel over a classifier screen to remove pieces of rock that are too large to go through the sluice. Any experienced gold miner will tell you that the secret to recovering the most gold is to process a lot of material quickly- and a highbanker does just that! A high banker, also called a power sluice, is a piece of equipment that uses a pump to force water through a sluice to mimic the natural flow of a stream.
