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.

In the case of recirculating sluices they can be operated in arid desert areas with very little water. The power sluice / highbanker can work remote placer gold deposits hundreds of feet away from the water source. Rather than haul material to the water, you can bring a lightweight, efficient power sluice directly to the source. 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.
