Abstract
A continuous run sluice box having vibrating and sonic vibration means for concentrating gold or other precious metal, while eliminating the loss of black sands normally accompanying the use of conventional sluices. The sluice box is provided with a sonic vibrating means, and it is mounted for rotation about its own peripheral axis. The sluice includes two parallel channels disposed on either side of a main floor, so that the uppermost channel may be in use, while the lowermost channel is cleaned by directing streams of water and sonic vibration against the clogged riffles, thereby eliminating down time normally involved in periodic cleaning.
