ABSTRACT:
An improved continuous run sluice box having a sonic vibration and ultrasonic vibration means for concentrating gold or other precious metals while eliminating the loss of black sands containing other valuable fines normally accompanying the use of conventional sluices. The sluice includes a novel type riffle construction including a vertical wall and a sloping wall leading to a collecting area having a nylon cloth screen positioned between coarse and fine metallic screens which facilitates both the collection of the fines and the release of the same during flushing operations.
