Description


Each machine is a complete portable plant; there is no need for additional screens or sluice boxes! At the top is an extreme duty grizzly bar section that will take up to 24-inch rocks (91 cm). Classification begins when the material is placed on the grizzly bars, and high-pressure water separates the sub-1” (25.4 mm) material from the large rocks. Next, the screen deck further classifies the material, and sub-.25” (6.35 mm) material drops into the sluice boxes, remaining sub-1” material passes through the nugget trap into the final.

Next, the screen deck further classifies the material, and sub-.25” (6.35 mm) material drops into the sluice boxes, remaining sub-1” material passes through the nugget trap into the final riffle set for capture, and larger rocks get discarded.

 



Structure


Working principle

 

The sluicing system has three boxes that are independently adjustable, and with anywhere from 2 feet of sluice box on our 50-ton units to 4 feet of wider boxes on the 200-ton units, gold recovery is excellent. It often exceeds 95%, even with fine gold down to 200 mesh! What’s the key to such remarkable recovery? Science. Our design was based on the performance data found in a landmark technical report on sluice boxes and riffle systems.
