Gold Wash Plants for Sale

Each machine is a completely 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, the remaining sub-1” material passes through the nugget trap into the final riffle set for capture, and larger rocks get discarded.

The sluicing system has three independently adjustable boxes, and with anywhere from 20 feet of sluice box on our 50-ton units to 40 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 a remarkable recovery? Science. This portable gold mining equipment was based on the performance data in a landmark technical report on sluice boxes and riffle systems.
