Using the plateau design, only the densest material climbs the grooves in the ramp, is cleaned, and reports to the high grade discharge. Less dense, higher volume material (as in sulfides in gold ore) forms a band at the base of the ramp, reporting to the middlings tray. The lightest material stays behind and reports to the tailings tray.
Other design features of the table were added to minimize turbulence, hence higher fine gold recovery to <325 mesh. Sloped grooves are machined into the rubber top, replacing high-turbulence riffles. There is a smooth back and forth motion to move the material across the table without bumps or jerks. Adjustable water flow helps control the separation of various density components. The table is easy to operate and very forgiving for the new user.
