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.
