Shaker Tables

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.
