ABSTRACT OF THE DISCLOSURE A shaking table for ore-dressing, having riffles (50) on its deck, (10), has uniform planar orbital motion imposed on it to cause the riffles to oscillate, and for a standing wave system (71) to be created between the riffles. The continued planar orbital shear forces acting on the standing wave system causes sharp separation of the material fractions which are discharged continuously from the deck. The slope of the deck and riffles and the configuration of the riffles are critical. The slope of the deck is set empirically by estimating the approximate slope appropriate to the parameters of the material being treated and of the motion imparted to the deck; and the final adjustment is made by slewing the deck in its own plane to obtain an optimum result. For a frusto-conical deck, the adjustment is made on a flat deck and the frusto-conical deck is constructed accordingly. The deck may have rectilinear or curvilinear motion imparted to it, superimposed upon the orbital motion.
