Abstract
A textured trough element including a concave surface having a curved profile when viewed from a longitudinal end thereof of marginally larger diametrical extent than the circular cross section of a helical tailings auger. The trough element is positionable in a bottom portion of an auger trough with the concave surface facing and extending partially around a bottom portion of the helical radial outer periphery of the auger such that the auger will convey the tailings on and along the concave surface. The concave surface has a sufficiently rough surface texture for causing tumbling and rolling of at least a substantial portion of the tailings conveyed thereover, for loosening and releasing at least some of any grain partially or fully contained in elements of the tailings.
