ABSTRACT:
A chute is formed by a bottom wall and side walls, and the bottom wall is provided with cross grooves for catching ore particles. The bottom and front walls of the grooves are formed on about the same radius of curvature with the curvature of the front wall forming an undercut under the feed edge of the grooves. The rear wall of the grooves leads from the bottom wall in a straight line inclined upwardly in a discharge end direction. Ore containing material which is fed down the chute is separated out in the grooves by a back eddy developed by the particular shape of the grooves.
