ABSTRACT:
A Process and Apparatus for use in concentrating an aggregate mixture of particles, such as minerals and non-minerals wherein the mixture is introduced onto an inclined endless conveyor adjacent one edge of the incline and is advanced along or parallel to the incline while water is flowed across the inclined surface and the aggregate mixture during the advancement causing the lighter particles to flow with the water down and off of the inclined conveyor while the heavier particles cling to and are advanced with the conveyor surface to a collection area. The endless conveyor includes a plurality of slightly raised ribs on the upper surface which define recesses therebetween for catching and holding the heavier particles during advancement of the conveyor. The raised ribs can be formed into a number of various patterns. The endless conveyor also includes a plurality of horizontally spaced, downwardly projecting tits which form a reduced friction support surface and conveyor engagement drive means. The water is sprayed from a plurality of spaced jets which can be arranged for directing streams transversely across the conveyor or longitudinally along the conveyor.
