A method and apparatus for the wet gravity concentration of particulate ores in which a cascaded series of concentrators may be arranged in a matrix array from a basic triangular unit comprising a first concentrator for dividing a pulp stream into two sub-streams of differing concentration and a pair of subsidiary concentrators for respectively dividing the sub-streams, the subsidiary concentrator dividing the richer sub-stream being arranged to remove at least part of its enriched stratum without intruding substantially into its feed grade stratum while the subsidiary concentrator dividing the poorer sub-stream is arranged to remove at least part of its depleted stratum without intruding substantially into its feed grade stratum. The method and apparatus are described with reference to both tray and cone concentrators. |
