An apparatus for classifying particulate material comprising at least one tank for receiving a feed slurry, means for introducing water into a lower region of the at least one tank whereby water is caused to flow upwardly and through the feed slurry contained therein, whereby hydraulic separation takes place within the at least one tank with particles of lower settling velocity progressing upwardly and into means for effecting discharge of an overflow fraction from the at least one tank, and particles of greater settling velocity progressing downwardly to a lower region of at least one tank, wherein said feed slurry is introduced into the at least one tank in an upwards direction. |
