1. Apparatus for use in the separation and processing of a feed material, the apparatus including a cylindrical cyclone tube having, at one end thereof, a feed material inlet for receiving feed material and a first outlet for removing separated fractions of less dense material;

  • and at an opposite end thereof, a second outlet for removing separated fractions of higher density material;

    a means for imparting tangential velocity to the feed material that is introduced through the inlet and for initiating a vortex spiral within the cyclone tube;

    one or more axially spaced secondary inlets located in the wall of the cyclone tube for delivering an externally supplied substance or substances into the cyclone tube;

    one or more stepped edges, orientated within the cyclone tube at an angle 10°

    to 170°

    relative to the direction of the vortex spiral within the cyclone tube;

    wherein the vortex spiral creates an annulus whereby the higher density material migrates towards the perimeter of the cyclone tube and the less dense material migrates towards the core such that separation and/or processing of the feed material is achieved.
