Abstract: The invention provides a cyclone adapted for use in a dense medium separation process comprising an inlet chamber having a tangential raw material feed inlet, a vortex finder extending into the inlet chamber, and defining a low gravity fraction outlet for a low gravity fraction of separated material, a conical section opposed to the vortex finder extending and converging in a direction away from the inlet chamber, an outlet chamber extending co-axially with the conical section and in a direction opposed to the inlet chamber and providing an unobstructed flow path to a high gravity fraction outlet for a high gravity fraction of separated material being disposed generally tangentially relative to the outlet chamber.
