Tromp Curve - Example of Partition Curve The efficiency of separation depends on the ability to separate material of sG close to that of the medium This can be represented by a Tromp or Partition curve, which relates to the partition coefficient (ie the percentage of feed material of a particular SG which reports to the sinks (or floats) product plotted against SG)

Classification and centrifugation | FL Within the cyclone, weight and gravity separate the lighter material from the heavier material, as the media’s buoyancy effect forces the lighter solids to the hydrocyclone’s centre, where they float upward and out through the vortex The heavier, denser material spirals to the outside of the cyclone, and sinks down towards the apex exit
