Sep 01, 2010 The dry dense medium separation of iron ore based on floating and sinking of ore particles in a gas–solid fluidized bed was investigated using zircon sand as the fluidized medium. The float-sink of ore particles with mean size D ave = 23.6 mm was investigated as the fluidizing air velocity and the float-sink time were varied.
