dense media separation on iron ore

Dry dense medium separation of iron ore using a gas–solid ...

2010-9-1  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.

Dense Medium Separation - An Effective and Robust Pre ...

2018-2-20  Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
