dense media separation for iron ore

dense media separation plants iron ore. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation .

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 Dave = 23.6 mm was investigated as the fluidizing air velocity and the float-sink time were varied.
