Dry separation of particulate iron ore using density ...

Highlights We applied the dry density-segregation in a gas–solid fluidized bed to separate particulate iron ore. The density- and size-segregation is dependent on the air velocity. The density-segregation results in an iron concentration dependence on the height. The dry density-segregation has a potential for the upgrade of the particulate iron ore.
