ABSTRACT
The gas-solid fluidized bed is of many characteristics, one of which is the pseudofluid property with a special density. A particular interest of our review is the discussion of separation research development of gas-solid fluidized beds. The fundamental and importance of dry mineral processing using gas-solid fluidized beds are introduced. On the basis of analyzing parameters which affect the stability and separation performance of fluidized beds, such as the structure of air distributor, properties of medium solids and operating conditions of fluidizing media (air) etc., the separation research status of gas-solid fluidized beds is reviewed in detail. The recent developments, especially the fluidized bed with an external field assisted, including a vibrated fluidized bed and a magnetically fluidized bed, are also reviewed. Lastly, the study direction on mineral separation with fluidized beds is suggested.
