Press and Springer-Verlag Berlin Heidelberg 2011 Abstract: The fluidization behavior of SiO2, ZnO and TiO2 non-magnetic nanoparticles was investigated in a magnetically fluidized bed (MFB) by adding coarse magnets. The effects of both the amount of coarse magnets and the magnetic field intensity on the fluidization quality of these nanoparticles were investigated. The results show that the coarse......

) Abstract: The simultaneous separation and washing of red mud of the leached slurry with high alumina concentration in the sintering process was studied by employing the fluidization technique. The results show that the separation and washing of red mud can be achieved at the same time by fluidization method. When Al2O3 mass concentration of the leached slurry is 240-270 g/L, Na2O mass concentration......
