The bubble behaviour has been studied in bubbling fluidized bed composed of the binary mixtures of titanium slag and carbon particles by analysis of pressure time series. The results show that the IOP analysis method can effectively filter out most of the compression wave components at low jetsam fraction and small light particles, but can't effectively remove the compression wave components at high jetsam fraction and large light particles in binary particle fluidized bed. IOPxy functions is significantly affected by the mixed state of binary particles, which means that bubble behavior depends on the segregation/mixing of binary particles in fluidized bed.
