The red mud from Bayer process is available to produce cement. In this situation the mechanism of the calcination of red mud is studied by means of the fluidizing calcination. The dehydration of the red mud is similar to that of 3CaO・Al_2O_3・6 H_2O. The coagulation of red mud with the dimension 0.5 to 2mm in diameter occurs at above 400℃. This is preferable to maintain the calcination of red mud in fluidizing bed. At 800 to 850℃, the release of the combined water in red mud is dependent upon the rate of diffusion of steam through the dehydrated layer.
