X RAY DIFFRACTION STUDY ON DESILICATION OF DIASPORIC ...

Abstract: The phase transitions of kaolinite and diasporic bauxite during roasting were studied by means of XRD analysis. The desilication mechanism of diasporic bauxite by chemical processing was explained. It was shown that the α SiO 2(quartz) in green ores can not be separated, but the amorphous SiO 2 formed by roasting kaolinite at temperature above 900 ℃ …
