The spectral region between 800 and 750 cm −1 is very sensitive against the crystallinity and the purity of the kaolinite mineral. Pure kaolinite exhibits two peaks (795 and 754 cm −1) in this region. The XRD pattern of the −53-μm fraction exhibits strong peaks for kaolinite with disappearance of peaks due to quartz and siderite.
