Effect Of Dry Grinding On The Physicochemical Properties ...

Mar 01, 2012 The degree of amorphization calculated from X-ray diffraction (XRD) data of silica increased with grinding time. The band intensities of Si O Al and Al OH were decreased by the grinding process, which was beneficial to the subsequent leaching. Morphologic and structural studies revealed that the crystalline structure of kaolin residue was destroyed during grinding.
