Description	Two samples of pure kaolinite with a significant difference in their crystallinity, a commercial kaolin sample with 20 wt.% of illitic component and one sample of illitic clay with up to 20 wt.% of kaolinitic component were used in dissolution kinetic experiments and the results compared to data obtained from the leaching of sandstone matrix kaolinites under laboratory conditions. The mineralogical and chemical compositions of all samples were characterised using X-ray diffraction and X-ray fluorescence techniques. Specific surface area was measured by the gas adsorption (BET) method. Structural disorder of kaolinite given by the extent of the sheet translations was calculated from the X-ray diffraction data (the 'Hinckley index'). Dissolution experiments in continuously stirred suspensions (with solid/liquid ratio=1:100) were performed in 0.5 and 5 M solutions of H2SO4 at 25 and 40 degreesC, respectively, and the reaction rate was calculated from the measured concentrations of Al and Si in the soluti Two samples of pure kaolinite with a significant difference in their crystallinity, a commercial kaolin sample with 20 wt.% of illitic component and one sample of illitic clay with up to 20 wt.% of kaolinitic component were used in dissolution kinetic experiments and the results compared to data obtained from the leaching of sandstone matrix kaolinites under laboratory conditions.
