The dissolution process of kaolinite in NaOH solution was confirmed through changes in morphology. Kaolinite particles were obviously surrounded by granulated aluminosilicate particles (Fig. 6 (a), (b)). It seemed that the generated aluminosilicate had no intact crystal structure and looked more like a transitional …
Accordingly, Kaolin has been recognized as being one of the localized potent hemostatic agents that could effectively stimulate the blood clotting process 10. Kaolin or china clay is mainly consisting of mineral kaolinite and aluminium silicate 11. Margolis 12 found out for the first time the capability of kaolin in blood clotting stimulation.
Kaolinite is a common gangue mineral in iron ore and sodium silicate has been used widely as a dispersant of silicate gangue minerals including kaolinite in various iron-ore flotation methods over a wide range of pH. Its actual dispersive effect on kaolinite under iron-ore flotation conditions has received very limited attention, however.

Once chemical activation becomes more intense, kaolinite areas disappear due to the dealumination process. Consequently, the unmasking of the quartz peaks starts. For example, the 453 cm −1 band is slightly diminished compared to other kaolinite peaks due to the around 450 cm −1 Si–O vibrations of kaolinite and quartz coexistence [ 65 ].
