This book represents the flocculation behaviour of two different clayey sample associated with borax crystal. Author firstly discussed the problem related the high degree of colloidal stability of the samples and then he suggested the beneficial chemical and physical parameters for the efficient removal of these fine particles from borax-buffered aqueous suspension. Also, the physicochemical properties of these clayey samples were explained with the help of the Zeta-Potential measurements and ATR-FTIR studies.
