the Gaussian 03 [27] and Chemoffice2005 program. The initially molecular modeling of cationic collector molecule was optimized by MM2 and MP3 methods. The obtained geometries were further optimized... of additional cations. Thus cationic surfactants for the kaolinite flotation are proved to be effective. In this work, we chose dodecylamine (DDA), the earliest reported cationic collector for kaolinite......
