  • Flotation de silicating from diasporic bauxite with cetyl

    Using cetyl trimethylammonium bromide CTAB as collector the flotation de silicating from diasporicbauxite was investigated And the Zeta potentials and contact angles of silicate minerals and diaspore were also studied The results show that in the presence of 2 10−4 mol L−1CTAB the surface charges of pyrophyllite kaolinite and illite become more positive and the contact angles of
