The effects of some collectors and modifying agents with varying pH on the ¦Æ-potential and flotation behavior of fluorite were studied. The zero point of charge (ZPC) of fluorite is located at pH 6.5. The pos. charge of the fluorite surface is increased by increasing the Ca2+ ion concentration while the F– ion has almost no effect on the ¦Æ-potential. H+, OH–, and Ca2+ are proved to act as potential-determining ions. The ZPC is shifted to the alk. range when the cationic collector dodecylammonium acetate (I) is added. The fluorite surface is charged neg. in the whole pH range in the presence of the anionic collector Na dodecyl sulfate (II). The Hallimond tube tests show that I is effective on the neg. charged surface and II on the pos. charged surface; therefore, the adsorption on the surface occurs by electrostatic attraction. In the presence of Na oleate, the fluorite is neg. charged due to the adsorption of the oleate species and the floatability is enhanced; however, the most-effective flotation is achieved in the neutral pH range at low concentration, ¡Ü10-5M. There is little decreasing floatability up to pH 10, though the Na metasilicate concentration was increased to 10-3M.
