. The defrothing mechanism was studied through mensurating surface tension and Zeta potential of the pulp after adding CA. It is found that the changing of surface tension and hoisting of Zeta potential may... by the flotation method[2]. The flotation methods of phosphate ore include direct flotation, reverse flotation, direct-reverse flotation, reverse-direct flotation and so on[3]. Siliceous phosphate ores......
, increasing the density of negative charge on the aluminosilicate surface and leading unpronounced positive charge to increase on the aluminosilicate. By combining the flotation tests, Zeta potential and FTIR...; (c) Pyrophyllite 3.2 Zeta potential results The floatation capability is enhanced notably with SAG8 as collector for the three aluminosilicates, as mentioned above......

and weak alkaline conditions. The interaction mechanism of DLZ in flotation of chalcopyrite and pyrite was investigated through flotation experiments, zeta potential measurements and FTIR. 2... (or depressant calcium oxide) and frother in turn, and the conditioning time was 2, 3 and 1 min correspondingly. The flotation time was 3 min. 2.3 Zeta potential measurement The zeta potentials were measured......
floatability with Gemini cationic surfactants as collectors over a wide pH range, while BDDA showed a stronger collecting power than EDDA. FTIR spectra and zeta potential analysis indicated that the mechanism... of density functional theory (DFT) at B3LYP/6-31G (d) level demonstrated the stronger collecting power of BDDA presented in the floatation test and zeta potential measurement. Key words: aluminosilicate......
test using cationic collector (dodecylamine). Adsorption examination, Zeta potential measurement and Fourier transform infrared (FTIR) spectroscopy were used to clarify the role of the surface charge.... The pH was adjusted and measured. The starch stock solution was added to this mixture, followed by stirring for 3 min. Then, the Zeta potential was determined by a Brookhaven ZetaPlus Zeta potential......
onto mineral surfaces through electrostatic force. It was proved that the Zeta potential of the minerals conducted with 12-4-12 becomes much more positive. Whereas, in the region where the mineral..., and the results shown in this work were the averages. 3 Results and discussion 3.1 Flotation behavior of pure minerals Fig.1 presents the influence of a Gemini collector concentration on the floatation......
-CO-HA+H2O When solution pH is lower than the PZC (the pH where Zeta potential of minerals is zero) of magnetite, that is 4.7, the Zeta potential of magnetite is positive due to protonation, then ligand... value study Zeta potential, often, can be used to estimate the likely effect of various adsorbates on the properties of minerals. The Zeta potential versus pH curves respectively matching the suspension......
