“…The electrostatic adsorption mechanisms of quaternary ammonium salts have been widely reported by various researchers [44,45]. To illustrate the effect of the adsorption of TTPC on the electrokinetic behavior of quartz surface, the zeta potential of quartz and magnetite as a function of pH values were measured in the presence and absence of TTPC or DTAC.…”

Abstract:In this work, tributyltetradecyl-phosphonium chloride (TTPC), has been first introduced to be a novel and efficient cationic surfactant for cationic reverse flotation separation of quartz from magnetite. The first-principles density functional theory calculations, Zeta potential measurements and adsorption isotherm measurements consistently predict that TTPC may be a promising collector that is better than dodecyl triethyl ammonium chloride (DTAC), based on the facts that TTPC and DTAC both prefer to physically adsorb on the quartz surface owing to electrostatic force, but the active part (P + (C 4 H 9 ) 3 ) of TTPC takes much more positive charges than that (N + (CH 3 ) 3 ) of DTAC. The micro-flotation and Bench-scale flotation results further verify that TTPC presents a stronger collecting power and much better selectivity for iron ore reverse flotation in comparison to the conventional collector DTAC. Furthermore, the corresponding adsorption mechanism of TTPC on the quartz have also been investigated in detail. This work might show a good example to discover a potential candidate collector by analogy with a known excellent collector based on reasonable prediction.

“…bearing surface species, the interaction of IL cationic moiety might take place physically via electrostatic attractions provided the mineral surface is negatively charged as proposed in Figs. 14 and 15(a) [84,85]. Also, lateral chain-chain associative interactions, reminiscent of the adsorption of surfactants at solid/solution interface, may be invoked to explain the surface interaction of the IL cationic moiety.…”

Abstract. Traditional processing of kaolin is achieved by dispersion of the mined ore and classification by means of multistage hydrocyclones. The inefficiencies inherent to cyclones produce a middling product that is commonly disposed back to the quarry. In this research recovery of kaolinite from tailings of the Zonoupz kaolin washing plant, which is located in Iran, was investigated by cationic flotation. Flotation experiments showed that flotation of kaolinite from tailings was much better in an acidic than in an alkaline medium containing cationic collectors.
