Flotation Chemistry of Hematite/oleate System
Oleate flotation characteristics of hematite have been investigated in thjs study under a wide range of experimental conditions of pH, temperature, ionic strength and collector concentration. The study revealed the following major features of this system which include: (a) a maximum in floatability in the neutral pH range; (b) an increase in the flotation response of hematite with increase eith...
متن کاملFlotation Behaviors of Perovskite, Titanaugite, and Magnesium Aluminate Spinel Using Octyl Hydroxamic Acid as the Collector
The flotation behaviors of perovskite, titanaugite, and magnesium aluminate spinel (MA-spinel), using octyl hydroxamic acid (OHA) as the collector, were investigated using microflotation experiments, zeta-potential measurements, Fourier transform infrared (FT-IR) analyses, X-ray photoelectron spectroscopy (XPS) analyses, and flotation experiments on artificially mixed minerals. The microflotati...
متن کاملTECHNICAL NOTE THE EFFECT OF pH MODIFIER ON THE FLOTATION OF CELESTITE WITH SODIUM OLEATE AND SODIUM METASILICATE
This paper studies the influence of two pH modifiers, namely sodium hydroxide (NaOH) and sodium carbonate (Na2C03), on the flotation of celestite ore using sodium oleate as the collector and sodium silicate (Na2SiO 3) as the depressant. The use of Na2CO 3 provides the best results for the concentration of celestite, under the same experimental conditions. © 1998 Elsevier Science Ltd. All rights...
متن کاملSynergetic Effect of the Mixed Anionic/Non-Ionic Collectors in Low Temperature Flotation of Scheelite
The synergetic effect of four octaphenyl polyoxyethyienes (TX) on low temperature flotation of scheelite at 9–11 ◦C was investigated through flotation experiments, and the adsorption mechanism was studied by way of surface tension, zeta potential, and adsorption measurement. The results show that the presence of the four octaphenyl polyoxyethyienes can improve scheelite flotation in a low conce...
متن کاملConductometric Study of the Thermodynamics of Micellization of Sodium dodecylsulfate (SDS) in the Presence of Some Aromatic Ammonium Salts
The effect of three organic aromatic salts - Phenyltrimethylammonium (PhTMAB), benzyltrimethylammonium (BzTMAB) and benzyltrimethylammonium (BzTEAB) bromides - on the micellization of sodium dodecylsulfate has been investigated by conductometric method. The critical micelle concentration (CMC) values were found to decrease with increase in the concentration of the aromatic ammonium salts. Therm...
