Synergistic effect of mixed cationic/anionic collectors on flotation
The flotation and adsorption of DDA/NaOL at the solid–liquid interface was investigated by flotation tests with muscovite, contact angle measurements and adsorption measurements. The flotation results indicate that the recovery of muscovite could be achieved a maximum value (98.45%) by the mixed DDA/NaOL at α DDA = 0.25 at pH 7.0.
Understanding the effect of mineralogy on muscovite flotation using
Lab-scale flotation tests were conducted on a muscovite ore (9.1 wt.% muscovite) from an industrial mine to determine the effect of varying concentrations of collector and depressant.The feed was wet ground in a laboratory rod mill at 50% solids for 22.5 min to produce a P 80 of 106 μm (Fig. 1). The cell used was a 3 L Denver flotation cell with several …

Flotation tests of single and binary mixed minerals (1.00 g fluorapatite + 1.00 g Muscovite) were carried out using an XFG flotation machine with a specification of 40 mL acrylic plate flotation tank at an impeller speed of 1800 r/min.
Flotation and molecular dynamics simulation of muscovite …
In this study, three kinds of anionic collectors (sodium oleate (NaOl), sodium dodecyl sulfonate (SDS) and naphthenic acid (NA)) were used in combination with dodecylamine (DDA) to investigate the flotation behavior of muscovite under the action of different mixed anionic/cationic collectors, and their mechanisms for adsorption on the muscovite (001) …
Unveiling the enhancement mechanism of Fe ion for muscovite flotation …
For each test, the 5 g of muscovite sample was accurately weighed and placed in flotation cell. The pH of pulp was adjusted using hydrochloric acid (0.1 M) and sodium hydroxide solution (0.1 M). And then, sequentially, the metal ions and collector were added, followed by flotation for 4 min ( Fig. 1 a).
An investigation into the flotation of muscovite with an …
Electroacoustic zeta potential measurements and single mineral flotation tests were used to determine the effect of Custamine 8113 (collector) and Norlig-H (depressant) on muscovite. These results were then compared to those of gangue minerals (feldspar and quartz). Muscovite showed an isoelectric point (IEP) at pH 3.5.
Enhancement mechanism of metal ions on the flotation …
Metal ions have been employed to improve the flotation efficiency of muscovite, yet the underlying enhancing mechanisms remain unclear. In this study, we systematically investigated the improvement in muscovite flotation by adding metal ions with different valence states (K +, Ca 2+, and Al 3+).Flotation experiments revealed that the muscovite recovery rate …
Insight into the Effect of Nanobubbles on Fine Muscovite …
It could be seen from the above conditional flotation test that the change in collector concentration, impeller speed, and the pretreatment of a nanobubble aqueous solution would lead to a change in the flotation recovery rate of fine muscovite.

Muscovite has a typical dioctahedral crystal structure. The atoms arranged in different directions of the crystal lattice will cause the anisotropy of the physical and chemical properties of the muscovite crystal planes, which …
Influence of metal ions on muscovite and calcite flotation: With
It could be seen that the muscovite did not float with sodium oleate as collector and the introduction of Ca 2+ had no influence on its flotation performance. But the introduction of Al 3+ and Fe 3+ significantly changed the flotation behavior of muscovite. Specifically, the addition of Al 3+ allowed the recovery of muscovite to be substantially increased by 20%–60% at pH …
