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.
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 …
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 …
Modifiers are usually not required for muscovite flotation However, in some cases, it can be of interest. Most used modifiers for muscovite flotation are activators.

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.
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 experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC).
With cationic collectors DAA (1 × 10 −4 M), the flotation recovery of muscovite mica decreases with increasing in pH. The recovery of muscovite mica with DAA changed in the range of 80–50%. The flotation behavior of muscovite mica is different from the other oxides and silicates (Fuerstenau and Pradip, 2005). Similarly to kaolinite ...

With the increasing demand for mineral resources, it is necessary to further recycle some fine muscovite which are not of high quality and discarded after the first development. This study was to improve the recovery of fine muscovite (-20 μm) by introducing of nanobubbles (NBs). A series of techniques including flotation test, mineral adsorption capacity measurement, Zeta potential ...

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 …

Single-mineral flotation tests showed that the muscovite-collecting power of the mixed DDA/alcohol (OCT, DEC, or DOD) system was stronger than that of the pure DDA system.
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).
