Lastly, some of the fine particles were further ground to ~5μm
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 …
Muscovite has been applied in construction materials, paint feed and paper industry, due to its advantages of excellent heat insulation, elasticity and toughness [4], …
The flotation separation of muscovite from quartz was investigated using mixed sodium oleate/dodecylamine acetate (NaOL/DDA) collectors. The experiments were conducted on single minerals and on a ...
In each flotation test, 2 g of a muscovite sample and 35 mL of deionized water were used. Reagent grade HCl and NaOH were used to adjust the pH. After adding the required reagents, the pulp was conditioned for 3 min, followed by a flotation collection period of 3 min. The froth products and tails were separately weighed after filtration and ...
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 …
Flotation-introduced nanobubbles were expected to be an efficient and economical method to recover fine muscovite. This study aimed to explore the mechanism of the change appearing in flotation …

In this study, electrochemistry pretreatment flotation of muscovite was carried out and the flotation behavior and mechanism of muscovite in the system of sodium oleate and Cu2+ion was characterized by solution pH value detection, solution conductivity detection, zeta potential, infrared spectrum and the electronic energy spectrum. The results …
The flotation results indicate that the recovery of muscovite rapidly decreases when the pH increases in the presence of only DDA, whereas the recovery of muscovite is high (> 77%) over a wide ...
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.
