employed as the muscovite dispersant in the flotation of muscovite/arsenopyrite mineral system for the first time. SP is a natural antioxidant, color-protecting and environmentally friendly food additive ... for flotation test, particle size distribution analysis and XPS detection. 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 …

This work examines the effects of Custamine 8113 (collector) and Norlig-H (depressant) on the flotation of a muscovite ore from a mineralogical perspective using …

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.

Section snippets Flotation experiments. 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 …

The flotation test results showed that calcium ions can selectively decrease the arsenopyrite floatability. ... the action mechanism of electrochemically modified sodium silicate and muscovite ...

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. Their principal use is for muscovite flotation in alkaline conditions. ... For the optimal test (i.e., flotation time − 12 min, collector dosage – 478 g/t and pH – 2), ...

The performance of the mixed dodecylamine chloride (DDA)/octanol (OCT) surfactants on muscovite flotation was investigated using flotation tests, and their adsorption mechanisms on muscovite and ...

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 ...

Download scientific diagram | Flowchart of flotation test. from publication: Effect of Cu2+ on the Activation to Muscovite Using Electrochemical Pretreatment | In this study, electrochemistry ...

Request PDF | On Jan 1, 2024, Liuyi Ren and others published Enhanced flotation performance and adsorption mechanism on (0 0 2) crystal plane of fine muscovite powder | Find, read and cite all the ...

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).

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 …

O atom was the active site in the flotation of muscovite, and the (131) crystal plane was more likely to adsorb with ODA than (002) crystal plane. Through the simulation results, more (131 ...

2.2. Flotation test. The pure mineral sample of muscovite after grinding was used as original sample for flotation test. The flotation machine is carried out in a 50 mL XFGC hanging tank flotation machine with a spindle speed of 1992 r/min. SDS and SDBS were used as trapping agents for the single mineral flotation test of muscovite. 2 g of …
