Flotation of mica minerals and selectivity between muscovite and biotite while using mixed anionic /cationic collectors

Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of sodium oleate and dodecylamine acetate has been described. Muscovite is found to float in preference to biotite, when the pulp is initially conditioned with oleate followed by amine …

Abstract. Low-grade limestone samples from Northern Telangana, India were put through to beneficiation by flotation to upgrade the CaO value by minimizing the unwanted (gangue) minerals for ...

A flotation column was used for this study, as the flotation column can produce higher grade concentrates compared to conventional flotation cells, while requiring lower flotation time and stages, particularly for fine particles (< 75 μm) [29, 30]. The performance of the flotation not only includes the grade recovery of fluorspar but also …

- 3 - ABSTRACT This study was aimed at recovering lithium from china clay waste using a combination of froth flotation, magnetic separation, roasting and leaching.

Flotation tests were carried out on ore samples bearing muscovite, biotite and quartz. Using sodium carbonate and calcium lignin sulfonate, Browning and Adair …

Flotation of pure minerals was performed to characterize the conditions for separation of silicates (palygorskite, quartz, orthoclase, …

The flotation test was started and continued for 6 min. The froth product and the product in the flotation cell were sep-arately dried and weighed to calculate the recovery of the concentrate. 2.2.2. Zeta potential tests The single-mineral sample was ground to a particle size of less than 5 μm. For each test, 0.02 g of the ground sample

Then, the collector BX (30 mg/L), and frother MIBC (20 mg/L) were added to the flotation cell sequentially, with 3 min stirring after each addition [33]. Besides, the spindle stirring speed was 1950 r/min and the air flow rate was kept constant at 0.4 m 3 /h. For the kinetic experiments, the flotation process was divided into seven stages in ...

The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell.

The test was carried out in the flotation cells (XFD-63) with 500 g sample. First, adjust the pH of the suspension with sodium carbonate for 2 min, add depressant and stir for 2 min, then add ...

Jan 25, 2018 Flotation equipment is all kinds of flotation cells. Commonly used heavy media is ferrosilicon, magnetite, pyrite, etc. Shandong xinhai mining technology and equipment Inc. manufactures all kinds of diaphragm jig, sawtooth jig, and flotation machines, we can provide all kinds of phosphate ore machines, and make phosphate ore …

Moreover, the muscovite and biotite (+20–100 μm) morphology used in this work can explain the low flotation recovery under high turbulent condition in the mechanical flotation cell while the results of Rao et al. (1995) were obtained in a Hallimond tube. The hydrodynamics flotation conditions between the two studies were not identical and ...

Effect of metal ions on the flotation separation of biotite from quartz using mixed anionic/cationic collectors. Metal ions have a great effect on biotite and quartz flotation. …

Split of spodumene flotation into coarse particle flotation (in cells such as the Eriez Hydrofloat) and fine particle flotation (in conventional flotation cells) The key flotation flowsheet stages include the following: Primary grinding. Grind sizes such as F 100 300 μm, or finer, based on spodumene liberation characteristics (see Fig. 1).

Ralph and James patented the flotation of mica to concentrate muscovite separating it from biotite and other gangue minerals.
