A novel approach for flotation recovery of spodumene, mica and feldspar from a lithium pegmatite ore. J Clean Prod, 174 (2018), pp. 625-633.

The following combination, for a North Carolina deposit, involves two steps of flotation. Gangue minerals such as mica, feldspar, and quartz are first floated after grinding the ore and de-sliming by treatment with a cationic collector in alkaline circuit, and with starch or dextrine, to depress spodumene and iron minerals.

Feldspar recovery in the concentrate, being 86.67% without dewatering/washing increases to 94.58% after three stage dewatering/washing between mica and metal-oxides flotation stages.

A pegmatite ore (with the Li 2 O grade being 1.56 %) was obtained from the mines of western Sichuan, China. The XRD and multi-elemental chemical analysis results of the ore were presented in Fig. 2 and Table 2.It can be seen in Fig. 2 and Table 2 that the valuable mineral was spodumene, and the primary gauge minerals were feldspar, quartz and …

Because spodumene and gangue minerals, such as feldspar and mica, have similar surface properties, that is, the Al site acts as the active center, the flotation separation of spodumene and gangue minerals using traditional anionic collectors, such as sodium silicate, naphthenic soap and fatty acid, is inefficient (Moon and Fuerstenau, …

This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves. Much of the published information on feldspar flotation relates to …

This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, …

The flotation behavior of muscovite mica is different from the other oxides and silicates (Fuerstenau and Pradip, 2005). Similarly to kaolinite, muscovite mica belongs to phyllosilicate mineral. ... Adsorption mechanism of mixed cationic/anionic collectors in feldspar–quartz flotation system. Journal of Colloid and Interface Science, 306 (2 ...

The K-feldspar flotation was performed in alkaline environment (pH 10.5–11.6) with only the addition of NaOH as a modifier and non-ionic Brij58 as a frother, on a fluorine-amine activated bulk ...

A test on the +250 µm fraction, which was firstly ground then deslimed at 50 µm before mica and feldspar flotation stages, produced a quartz product assaying 99.5 wt% SiO 2 and only 0.3 wt% Al 2 ...

The flotation tests demonstrated that the best process conditions for the flotation of iron-bearing minerals, such as mica, from quartz and feldspar are a pH of …

Feldspar is a common occurrence in spodumene ores, and has applications in glass making. K-feldspar is a key component in the manufacturing of ceramic materials. Froth flotation is the main method used for the recovery of feldspar from lithium ores because its flotation properties are well understood (Fuerstenau and Pradip, 2005). …

In this paper, a complete scheme aimed at improving the flotation performance of spodumene and comprehensively recycling mica and feldspar from …

Abstract The flotation process and magnetic separation are the most common methods for feldspar beneficiation containing approximately 0.4% Fe2O3 and 0.04% TiO2. A model MIH (13) 111-5 Induced Roll dry high-intensity magnetic separator was used in this investigation to produce high-quality feldspar concentrate, and …

On the contrary, the availability of huge potassium-bearing rocks/minerals (like nepheline syenite, feldspar, mica, glauconitic sandstone) in these countries containing around 4–17% K2O would be a prospective for commercial production of potassium. ... Sekulic et al. reported a comparative study of feldspar flotation using two commercial ...

Also, if little or no mica is present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture.

For mica flotation, sodium carbonate (Na 2 CO 3) was used as pH adjuster, and sodium oleate/octanol with mass ratio 9/1 (NaOT) and dodecylamine (DDA) were used as mixed collectors. Subsequently, quartz-feldspar separation was carried out using sodium hydroxide (NaOH) as pH adjuster, magnesium chloride (MgCl 2 ) as activator, …

The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na 2 SiF 6; SF) as a selective depressant was investigated.Moreover, the influence mechanism of SF on the selective …

Powering the industries of tomorrow with ultra-pure quartz essential to the technology advancing humanity. With our progressive approach and incomparable quality, our quartz is behind the world's foremost solar, optical fiber, and semiconductor technologies.

The flotation tests demonstrated that the best process conditions for the flotation of iron-bearing minerals, such as mica, from quartz and feldspar are a pH of 8.3, a mixing ratio of NaOL/BHA/A CO of 3:1:0.05, and a dosage of 300 g/t.

Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product. Depressing the feldspar and reflotation of the beryl into a high grade marketable concentrate (at least 8.0% BeO) is the usual procedure.

The potential application of different cation collectors in the flotation concentration of mica, feldspar and quartz sand has been investigated. Raw materials (Bujanovac and Ub) from two localities in Serbia were used. The results showed that for flotation of feldspars, Aero 3030C performed better than Flotigam DAT.

The effect of hydrofluoric acid (HF) pretreatment on flotation of feldspar and quartz using dodecylamine (DDA) as collector was investigated by micro-flotation, zeta potential, pyrene fluorescence …

The selectivity in flotation separation of spodumene from other pegmatic aluminosilicates such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult.

An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be …

Flotation tests show that the amine concentration ought to be kept lower than 1.47 × 10 −5 mol/l (≈5 ppm) to prevent feldspar loss during metal-oxides flotation stage and hence dewatering/washing operation after mica flotation seems to be a crucial step. Feldspar recovery in the concentrate, being 86.67% without dewatering/washing ...
