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 …

In our latest study, surface dissolution of minerals has been found to be important in the flotation of spodumene. This study provides further information in the role of NaOH in the flotation separation of spodumene from feldspar and quartz using size distribution analysis, micro-flotation experiments, AFM imaging, X-ray photoelectron …

Spodumene flotation stands as the most commonly used method to concentrate lithium minerals. However, it faces significant challenges related to low collector recoveries and …

b) Hard rock spodumene deposits are comprised of lithium-bearing, aluminium silicate mineral which mostly occurs in lithium-rich pegmatites (granite-like igneous rock composed of quartz, feldspar and mica).

The flotation behaviors of PPPDA on the separation of spodumene from feldspar and quartz were investigated through single mineral flotation experiments.

Surface dissolution behaviors of spodumene, feldspar, and quartz, and its influences on their surface properties and flotation separation were investigated when pretreated in deionized water (DI water), NaOH solution and HCl solution individually. The surface components of minerals, such as Si and Al, had shown different dissolution …

Most flake mica is obtained as the major marketable product by crushing and milling pegmatites. To a lesser extent, mica is produced as a byproduct of feldspar and spodumene.

A typical pegmatite deposit can contain quartz, sodium-feldspar, spodumene, lepidolite, petalite, lithiophilite, microcline, and variable amounts of muscovite (1-5%).

In the context of collector development during the year 2021, Ruiqi Xie and their research team conducted a study on the behavior and flotation mechanisms of α-bromo dodecanoic acid (α-BDDA) in the flotation separation of spodumene from feldspar and quartz using Ca 2+ as an activator.

Mixed feldspar, spodumene, mica and quartz are mined from hard rock, open pit deposits and recovered by flotation from the fresh pegmatite type ores. Potash feldspar, mica, …

Semantic Scholar extracted view of "Effects of metal ions on the flotation separation of spodumene from feldspar and quartz" by Ruiqi Xie et al.

Spodumene is one of the important lithium resources, so it is of great significance to concentrate it. Beneficiation methods of spodumene include magnetic …

The flowsheet illustrated is typical for the average feldspar ore containing quartz, mica, garnet and other iron bearing silicates normally encountered in pegmatites or large dykes of alaskite-granite. Equipment requirements and flotation conditions should always be established by a comprehensive laboratory testing program.

Since the major gangue minerals of spodumene are quartz and feldspar, flotation becomes the most important way to concentrate spodumene.

Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 ( O'Meara, 1939 ). (1979) reported that HF creates a large difference in the minerals ...

Spodumene is one of the main sources of lithium. It is produced in muscovite-type and lepidolite-type granite pegmatites, and is a metasomatic mineral in the process of pegmatite action. It often coexists with lepidolite, beryl, niobium-tantalite, tourmaline, muscovite, etc., and belongs to silicate minerals with these gangue minerals. In …

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 (Na2SiF6; SF) as a selective depressant was investigated. Moreover, the influence mechanism of SF on the selective …

The effects of Ca (II), Mg (II), Cu (II), and Fe (III) on the flotation separation of spodumene from feldspar and quartz were investigated by single-mineral and artificial-mixed-ore flotation experiments using α-bromododecanoic acid (α-BDDA) as a collector. At pH≈7, Ca (II), Mg (II), and Cu (II) selectively improved the flotation of spodumene, …

Most pegmatites have quartz, feldspar, and mica, with a silicic composition similar to granites. However, this texture can be shown by mafic rocks like basalt, gabbro, syenite, etc.

Hard rock lithium deposits consist of pegmatites containing lithium -bearing minerals along with other silicate minerals such as feldspars, micas, and quartz . Typically, the primary lithium mineral in hard rock deposits is spodumene, an alumino-silicate mineral with the chemical formula Li 4 Al 4 [SiO 3] 8.

Pegmatites of this type have the following characteristics: albite and quartz dominant over spodumene and K-feldspar, and a homogeneous and symmetric …

"Spodumene mineral is a source of lithium for lithium ion batteries. Thus, the production of a spodumene concentrate with an approximate grade of 6% Li2O is targeted. Traditionally, spodumene is concentrated by froth flotation using fatty acid as the collector. Amine collector can also be used to float mica ahead of spodumene as required or …

Pegmatite is a coarse-grained igneous rock, renowned for its exceptionally large crystals, Composed mainly of quartz, feldspar, and mica, it shares a similar composition to granite but differs significantly in its texture.

It is worth noting that lithium mineral such as spodumene is slightly heavier as compared to silicate gangue minerals present in the hard rocks including pegmatites-quartz (2.65), feldspars (2.6 ...
