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 …
The purpose of this study was to investigate the separation characteristics of mica from feldspar in a shaking table and the Reichert spiral by determining the role of the shape …
How to obtain high-grade feldspar efficiently from the feldspar resources is very essential for its comprehensive recycling and sustainable development. Flotation separation (direct or reverse) followed by de-sliming and magnetic separation is the most important beneficiation technique for upgrading feldspar.
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.
For many of the operated feldspar deposits, separation of feldspars from accompanying mineral phases (phyllosilicates such as micas or clay minerals) and removal of colourants make part of raw material processing flow …
Considering the appreciable content of mica and feldspar in the lithium ore from Jiajika, recycling mica and feldspar during spodumene beneficiation is worthy of consideration whether from increasing economic benefits or reducing the burden of …

Keywords: Feldspar, Selective separation, Weathered granites, Flotation, Monovalent salts Granite and granodiorite deposits are widely scattered throughout in Eastern Black Sea region of Turkey. These granitic bodies also contain considerable amounts of quartz, Na-feldspar, K-feldspar, mica and other color-imparting ferruginous impurities.
In the present study, effects of several operating parameters on the separation efficiency of mica from feldspar by spiral concentrator were investigated.
Laboratory application of flotation to the seraration of oligoclase feldspar from quartz yields good results. Quartz in excess of 3 percent remained in only two of the seventeen samples studied.
In the present study, effects of several operating parameters on the separation efficiency of mica from feldspar by spiral concentrator were investigated. For this purpose, an albite ore containing mica was treated in a full scale Reichert spiral (model HG7) under various test conditions. During the study, particle size distribution, solid contents of the feed, feedrate …
Thus, methods for the successful separation of lithium-bearing mineral phases from gangue minerals (such as quartz and feldspar) are urgently required. Froth flotation is a desirable method for the separation and recovery of lithium minerals from various surrounding gangues during mineral processing.
A novel green cationic surfactant Poly (propylene glycol) bis (2-aminopropyl ether) (PEA) with multiple amine groups was utilized as a collector for flotation separation of quartz from feldspar-quartz associated ore (FQA) without acid (particularly, HF) and alkali. The collecting performances and the adsorption mechanisms of PEA on the …

Adding flotation to the magnetic separation process can further reduce the iron content in the granite, as well as remove mica, iron, and titanium mineral impurities, resulting in feldspar and quartz concentrates.
This paper aims at evaluating several electrostatic separation techniques that could be effective for the recovery of mica flakes from pegmatite ores characterized by grain sizes <0.5 mm: 1 ...

The Na + from sodium chloride behaves as a source of depressant for Na-feldspar so that an effective separation occurs between Na-feldspar and K-feldspar. Vidyadhar et al. reported the use of mixed cationic (alkyl diamine) and anionic (sulfonate or oleate) collectors for better separation of feldspar from quartz. The study also indicates …
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 …
Gravity separation can be used for mica–feldspar separation because mica generally takes the form of flaky shapes, which are pliable, resilient, and tough. Pinched sluice was used to remove flaky mica minerals from albite, and the …
