The feldspar containing ores are relatively complex and equally contain mica, spodumene, quartz, and other ferro silicate. The ore reserves of feldspar worldwide are large but supplies of pure feldspar are not sufficient. In most of the cases, beneficiation of feldspar ores involves flotation.
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). Beryl, which ...
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 selectively floated from quartz. Recovery …
Pyrophyllite Al 2 Si 4 O 10 (OH) 2 stands as a common phyllosilicate mineral frequently co-existing with minerals like quartz, mica, kaolin, epidote, talc, feldspar, muscovite, siderite, and rutile. It is characterized by alumino-silicate minerals and contains moderate to high silica and alumina. The high quality, pyrophyllite is desirable in the industry such as refractory, …

In this study, feldspar ore was successfully enriched using a two-stage process. Initially, dry magnetic separation was employed to remove iron oxide, followed by cationic flotation to eliminate gangue minerals containing free silica. A feed sample with a size fraction of (− 0.25 + 0.053) mm, pre-treated by attrition scrubbing and dry high-intensity magnetic separation …
Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores. Dry recovery …
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 fundamental studies seeking …
Common feldspar beneficiation processes Feldspar types. At present, the common feldspar beneficiation process mainly includes the following four types: 1. High-quality feldspar produced in ...
The beneficiation of feldspar from arkosic sandstone should take in consideration that the small size fraction (-500 µm) contain the highest amount of feldspar and that feldspar is friable and easily ground to small grains if it is subjected to grinding.
