techniques for the beneficiation of the 500/74 µm fraction, in which the feldspar is naturally concentrated. Mineralogical and liberation studies The mineralogical studies showed that intergrown feldspar/quartz particles were practically absent in sizes smaller than 500 µm. A very low content of mica was also noted in the 500/74 µm fraction.

ALEX STREKEISEN-Alkali feldspar granite-

Alkali Feldspar Granite. Granite is a medium-tocoarse-grained acid igneous rock with essential quartz (>20%) and feldspar, where alkali feldspar constitutes between 100 and 35% of the feldspars, and minor mafic minerals. Hornblende and biotite are the commonest mafic minerals, however, muscovite is also frequently encountered.

Additional observations on the dissolution of alkali feldspars come from studies by Fenter et al. [100–102] and Teng et al. [103] of orthoclase dissolution on the (001) and (010) cleavage surfaces, which used atomic force microscopy and synchrotron X-ray reflectivity (Figure 7.3(a)).These studies found that the measured X-ray reflectivity did not decrease

Alkali feldspar granite - Wikipedia

Alkali feldspar granite, some varieties of which are called 'red granite', is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals.

In general, the extracted raw material is referred to as alkaline-feldspar granite, leucogranite, albitic granite or even feldspathite (alkali-feldspar syenite ). Feldspars make the major rock-forming mineral with reported predominance of albite (30–50%) over K-feldspar (20–30%); however, they can make over 75% in feldspathite varieties.

Certain differences between rhyolite and granite are noteworthy. Muscovite, a common mineral in granite, occurs very rarely and only as an alteration product in rhyolite. In most granites the alkali feldspar is a soda-poor microcline or microcline-perthite; in most rhyolites, however, it is sanidine, not infrequently rich in soda.
