- The feldspars are by far
the most abundant group of minerals and are found in igneous,
metamorphic and many sedimentary rocks. Felsdpars are framework
silicates where each silica tetrahedra share all corners with its four
neighbouring tetrahedra.
- There are two types of
feldspar:Soda peldspar(7 percent or higher Na2O) and Potash feldspar(8
percent or K2O).Feldspar- silica mixtures can occur naturally, such as
in sand deposits, or can be obtaied from flotation of mined and crushed
rock.
- Feldspar is a common raw
material int he production of ceramics.It is used for thermoluminescence
and optical dating in earth sciences and archaeology.It is an ingredient
in Bon Ami brand cleaner.It is used as a glazing material.
- In the flooring sector,
feldspar is the main constituent in the body composition. It is used as
a flux, lowering the vitrifying temperature of a ceramic body during
firing and forming a glassy phase. Surface tension pull the remaining
solid particles together, giving a densification of the ceramic
body.
- In tableware, feldspar
gives a good fusibility for a product without defects.In sanitaryware,
the use of feldspar within vitreous ceramic bodies is used to facilitate
the optimization process.
- Basically, the two
properties which make feldspars useful for downstream industries are
their alkali and alumina content. Feldspars play an important role as
fluxing agents in ceramics and glass applications, and are also used as
functional fillers in the paint, plastic, rubber and adhesive
industries.
- The initial production of
feldspar was from pegmatite bodies. Pegmatites are bodies of rock
commonly of granitic composition that consist mainly of unusually large
crystals or masses of quartz, feldspar, and mica. Pegmatites crystallize
during the last stages of injection of granitic magma.
- Feldspar is currently
produced as a by-product of mining mica from pegmatites and other rocks
associated with the Cherryville quartz monzonite rock (a type of
granitic rock) in Cleveland County. Until recently, feldspar was also
recovered from the Kings Mountain district in Cleveland and Gaston
counties as a by-product of mining spodumene (source of lithium) from
pegmatites.
- Feldspar is ground
to about 20 mesh for glassmaking and to 200 mesh or finer for most
ceramic and filler applications
- Glass, including
beverage containers and insulation for housing and building
construction, continued to be the leading end use of feldspar
- Feldspar
consumption has been gradually shifting from ceramics toward glass
markets. Another growing segment in the glass industry was solar
glass, used in the production of solar cells.
- Feldspar also
can be replaced in some of its end uses by clays, electric furnace
slag, feldspar-silica mixtures, pyrophyllite, spodumene, or talc
- World feldspar
consumption totalled 13.9 million tonnes and is growing on average 2%
per annum. Turkey is the leading exporter, accounting for 33% of all
exports by quantity, while Italy and the USA remain the leading
importers. In Asia production of feldspar is worth over US$180
million.
