Feldspar
is a important raw material in the industry of glass, ceramic, fillers, and
welding electrodes. This paper aims to characterize and interpret the trends in
reserves, resources, mine production and export case of feldspar in the
Türkiye. With over 250 Mt of total resources, feldspar belongs to the crucial
industrial minerals of the Türkiye. With annual outputs of approximately 7.5–8
Mt of feldspars, the Türkiye ranks among the top European and world feldspar
producers. There are sodium feldspar reserves in ÇineYatağan-Milas and Uşak,
and sodium-potassium mixed feldspar reserves in Bilecik Söğüt,
Manisa-Demirci-Gördes and Kırşehir Massif. The feldspar raw materials are used
in the domestic glass and ceramic industries, while more than 85% is exported,
generally to Italy, Spain and Russia.
