Albite and microcline are the most important commercial feldspar but the products usually contain varying proportions of the other members of the system. 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.
Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.
