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.

What is Feldspar? "Feldspar" is the name of a large group of rock-forming silicate minerals that make up over 50% of Earth's crust. [1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar …

Rock phosphate is found in all continents of the world (figure 1). It is used as a raw material in the manufacture of inorganic phosphorus fertilizers and can be used as organic phosphorus fertilizers when applied directly to the soil. Direct application of rock phosphate increases crop yield and soil phosphorus levels (1, 2,3).

We are among leading suppliers of Feldspar. Feldspars crystallize from magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rock.

Feldspar. Feldspars are anhydrous three-dimensional aluminosilicates of linked SiO4 and AlO4 tetrahedra that contain cavities that can hold Ca2+, Na+, K+, or Ba2+ to maintain electroneutrality (Huang, 1989). From: Environmental Soil Chemistry (Second Edition), 2003. Download as PDF.
