Feldspar
Feldspar-rich rocks are used as an aggregate. Clay deposits are derived primarily from feldspar-rich rocks. Feldspars are raw materials for glass and ceramic industries. Ca-rich plagioclase feldspar has some potential as an aluminum ore, but currently it is more economical to extract aluminum from bauxite. They are also used in metallurgy.

Feldspar | Formula, Properties & Application
Feldspar can be found in all types of rock formations, including sedimentary, metamorphic, and igneous rocks. Its genesis involves a process known as "fractional crystallization," a procedure of slow cooling magma, where different minerals crystallize out of the melt at different temperatures. It also frequently appears in the form of veins ...
