How To Remove Feldspars From Sand Production
Feldspars
Alkali feldspars weather to clays, forming important deposits of china clay or kaolin. In arid regions, however, alkali feldspars accumulate in the sand and gravel formed by mechanical breakdown of rock. A SANDSTONE formed from this sand with more than 25 percent feldspar grains is called an ARKOSE.

The mineralogy of sandstones: feldspar grains
Feldspars are also common in metamorphic rocks. As such, feldspar is an important (usually subordinate) component of most terrigenous clastics, reflected in its inclusion in QFL classification schemes. The two major groups of feldspar are potassium feldspars and plagioclases. All have low relief in plain polarized light (similar to quartz).
