Feldspar is one of the most abundant minerals in the earth's crust. Historically feldspar in Virginia was mined for use in the ceramics industry for abrasives and for gemstones (amazonite) (Pegau 1932). . Prior to about 1907 feldspar was mined primarily as a by-product of mica mining. Where can feldspar be found in the United States?

Mica ores are usually found in pegmatites associated with quartz, feldspar, tourmaline, apatite, spodumene, beryl, kaolinite and limonite minerals. Scrap and flake mica used to produce ground mica are usually recovered using crushing, screening and gravity methods, and when flotation is used, the mica ore must be deslimed typically at 100 mesh.

Mica deposits are either mined for mica only, when matrix yield is high enough, or in association with other minerals such as kaolin/feldspar. When Mica is present in soft rock, it is beneficiated through wet processing, typically blunging, gravity separation and flotation. Mica is subsequently dried to attain a moisture content below 1%.

The word mica is derived from the Latin word mica, meaning a crumb, and probably influenced by micare, to glitter. The name feldspar derives from the German Feldspat, a compound of the words Feld, "field", and Spat, "a rock that does not contain ore". The change from Spat to -spar was influenced by the English word "spar", a synonym for "mineral".
