The flake mica produced in the US comes from several sources: the metamorphic rock called schist as a byproduct of processing feldspar and kaolin resources, from placer deposits, and from pegmatit It is mined by conventional openpit methods In soft residual material, dozers, shovels, scrapers and frontend loaders are used in the mining.
Orthoclase feldspar (KAlSi 3 O 8), also called potassium feldspar or Kspar, is made of silica, aluminum, and potassium. Quartz and orthoclase feldspar are felsic minerals . Felsic is the compositional term applied to continental igneous minerals and rocks that contain an abundance of silica.

Nowbaran rocks are characterized by absence of feldspars coupled with abundance of clinopyroxene and olivine plus nepheline, melilite and other rarer phases. All the rocks show extremely low SiO 2 (– wt%), very high CaO (– wt%) and low Al 2 O 3 (– wt%), leading to ultracalcic compositions ( CaO/Al 2 O 3 > 1).
