Biotite Mica Uses

Muscovite | Properties, Occurrence, Uses

Muscovite is a common mineral that belongs to the mica group. It is a silicate mineral that is characterized by its thin, sheet-like structure. Muscovite is composed of potassium (K), aluminum (Al), silicon (Si), and oxygen (O) atoms arranged in sheets, and it is known for its excellent cleavage, which allows it to be easily split into thin, flexible sheets.

Micas | Earth Sciences Museum | University of Waterloo

Biotite. Biotite mica Biotite mica can be easily identified by its dark brown to black colour that is a result of the high ferro-magnesium content of the mineral. It is a common rock forming mineral that is found in granite, syenite and other igneous rocks. It is also found in metamorphic rocks such as gneisses and schists.

Biotite

Uses. The high iron content, which imparts dark colors, rules out biotite from many industrial uses. However, because biotite is abundant in granitic rocks, pegmatites, and schists that are also associated with the more desirable muscovites, the mineral is important for exploration. Biotite is mica of little commercial value.
