Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Large crystals of mica used for various appliions are typically mined from granitic pegmatites. Scrap and flake mica is produced all over the world. The commercially important micas are muscovite and phlogopite, which are used in a variety of appliions.

Phlogopite, also called brown mica, basic aluminosilie of potassium, magnesium, and iron that is a member of the common mica group. Varieties that contain only small amounts of iron are economically important as electrical insulators. Phlogopite occurs typically as a metamorphic product (, in crystalline metamorphosed limestones) and also in ultramafic igneous rocks.

The most commercially important variants of mica are muscovite and phlogopite. Mica is mined in more than 35 countries. While there is competing and incomplete data on precise production volumes, due in part to the informal economy that is involved in mica mining in some countries, the consensus is that India and Madagascar are the two largest sources of mica followed by China and Brazil.

Phlogopite mica is more suitable than other types of mica for separating the segments of a commutator, because it wears more evenly and at about the same rate as the metal bars. Some of the highest grade phlogopite is found in Canada, in an area within 150 kilometres Ottawa, where large hexagonal crystals, none exceeding 30 centimetres in diameter, can be found.
