Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot (1774 - 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Biotite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.

In this paper we describe the AFM observation of muscovite and biotite cleavage planes and computer image processing, including the development of an image processing procedure. Fine atomic arrange- ment of potassium and basal oxygen observed on the mica cleavage plane and their surface distribution are also discussed. @o ~Si,AI 2.

Alternative In Mica - Biotite. Jul. 10, 2018. Compared to the more common muscovite, biotite is also one of the mica minerals, also a silicate mineral. Black mica is mainly produced in metamorphic rocks and also in other rocks such as granite. Black mica has a color ranging from black to brown, red or green, with a glassy luster.

Biotite is a mineral that's named after French physicist Jean Baptist who studied and researched about it for its optical properties. It is also known as Black Mica. It usually occurs in rust, golden brown, reddish brown, dark brown, and brown colors. It forms a lens shape when it becomes heated by the sun and outwardly expands.

Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. These micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.

Ethnopharmocological relevance: Biotite mica enriched with Fe(2+) ions are widely used as a major mineral ingredient in traditional pharmaceutical science of alchemy (Rasashastra). Abhrak bhasma (mica ash), a pharmaceutical product containing treated mica, is utilized, for example, in Ayurvedic treatments for ailments such as gastritis, renal disease, skin disease and mainly in rejuvenation ...

As a raw material, biotite mica is first made into masterbatch. Then it is produced into non-woven fabrics with some antibacterial materials. And these non-woven fabrics will eventually made into face masks. Biotite has the functions of deodorizing, antibacterial and far-infrared rays. Therefore, masks made of biotite can deodorize more than 99%.

Mica mining process, ... There are 37 different mica minerals. The most common include: purple lepidolite, black biotite, brown phlogopite and clear muscovite. ... After blasting, the ore is reduced in size with drop balls and loaded on the trucks with shovels for transport to the processing plant, where mica, quartz and feldspar are extracted. ...

Biotite, or black mica, has a high percentage of iron (up to about 25%), which causes its usual black color; it is also high in magnesia, and so is often called magnesia-iron mica. On account of its dark color and high percentage of iron, which lowers its insulating power, it …
