Biotite Water Treatment and Filtration - Power Organics

Biotite is a liquid concentrate that comes from a naturally occurring crystalline mineral compound called biotite. Biotite deposits are found in many places on the surface of the Earth. When biotite, produced by volcanic eruptions, comes in contact with seawater, it produces acids which structure and purify water.

Biotite Mineral | Uses and Properties

What is Biotite? 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.
