Vermiculite

Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is one of the safest, most unique minerals in the entire world. A hydrated Magnesium Aluminum Silicate, it is lightweight, inorganic (incombustible), compressible, highly absorbent, non-reactive (yet compatible in many chemical compositions as a functional filler), may have a high cation exchange capacity (surface chemistry may be modified).

Vermiculite is found in various parts of the world, but currently the major mines are located in South Africa, China, Brazil, Zimbabwe, and the United States.Large operating mines today in China are located in Hebei and Xinjiang. It is mined and refined using a variety of techniques and supplied commercially in a range of particle size grades of vermiculite concentrate (unexpanded).

The vermiculite ores from these mines are different forms of hydrated phlogopite or biotite mica which has the remarkable ability of being able to expand to many times its original volume when heated---a property known as exfoliation. Vermiculite mines are surface operations where ore is separated from other minerals, and then screened or classified into several basic particle sizes.
