2.Vermiculite production

Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance.  It is found in various parts of the world, vermiculite is basically a hydrated phlogopite mica which has the remarkable ability t expand to many times its original volume when heated at 850  °C.Vermiculite is most widely used in its exfoliated form.  The concertina-shaped granules of exfoliated vermiculite are non-combustible as well as being insoluble in water and all organic solvents.  Safe and easy to handle
