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
