Vermiculite is a hydrated laminar magnesium-aluminum-iron-silicate which resembles mica in appearance. When subjected to heat, due to the inter-laminar steam generation, it exfoliates or expands several times.

Vermiculite mined, cleaned and then screened or classified into several basic particle sizes. The bulk density of crude vermiculite or vermiculite concentrate is in the range of 640-1120 kg/cu m or 40-70 lb/cu ft.
