Vermiculite production

Vermiculite, chemical formula M g × (H2O) [Mg3 × (AlSiO3O*0) (H2O)], is a magnesium water inclouded aluminum silicate secondary metamorphic minerals of layered structure. It likes mica in form, and usually come from weathered or hydrothermal alterated black (gold ) Mica. It will present a deflection shape after heat expansion and water loss, liking a leech pattern in form , so it gets the name vermiculite.
