About this site

Forms as an alteration product of biotite or phlogopite, by weathering or hydrothermal action.Vermiculite is mined as a natural insulation material. The best exfoliation properties were observed not for pure vermiculite, but for intergrowths of vermiculite and other layer silicates (e.g. hydrobiotite). Naturally expanded vermiculite can occur in volcanic rocks.

What is Vermiculite? - The Vermiculite Association

Vermiculite is mined using open cast mining techniques where the ore is separated from other minerals and then screened or classified into several basic particle sizes. Every care is taken in mining operations to minimize the impact on the environment and to restore land to its natural condition when mining ends.
