Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world. The details given here relate to the deposits mined in the Palabora region of North-Eastern Transvaal. Palabora vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times its original volume when heated, a property known as exfoliation.

After being mined from open cast pits by drilling and blasting, flake-shaped particles of Palabora vermiculite are separated from the host rock by a process of crushing and air separation. Ore is blended from various parts of the mine in order to maintain a consistent and reliable product. The final concentrate is graded, ready for shipment all over the world.
