What is Vermiculite?
Vermiculite has been used in various industries for over 100 years and its occurrence as a natural mineral (hydrated phlogopite mica) dates back as far as 3.0 billion years old and it is one of the worlds’ most unique minerals. Some of the largest commercial mines in the world who are exclusive Vermiculite suppliers, are located in Southern Africa, Australia, China, Brazil and USA. Once the ore is mined and graded it is then subjected to a furnacing process which is also known as exfoliation. Exfoliation is a process where the ore is heated to approximately 800⁰C, at this point, water particles in the ore are boiled off and evaporated which then causes rapid expansion to form concertina Vermiculite particles.
Vermiculite is used for many expected and also many unexpected applications world wide. Exfoliators, suppliers of Premium Vermiculite have found their product is used in five main industries yet its use has seen rapid growth in many innovative applications.
