There are three important criteria in life, the production of food, the reduction of man made energy and the safety of human life. Mandoval Vermiculite plays a major role in all three. Going back over 45 years Mandoval Vermiculite was originally registered as a subsidiary of a well know mine in palabora, its purpose to establish markets for vermiculite. Vermiculite plays an important role throughout the economy particularly in the Agricultural, Energy, Mining, Manufacturing and Horticultural sectors. Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. Vermiculite is hydrated phlogopite mica, which has the remarkable ability to expand many times its original volume when heated, a process known as exfoliation.
