Commercial Manufacture of Exfoliated Vermiculite
In 2005, South Africa was the top producer of vermiculite with about 40% world share followed by the USA and China, reports the British Geological Survey.
While some exfoliators focus on only a few of the possible applications, others can provide vermiculite products for all its applications. It is common for vermiculite exfoliators to exfoliate perlite also, as both are often sold together. For those who want to set up a new exfoliation process, it is possible to find expert consultants to advise in the design and construction of the desired facilities. Vermiculite exfoliators have an international trade association called The Vermiculite Association to represent the industry's interests and to exchange information. Many of its members also maintain memberships in The Perlite Institute.

“The cultivation of one set of faculties tends to the disuse of others. The loss of one faculty sharpens others; the blind are sensitive in touch. Has not the extreme cultivation of the commercial faculty permitted others as essential to national life, to be blighted by disease?”
—J. Ellen Foster (1840–1910)
“The great cry that rises from all our manufacturing cities, louder than the furnace blast, is all in very deed for this—that we manufacture everything there except men.”
—John Ruskin (1819–1900)
