Googled a little. W.R Grace received hoppers of vermiculite from the Libby mines in Montana (until 1992), and later from a mine in South Carolina. It received vermiculite in hoppers carrying 45-50 tons each, and processed this by exfoliating it (heating it and letting it expand), turning it into various products - insulation, a lightweight aggregate for construction, soil addition for gardening, fireproofing, and absorbent and filtering uses in the industry.
