You cannot process uncompressed ores with less than 100 units of a single type, e.g. 75 units of Veldspar cannot be combined with 25 units of Dense Veldspar for processing. Both compressed and uncompressed ores yield the same amount of minerals per batch.

The ore contained asbestos. Records show that up to 10,317 tons of vermiculite ore was processed at the facility from January 1967 to October 1970.The site was an exfoliation facility that processed more than 100,000 tons of vermiculite ore from Libby mine. Exfoliation, a processing method in which ore is heated and popped, is expected to have released more asbestos than other processing methods. Phase 2 ATSDR will continue to evaluate former Libby vermiculite processing sites inDec 07, 2004 that either expand vermiculite or use expanded vermiculite as a product ingredient. Seven facilities were expansion plants that exfoliate the raw vermiculite ore. These plants then bag the exfoliated vermiculite for re-sale or use it as a product ingredient in a downstream process for example, the production of thermal insulating materials,

Processing of the ore can sometimes lead to the peeling off or scrolling of the surface layers at the edges of crystals forming fibres Chatfield and Lewis 1980.Vermiculite contaminated with Libby Amphibole asbestos was shipped to nearly 300 processing plants around the country. Upon delivery, the ore was exfoliated. Exfoliation is a process in which vermiculite ore is heated at high temperatures to expand or pop it.Vermiculite flake is the crude vermiculite ore, generally called unexpanded vermiculite. After mining from the quarry, the impurities are removed, the appearance is flaky, so it is called vermiculite flakes, also called raw vermiculite, raw vermiculite ore, crude vermiculite, unexpanded vermiculite, unframed vermiculite.The site was an exfoliation facility that processed more than 100,000 tons of vermiculite ore from the Libby mine. Exfoliation, a processing method in which ore is heated and popped, is expected to have released more asbestos than other processing methods.
