Vermiculite is a naturally occurring mineral that expands when heated. Expanded vermiculite has unique and versatile characteristics; it is lightweight, provides energy savings when used as insulation, it is non-combustible, highly absorbent, pH neutral, inert, non-reactive to all but.
Feasibility for Identifying Mineralogical and Geochemical Tracers for Vermiculite Ore Deposits: The Federal Bureau of Investigation (Fbi: 9781288710546: Books - Amazon.ca
The goal of this report is to determine if it is a reasonable assumption that a chemical or mineralogical characteristic of vermiculite ore can be used as a tracer to identify the source of vermiculite in consumer products. The goal is not to identify a specific tracer, but rather to determine if pursuit of a tracer might be successful.

Vermiculite proper is a layered micaceous mineral formed by the hydrothermal alteration of mica (Brindley and Brown, 1980, Harben and Bates, 1990). Palabora vermiculite is not pure vermiculite but rather a mixed-layer vermiculite-biotite (Schwellnus, 1938, Basset, 1961, Schoeman, 1989). It is a product of the hydration of phlogopite/biotite ...

Vermiculite is mined using open cast mining techniques where the ore is separated from other minerals and then screened or classified into several basic particle sizes. Every care is taken in mining operations to minimize the impact on the environment and to restore land to its natural condition when mining ends.
Vermiculite is a 2:1 clay, meaning it has two tetrahedral sheets for every one octahedral sheet. It is a limited-expansion clay with a medium shrink–swell capacity. Vermiculite has a high cation-exchange capacity (CEC) at 100–150 meq/100 g.
Vermiculite Insulation - h2> "Vermiculite ore from that mine did come into Canada, but all vermiculite-based products, in terms of insulation, are really only in about less than two per cent of Canadian homes," says Paul Glover, director general of the safe environments program.
• All vermiculite ores contain a range of other minerals that were formed along with the vermiculite in the rock. Vermiculite ores from some sources were even found to contain asbestos minerals but asbestos is not intrinsic to vermiculite and only a few ore bodies have been found to contain more than tiny trace amounts.

Vermiculite Ore. Palabora Vermiculite is a lamellar flake-like hydrated magnesium-iron-aluminium silicate. Geologically Palabora vermiculite arises from the weathering, over time, of phlogopite mica. During the weathering process alkalis present in the mica are leached and replaced with water.
Based on a production volume of 1 million tons (1.2 x 109 kg) of vermiculite ore mined and beneficiated in 1979 to produce 314 x 106 kg of crude vermiculite, approximately 802 x 103 kg were released into the air, 89,900 x 103 kg were released into water, and 2,490 x 103 kg were released as solid waste.
