Bentonite is an industrial mineral with a high content of swellable threelayer clay minerals, which often originates from the transformation of volcanic ashes and tuffs. Bentonite is used for the production of activated bentonite. The production volume of bentonite amounted to 12.04 million metric tons in 2013 (Virta 2015).

The term Bentonite was first used for a plastic clay found in about 1890 in upper cretaceous tuff near Fort Benton, Wyoming. The main constituent, which is the determinant factor in the clay’s properties, is the clay mineral montmorillonite. This in turn, derives its name from a deposit at Montmorillon, in Southern France.
