Bentonite mine
A number of large opencast bentonite mines are operational in Milos, especially in the northeast part of the island. Bentonite may form when volcanic ash weathers over long periods of time in the presence of water. Its main component is montmorillonite which is a hydrated sodium calcium aluminium magnesium silicate hydroxide which may also contain potassium and iron. Bentonite is a highly absorbent form of clay which increases in size several times when coming into contact with water, forming a viscous hydrate. It is used in a variety of industries as a sealant, binding agent. It is used for pet-litter and also in paper-making where it may also be used for deinking during paper recycling.
