It is a category of minerals of volcanic origin. Zeolites are aluminosilicates formed by the vitrification of volcanic ash over millions of years. They have a high porosity and a high ion exchange capacity.

Zeolites have many possible applications such as water filtration, plant culture medium, animal feed additive, moisture and odor adsorption, and gas separation. The Cubans called it “the magic rock” for its healing properties in animals and humans.

Natural zeolites are minerals, according to their chemical structure, all zeolites have a three-dimensional cage-like structure containing channels with a specific diameter. This crystalline lattice is made up of SiO 4 and AlO 4 tetrahedra in slightly different configurations for each type of zeolite. (For its rupture temperatures above 1300 degrees Celsius are needed).

This structure makes zeolites possess unique properties in nature that differentiate it from other aluminosilicates (kaolin, bentonite, clays, etc.)
