calcium hydrated aluminosilicate of volcanic origin containing a minimum of 85 % of clinoptilolite and a maximum of 15 % of feldspar, micas and clays free of fibres and quartz
clinoptilolite - a zeolite mineral (...) It is a potassium rich variety of heulandite.
Clinoptilolite is not the most well known, but is one of the more useful natural zeolites. Clinoptilolite is used in many applications such as a chemical sieve, a gas absorber, a feed additive, a food additive, an odor control agent and as a water filter for municipal and residential drinking water and aquariums. Clinoptilolite is well suited for these applications due to its large amount of pore space, high resistance to extreme temperatures and chemically neutral basic structure. What might strike many as odd is the food and feed additives. Clinoptilolite has been used for several years now as an additive to feed for cows, pigs, horses and chickens. It absorbs toxins in the feed that are created by molds and microscopic parasites and has enhance food absorption by these animals. Similar uses in actual people food is being tested. Clinoptilolite can easily absorb ammonia and other toxic gases from air and water and thus can be used in filters, both for health reasons and for odor removal.
