Natural zeolites tend to be of low purity due to impurities such as minerals other than Si, Al, and quartz. Thus, natural zeolites are inappropriate for applications requiring highly pure zeolite, such as petroleum refining and petrochemical production. Table 2 summarizes the chemical compositions of commonly used natural zeolites .

Zeolites have a wide range of use, from construction industries, aquaculture industries, agriculture, space research to human and veterinary medicine. This broad application of natural and synthetic zeolites is given by their main properties: adsorption, molecular sieving and cation exchange capacity. In this chapter the main use of zeolites in veterinary medicine is reviewed.

The largest application segment for natural zeolites is construction, where it is predominantly used as a cement additive. The addition of zeolite in cement helps to produce a slower-hardening and stronger product. Other important applications of natural zeolite include, animal feed additive and nutrient release agent in soil conditioners.

Of this, 5,000 st were natural zeolites. In 1985, approximately 13,000 st of natural zeolites were mined in the United States. While synthetic zeolites have been used extensively in commercial applications, demand for natural zeolites has been limited. Their primary use is in areas where the use of synthetic zeolites would be uneconomical.

Applications. As we have pointed out above, natural zeolite has properties that facilitate its use in many applications. The particularity is that it carries out processes in a natural or ecological way, being able to substitute different synthetic chemicals by being able to perform the same processes but naturally and without creating chemical residues.
