Abstract
Natural zeolites are found at many points of the world in the form of minerals. As for Turkey, quite large volumes of zeolites reserves are available in the following regions: Ankara (Nallihan, Beypazari, Polatli etc.), Kutahya-Sa- phane, Manisa-Gordes, Manisa-Demirci, Izmir-Urla, Balikesir-Bigadic and Cappadocia. By means of the works carried out only at the field in Balikesir- Bigadic region, one of the detected reserves in Turkey, it was understood that an easily workable potential around 500 million ton is available. According to the very limited observations made until today, it is stated that the total reserve in our country may be around 500 billion ton. In these regions, the types of clinoptilolite, hoylandit, chabazite, analcime and erionite from the zeolite minerals exist. Zeolites are widely used in many sectors such as energy, environment, construction, detergent, chemistry, medicine, mining, agriculture and livestock. Zeolites also provide great benefits when they are used especially in agriculture and livestock for the purpose of preventing environmental pollution threatening human being. In this study, zeolite sample taken from Manisa-Gordes region was used. Following the processes of crushing and sieving, zeolite sample was subjected to chemical analyses according to their grain thickness, microscopic examination, the analyses of XRD and Technological Tests (ceramic pre-technological reviews, value of oil absorption, whiteness measurements, examination of the zeolite sample as cat litter, determination of bleaching capability, porosity values) and their ore characteristics were determined. After the analyses, ferrous oxide, biotite, quartz, muscovite, feldspar, chlorite, non-zeolite silicates and metamorphic rock fragments have been found. This zeolite mineral with high mineral purity has been suggested to clear off all impurities via ore preparation and enrichment methods.

They are used in the prevention of heavy metal pollution such as Pb, Cu, Zn, Cd and Hg, which pollute the environment via industrial wastes in solid, liquid, gas
Summary
Zeolite is a word meaning “Fusing Rock”. It earned this name because of its ability to explode and disintegrate when it is heated. Zeolite minerals are in an aluminosilicate structure which is comprised of connected tetrahedral AlO4 and SiO4 via sharing oxygen atoms and can grow infinitely as a three dimensional web. Their structure is similar to honey combs or cages and includes alterable cations and water. Clinoptilolite and heulandite are very similar in terms of their crystal structure and they cannot be distinguished from each other, even in X-Ray images Both zeolite minerals are formed in a layered structure, tectosilicate sub class and their oxygen atoms are covered by silica or aluminium ions.
