Hello friend, Natural Zeolite are hydrated aluminosilicates of the alkaline and alkaline-earth metals.Approximately 40 natural zeolites have been identified over the past 200 years, the most common of which are analcime, chabazite, clinoptilolite, erionite, ferrierite, heulandite, laumontite, mordenite, and phillipsite. Zeolites are commercially valuable because of their unique ion-exchange, molecular sieving, and catalytic properties. Commercial zeolite deposits in the United States are associated with the alteration of Producers of synthetic zeolites announced volcanic tuffs in saline, alkaline lake deposits plans to construct new plants and expand and open hydrologic systems. The deposits are existing plants and introduced several new located in Arizona, California, Idaho, Nevada, zeolites .Akzo Nobel began construction of a New Mexico, Oregon, Texas, Utah, and zeolite plant in Pasadena, TX and W. R. Grace Wyoming. The major components of these announced plans to build a zeolite plant in deposits are chabazite, clinoptilolite, mordenite, Louisiana that will supply catalysts to its and phillipsite. Erionite, orthoclase and fluidized cracking catalyst plant. with thanks Subhamoy Chatterjee India
