I do not want to spend much time chronicling the early history of natural Zeolites. We all know about or we can read about this subject in several review papers, including some of my own, how Zeolites were discovered in 1756 by the Swedish mineralogist Cronstedt and how over the years several dozen distinct species have been identified and their crystal structures determined. We can review how in 1858, Eichhorn showed that these materials can exchange some of their constituent cat- ions for others; how in 1857, Damour demonstrated their hydration-dehydration properties; and how in 1925, Weigel and Steinhof separated gas molecules on the basis of size once the water had been removed from the Zeolites internal structure. In 1932, McBain, as many of you know, termed this phenomenon "molecular sieving", and we use this phrase still today. The fact is, however, that all of this work was carried out on large, millimeter-centimeter size crystals collected from basalts or trap rocks, in which Zeolites minerals are ubiquitous constituents in vugs and cavities. At that time, Zeolite minerals, while attractive to the eye and while adorning almost every mineral collection, never seemed to occur in sufficient purity or amount in the basalts to be of commercial concern, despite the growing interest in their adsorption, de-hydration, and cation-exchange capabilities. Barrer's monumental work in London (see, e.g., Barrer, 1938) and Samashima's in Tokyo (see, e.g., Samashima, 1929; Samashima and Hemmi, 1934; Samashima and Morita, 1935) on zeolite adsorption and molecular sieve phenomena was carried out on chabazite and other zeolite crystals from basalt vugs. Barrer soon realized that the rarity of chabazite and mordenite, or of any other Zeolite for that matter, precluded serious thought of developing industrial processes based on the natural materials. Hence, being a good chemist, he decided to synthesize them. His successful synthesis of chabazite and mordenite, the two natural Zeolites having the most attractive adsorption and molecular sieving properties, suggested that the Zeolite group of materials did indeed have commercial potential.

Editors' Note: This review was presented in large part by Dr. F. A. Mumpton, Chairman of the International Committee on Natural Zeolites, as the introductory lecture at the 4th FEZA Euro workshop on Zeolites held in Ischia, Naples, Italy, prior to Zeolite '97, the 5th International Conference on the Occurrence, Properties, and Utilization of Natural Zeolites. It also incorporates some of Dr. Mumpton's remarks to the full Conference regarding the future of natural research.

Linde's (Union Carbide) Involvement in Zeolite research

In the late 1940s, Linde Division of Union Carbide Corporation in Tonawanda, New York, got into the act. Because Linde's main business at the time was the cryogenic production of oxygen and nitrogen from air, they were constantly on the lookout for new and different ways of separating these gases from one another. Thus, Linde instituted a program of Zeolite synthesis under the direction of Robert M. Milton and Donald W. Breck specifically to produce chabazite for air separation and other adsorption/molecular sieve applications. Although the first few attempts were total failures (no chabazite was found), what was produced was a Zeolite, which was not known and which here to fore had no natural counterpart (Milton, 1959). This Zeolite we all know now is the famous Linde Zeolite A, which for many adsorption and molecular sieve purposes has properties even more desirable than those of chabazite. Zeolite A is, of course, a mainstay of the molecular sieve business the world over. [Milton and Breck, along with Edith M. Flanigen, were ultimately able to synthesize chabazite and mordenite and faujasite (synthetic Zeolites X and Y) and literally dozens of new Zeolites, having no natural counterparts (see Milton, 1968)

At the U.S. Geological Survey, he learned of Coombs' (1954) discovery of 300 feet of Laumontite-rich sedimentary rocks in New Zealand, and in Worcester he discussed with Sand the forthcoming paper by Ames, Sand, and Goldich on their recent find of high-purity clinoptilolite in tuffaceous sedimentary rocks near Hector, California (Amesetal., 1958). Linde suddenly realized that if LAUMONTITE and clinoptilolite occurred in deposits large enough and pure enough to be mined, there might indeed be a chance of finding natural deposits of A and X, as well as deposits of chabazite, erionite, and mordenite, the three natural Zeolites possessing adsorption properties similar to those of the synthetics.
