Natural Zeolites: Processing, Present and Possible Applications

In order to select industrial fields in which natural zeolites can find massive and profitable utilization both for the economical and for the technical aspects, after a mention of the methods for evaluating the zeolite content and the beneficiation of the rock, the applications that are already effective and those not yet thoroughly investigated are reviewed. Some fields of application worthy of a preliminary, proper experimental research are moreover indicated. For these fields, which in case of success could open large market areas to natural zeolites, or to their mixtures with traditional products, the utility of an experimental investigation is also outlined in terms of the industrial importance of the problem.
