• Description:
  Information on the mining and processing of zeolites is reviewed. Composition, structure, and varieties of zeolite, including erionite (12510428), mordenite (12043742), natrolite (1318952), ferrierite (12173307), and phillipsite (12174184) are presented. Zeolite types are classified and occurrences are cited. Deposits and production rates in the United States are given, with more than 300 occurrences of 6 different types in 25 states. Mining locations and zeolite species are tabulated. Mining and processing operations are described. Commercial applications of natural zeolites include use in solar powered refrigerators, solar collectors, and filtering of radioactive isotopes from contaminated water. It is also used in producing pozzolanic cements, as a filler in paper, and in agricultural and chemical applications utilizing its properties of ion exchange, adsorption, molecular sieve, and siliceous composition for dehydration and rehydration. Animal toxicity studies are cited in which peritoneal mesotheliomas occur in mice after injection with erionite. Human health effects are evaluated, with pleural mesotheliomas found in erionite miners. Site visits are noted, with no worker exposures to airborne zeolite fibers found.
