... a “huge” industry as pointed out in the above quote by Smith (1988) . This potential industry is based on the unique chemical and physical properties of natural zeolites (e.g. high cation-exchange capacities, cation selectivity, molecular sieving) and their widespread occurrence in sedimentary deposits...
