Natural Zeolites Application as Sustainable Adsorbent for ...
natural zeolites are interesting materials to perform these processes. The selectivity of a sorbent depends on the ionic radius, cation charge, zeolite structure, distribution of active centers, and the temperature of the process (9). The efficiency of the sorption process depends on the pure zeolite content in a mineral,

Mineral processing characteristics of natural zeolites ...
The inferior grade of natural zeolite ores in comparison to their synthetic counterparts has been identified as a possible factor responsible for the relatively small market share of the former. This paper describes the results of laboratory-scale mineral processing trials carried out on relatively low-grade natural zeolite ores from the Aritayn Formation of northeast Jordan to improve their ...
