| Popis: | This paper presents results of investigations of the quality of the natural zeolite as well as the quality of particular particle size classes of the natural zeolite. The aim of the investigations was to determine if the different classes possess different qualitys. The starting material used in experiements was the natural zeolite from Zlatokop deposit (Vranjska Banja, Serbia).. The classes -0.2+0.8 mm; -0.8+0.6 mm; -0.6+0.4 mm; -0.4+0.1 mm were obtained by wet sieving of the natural zeolite. Grinding processes of the natural zeolite gave classes -0.3+0.63 mm; -0.63+0 mm; -0,43+0 mm. Chemical composition , mineralogical XRPD analysis and cation exchange capacity (CEC) were performed on the starting sample and the obtained particle size classes. It was determined that all particle size classes possess similar quality. The highest cation exchange capacity was observed in classes -0,043+0mm (166,5 meq/100g) and -0,063+0mm (158, 8 meq/100g).
