Abstract :
Bentonite mineral is widely used as additive raw or filling material in various sectors (ceramics, cosmetics, paint, textile, casting, construction, etc.). The effective and efficient use of bentonites in these sectors depends on their chemical components. In this study, a total of ninety-eight bentonite samples collected from twenty-three quarries located in different geographical regions of Turkey were analyzed by EDXRF to determine the major and minor element distributions of bentonite quarries. The mean concentrations of K2O, Na2O, MgO, Fe2O3, CaO, Al2O3, SiO2, MnO, P2O5, SO3 and TiO2 analyzed in all bentonite samples were found as 1.40%, 2.78%, 3.25%, 4.36%, 4.65%, 15.24%, 54.12%, 0.10%, 0.20%, 0.35% and 0.58%, respectively. The highest concentrations of SiO2, Fe2O3, K2O and SO3, and TiO2 were analyzed in samples collected from bentonite quarries located in Ordu, Çorum, Trabzon, and Çank?r? provinces, respectively. The bentonite quarries in Konya province have the highest concentrations of Al2O3, MgO, P2O5, and MnO, while the bentonite quarry in Trabzon province has the highest concentrations of Na2O and CaO.
