Quality Control


The pure quality of our products has drawn clients from various parts of the world. As the mineral obtained from the mines is contaminated with numerous impurities, we conduct proper measures to ensure that the final product is pure and impurity free. After the extraction, quarrying and drying of Bentonite Minerals are carried out in order to remove the impurities.
