Natural zeolites are versatile minerals with a range of applications due to their unique properties, such as ion exchange, adsorption, and molecular sieving. Natural zeolites have been increasingly used in various application areas such as industry, environmental protection, medicine, and agriculture. Mongolian Gobi region groundwater has high hardness, heavy metal pollution, and high salinity. This research studied the possibility of purifying the hardness and heavy metal-polluted water of the Gobi region by mechanochemical activation of natural zeolite. We mainly explored the effect of experimental conditions, such as rotation speed, ball diameter, milling duration as well as ball to powder ratio and ball filling ratio, on the activation of natural zeolites. Natural zeolite activation by the mechanochemical method was determined with minimal energy consumption and optimal conditions at rotation speeds of 100, 150, and 200 rpm, milling times of 3, 5, and 10 minutes, and ball sizes of 1, 3, 5 mm using a planetary ball mill. When carrying out absorption at the optimal mechanochemical value, standard hardness water was calculated from the measurement values of Ca+2 and Mg+2 in plant A, and batch absorption was performed for 30-1440 minutes and the mass of absorbent material was 1, 5 , 10 g, the hardness decreased as the mass of the absorbent material and the time of absorption increased. The initial Ca+2 ion concentration was 580-600 ppm, after 780 minutes it reached the standard content of 100 ppm, and after 1440 minutes it became 75 ppm, which was included in the drinking water standard. We explored the potential of mechanochemical activation as a viable method for enhancing the utility of natural zeolites in groundwater purification applications, contributing to more sustainable water management practices.
