| Abstract: | The purification of bentonite from three producing areas of Sichuan Santai, Guangxi Tiandong and Xiazijie of Xinjiang was studied, and the effect of two kinds of Na+-transformation and purification processes of gravity sedimentation and ultrasonic centrifugation were compared. The influence of centrifugal speed, centrifugation time and the amount of sodium reagent on Na+-transformation and purification of bentonite was explored, the physical and chemical properties of cation exchange capacity (CEC), swelling capacity, colloidal price, blue absorption capacity, X-ray fluorescence and X-ray diffractometer were used to analyze the ore, and the chemical composition and phase composition of the sample were analyzed. The results show that the ultrasonic centrifugation can improve the purification effect, and the physical and chemical properties of the purified product are greatly improved. |
