| Abstract: | The raw material from Guangxi Binyang was used to prepare Na-bentonite by dry and semidry sodium-modified methods.The effects of sodium agent type,sodium agent dosage,bentonite moisture content and aging time on the modification effects were studied.Furthermore,X-ray diffraction （XRD） was adopted to characterize the performance of sodium-modified bentonite.The results show that dry sodium-modification can obtain sodium-modification bentonite for metallurgical pellet; and semidry sodiummodification can achieve an effective Sodium-modification bentonite with more excellent physicochemical properties,and its application field is wider. |
