【Abstract】 Using Ca-bentonite ore powder as the raw material, purify the bentonite through water sieve 3 times. During the second and third purification processes, Na-activate the material twice. After the technological process, the characteristic index of the Na-bentonite increased distinctly, and the montmorillonite content increased from 67.4% to 90.6%.更多还原
