Open publisher page 0 citations

Abstract

A Ca-bentonite from Ezhou is taken as the object of the study.The wet processing technology of purification is carried out to enhance the grade from 75.43% up to reach 89.91% under the condition of using sodium hexametaphosphate 0.5% as dispersant and a slurry density of 25%.The optimum conditions and best industry conditions of Na-activation are confirmed by test.A high quality Na-bentonite is obtained with the d(001) value is 1.237 0nm,expansion multiple is 72mL/g and colloid index is 500mL/15g.
