In order to improve the purity of bentonite, sodium polyacrylate, sodium pyrophosphate and sodium hexametaphosphate are used as dispersants to study the reagent influence on the dispersion behavior of bentonite ore. The yield and montmorillonite content influence are analyzed under different particle size conditions. The results show that under different dispersants conditions, the yield and the montmorillonite content at 70μm particle size are less affected; under different dosages of dispersant, those at -70μm particle size are less affected, while those at partial particle sizes are greatly affected.
