文摘
- •
A bentonite with 44% montmorillonite was purified adopting a simple method.
- •
Purified bentonite with montmorillonite content of 96.5% and montmorillonite yield of 70% was obtained.
- •
Appropriate grinding of raw bentonite and dispersant are very important for the centrifugal separation.
- •
Under the optimal condition, bentonite with different montmorillonite content and yield can be obtained by adjusting the centrifugal speed.
