METHOD OF PRODUCING SODIUM BENTONITE
The soda ash activation method is usually conducted by adding 2-4% of soda ash (percentage based on weight of bentonite) to water. Then, bentonite is added and mixed to allow ion exchange of sodium and calcium to convert Ca-bentonite to Na-bentonite and to increase swelling capacity.

Activation of Non-Swelling Bentonite
The naturally high-swelling materials have undergone only partial calcification and do not require soda-ash modification. The relatively unaltered 'grey' or 'blue' bentonites have undergone little or no calcification. The latter have the highest Na to Ca ratios, are non-swelling, and do not respond markedly to soda-ash additions.
