Some bentonites were formed when volcanic ash deposits were altered in place by hydrothermal ground water. Most bentonite found in the US is of the high swelling, sodium-containing type, also known as Western or Wyoming bentonite. Deposits of low swelling, calcium-containing type, also known as Southern bentonite, are commonly found in …

The practice of activation is more common with calcium bentonite. A number of bentonite deposits tend to remain unbeneficiated due to their low cation exchange capacity (CEC) which are regarded as low quality commercial grade. The primary characteristic that shows the increased activation is the swelling index of the bentonite.
