  • Mining and processing Bentonite

    Bentonite is a raw material present in many countries and mined in open pit quarries. Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep.

    Bentonite Earth Resources

    Bentonite is a very plastic clay that shrinks (or swells) markedly in response to the removal (or addition) of water. There are three main types of bentonite: high swelling (sodium) low swelling (calcium) moderate swelling (intermediate sodium-calcium) bentonite. The sodium bentonites are the most useful because of their greater swelling capacity.
