Bentonite clay is a very unique substance, formed primarily of Montmorillonite, which is an extremely flat crystal flake, that carries a relatively strong negative ionic charge. The negative charge is compensated for by adsorbing a cation (either Sodium or Calcium) to the interior of the molecule, this is what makes it either Sodium …

Imerys bentonite adds significant value to the pelletizing process and the quality of the final product. Bentonite is used in drilling and tunnelling fluids to lubricate and cool cutting tools, remove cuttings and help prevent blowouts. It is a common component in drilling mud used to curtail drilling fluid invasion due to its propensity to aid ...

The concentrate (the wet taconite powder) is rolled with clay inside large rotating cylinders. The cylinders cause the powder to roll into marble-sized balls. (This is like rolling wet, sticky snow into balls to make a snowman). The balls are then dried and heated until they are white hot. The balls become hard as they cool.
