Bentonite is used in making drilling agents. It improves their viscosity effectiveness which decreases filtrate loss and thickness of the filter cake. Due to this, the process of extracting drill cuttings out of the hole improves, pressure in the hole becomes steady and the drilling device gets cold and lubricated.

Used for nodulizing iron-ore concentrate when making pellets. Bentonite clays absorb excessive moisture and lubricate nodulized charge mixture. Bentonites are used as a binder to make mouldings, core sands and anti-penetration washes in foundries.

Used as a waterproof material: waterproof displays, mats, gaskets, to reinforce concrete trench walls and to increase bearing capacity of sand. Used as an additive to improve cement and its derivative qualities. In bloating clay production, bentonites are used as an additive in order to increase raw clay swelling. Bentonite can also be used as a tile softening agent.
