Smectites from the Ishirini bentonite deposit (Libya) were analyzed for their oxygen and hydrogen isotopic ratios. Based on published isotopic fractionation data the results argue for a main meteoric water origin of the fluids responsible for the transformation of pyroclastic rocks to bentonite at temperature range from 30° to 90 °C.

Bentonite production process features ore mining, sodium activation – if required, drying, and milling. Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate. Through drying, bentonite natural moisture content of about 2535% is reduced.
Solutions to Water Containment Needs Bentonite Waterstops. Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Unlike traditional clay based waterstops, this one utilizes rubber as base material to form a controlled, moisture active sealant that means the bentonite waterstop will not expand to ...
The most important properties of bentonite for which it is employed in many different industries are the following: Water absorption and swelling A fundamental property of bentonite is to absorb water and expand. However, not all bentonites have the same absorption capacity.
