Sodium Activated Bentonite Process
Calcium bentonite may be converted to sodium bentonite (termed sodium beneficiation or sodium activation) to exhibit many of sodium bentonites properties by an ion exchange process. In common usage, this means adding 5–10% of a soluble sodium salt such as sodium carbonate to wet bentonite, mixing well, and allowing time for the ion exchange

What is Bentonite: Sodium & Calcium and Montmorillonite
Sodium Bentonite has a high percentage of sodium in the crystal lattice. Sodium Bentonite is mainly used in industries, as liner material, binders, suspension agents, cement tiles, concrete, wall boards and water-proofing building materials. They are also used in alternative health as an external detoxifier of skin and foot or as a poultice.
Mining and processing | Bentonite
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 25-35% is reduced.
