Sodium bentonite act as a strong binder in the production of iron ore concentrate pellets as it offers higher water plate absorption and superior thermal stability. Sodium bentonite in iron ore pelletizing provides high swelling & bonding properties, large surface area, compressive strength, high sheer, high water absorption and good dry strength.
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.

Sodium bentonite, with sodium cation prevalence (Na+) allows water to penetrate through the platelets, forcing them apart, thus leading to swelling. Conversely, calcium bentonite, with calcium cation prevalence (Ca2+), while getting hydrated in much the same way, due to its strong positive charge, has lower absorption properties, not permitting ...

Bentonite Production History. The first bentonite production, at $25 per ton, was in 1888 by William Taylor from a property near Rock Creek. From 1888 . through 1895, Taylor shipped 5,400 tons of bentonite from the quarry to buyers across the country. The price remained stable until 1896, when purchasers refused to pay more than $5 per ton.
achieved by the addition of sodium carbonate (soda ash), in the process replacing exchangeable Ca and Mg cations with sodium cations. If bentonite requires additional sodium, soda ash may be added as powder or a solution to bentonite drying pads, or added to bentonite in mixing and shearing equipment such as pan mills, paddle mixers or extruders.
The United States is one of the top producers of bentonite, with almost a one-third share of the world's production, followed by China and Greece. Most high-grade natural sodium bentonite is produced from the western United States in an area between the …
Bentonite and/or casein may be added to aid fermentation.
