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.

Nov 27, 2016· The effect of bentonite on body function Detoxification. Bentonite clay has been shown to act as a detoxifying agent. This property is referred to its poly-cationic nature, which leads to absorption of negative charge toxins ().T-2 is a trichothecene mycotoxin which is a naturally occurring mold byproduct of Fusarium fungus and is toxic to humans and animals.
The present study shows the factorial design of the sodium activation for a polycationic bentonite from Quatro Barras, Paraná. The factors considered in the study were: reagent (NaOH and Na 2 CO 3), concentration (1% and 5%) and contact time (24 and 72 h). The response variables were swelling and cation exchange capacity.

Bentonite clay possesses excellent bleaching, binding, and healing properties. Bentonite contains more than 85% clay mineral called montmorillonite. Though there are many variations, calcium and sodium bentonite are the two major types. While sodium bentonite is the highly swelling type, calcium bentonite is the non-swelling type.
