sodium activation process of bentonite

Mining and processing Bentonite

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. Since bentonite is hygroscopic, this is a difficult process that has to be performed under controlled temperature, in order not to damage its molecular structure. As a

Calcium bentonite may be converted to sodium bentonite (termed sodium beneficiation or sodium activation) to exhibit many of sodium bentonite’s properties by a process known as “ion exchange” (patented in 1935 by Germans U Hofmann and K Endell). 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

Activation of Jordanian Bentonite by Hydrochloric Acid

During the acid activation process, the protons from the acid medium penetrated into the bentonite structure and attacked the OH groups, thereby causing alterations in the adsorption bands attributed to the OH vibration and octahedral cations, as mentioned earlier . Finally, following the activation process, most band positions did not change, thus suggesting that the basic bentonite structure did not collapse.

Mineral Notes: Bentonite • Snowden

Sodium and calcium bentonite may be treated (activated, or peptised) with soda ash to modify properties such as rheology, fluid loss, swelling index, water absorption and thermal durability. The addition of sodium carbonate (soda ash) replaces exchangeable Ca and Mg cations with Na cations. If bentonite requires additional sodium, soda ash may be added as powder or a solution to bentonite
