  • Bentonite Wikipedia

    Calcium bentonite may be converted to sodium bentonite (termed sodium beneficiation or sodium activation) to exhibit many of sodium bentonite's properties by an ion exchange process. As commonly practiced, 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 to take place and water to remove the

    Bentonite Activation MgO Soda Drilling mud This study explores, as an alternative to sodium bentonite, the possibility of (Na, Ca)-bentonites to meet the required drilling mud properties. Activation of the bentonites was performed using the most popular (Na 2CO 3) and also the most controversial additive (MgO) and their blends. Upgrading the (Na, Ca)-bentonites was elaborated on the basis of

    The bentonite used in greensand moulding is usually activated with sodium carbonate to achieve desirable properties. Activation of bentonite is known to improve mould related properties like giving a high wet tensile strength and improving the durability. The practice of activation is more common with calcium bentonite. A number 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 matter of

    Natural sodium bentonite is characterised by very high swelling ability, high liquid limit and low filter loss. This bentonite was used as the standard by which all other bentonites were measured for many years. The predominant exchangeable cation in natural sodium bentonite is the sodium cation but there may also be significant amounts of other cations present. Natural calcium bentonite

    Sodium-activated bentonite is produced by the addition of soluble sodium carbonate to calcium bentonite. This effects a base exchange on the surfaces of the clay particles, replacing calcium ions with those of sodium. The result is a bentonite exhibiting many of the typical characteristics of a natural sodium bentonite. Most bentonites used in civil engineering to produce support fluids are sodium-activated.
