Additionally, Ca(OH) 2 and CaO have a negative effect on bentonite's binding. This is due to the soluble calcium ions, which can displace sodium in bentonite and alter the surface charge. Though the effect may be negligible with calcium bentonites, sodium bentonites are strongly preferred as they result in higher strengths at …

Methods of Testing Bentonite Clays for Agglomerating Iron-Ore
One binder that is widely used in the production of iron-ore pellets is bentonite. The main mineral in bentonite – montmorillonite – has a unique ability to absorb water and undergoes a significant increase in volume. This phenomenon is called swelling . Study of the kinetics of swelling shows that this process is near completion after 24 h.

Commodity Description. Bentonite is a type of clay rock that is widely used in industrial processes and products and in consumer products. When wetted it holds water and swells significantly and, upon drying, it shrinks significantly. When mixed with sufficient water to create a slurry it forms materials that become more solid when compressed.

1. What is Bentonite? Bentonite, also referred to as "porphyry" or "bentonite," is a non-metallic mineral primarily composed of montmorillonite.It typically contains small amounts of illite, kaolinite, zeolite, feldspar, and calcite. The composition of montmorillonite determines the natural bentonite's properties and value.
