Bantonite is a clay mineral predominantly
consisting of the mineral Montmorillonite mixed with some related
minerals like Nontronite and Beidellite. These are three-layered
Aluminosilicates with molecules of water between layers. For natural
Sodium Bentonite, exchangeable sodium cations are predominant, rather
than other cations like calcium, magnesium etc. Similarly in Calcium
Bentonite, calcium cations are predominant. Bentonite is known as
“Bleaching Clay” due to high swelling property. Our products finds vast
uses in following areas :
- As a grouting material, having very low permeability of water.
- Used in drilling mud’s
- As a decolorize
- As a foundry sands.
- As a carrier in insecticides, paints and pharmaceutical industries.
- As a bleaching agent of vegetable oils and petroleum.
