Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.
The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water.

Production process:
The rice husks from various rice mills are collected and will be transported to the Rice husk processing plant. Unloading will be done pneumatically or with gravity flow and excavators to intermediate silos. Before entering the silos impurities are separated by means of a riddle screen. Afterwards the husks are ground and fed to storage silos. Combu ....etc

Bentonite is a moisture retaining clay used as an earth electrode back-fill to help lower soil resistivity. The Bentonite clay is a sodium activated montmorillonite which when mixed with water swells to many times its original volume. If underground power cables are required to run at maximum direct burial rating when installed in cable duct, then the cable duct should be filled with Bentonite mixture (100 parts of 10:1 Bentonite / water mix to 20 parts sand and 8 parts cement). The Bentonite mixture should be pumped into the cable duct so tot ....etc
