Bentonite is a type of clay that is commonly used in various industries due to its unique properties. It is formed from volcanic ash and is known for its ability to absorb water and expand to several times its original size. The bentonite industry involves the mining, processing, and distribution of bentonite clay for use in a variety of applications. Bentonite is primarily used as a binding agent in the production of iron ore pellets, foundry sands, and drilling muds. It is also used in the construction industry as a waterproofing agent and in the production of cement and ceramics. Additionally, bentonite is used in the agriculture industry as a soil conditioner and in the cosmetics industry as a thickener and emulsifier.
