Definition of Bentonite

Bentonite, a clay mineral primarily composed of montmorillonite, is soft, porous, and highly absorbent. It forms from the weathering of volcanic ash and expands significantly when exposed to water. These unique properties make it indispensable across many industries. As a leading Bentonite Supplier, As your reliable Bentonite Supplier, we offer bentonite for various applications, including drilling, construction, animal feed, and cosmetics.

In the drilling industry, bentonite plays a critical role in stabilizing boreholes, removing cuttings, and cooling drill bits. In construction, bentonite acts as an effective waterproofing agent. Additionally, it supports digestion in animal feed. Moreover, its skin-cleansing properties make it a popular ingredient in cosmetics. Furthermore, bentonite is used in environmental remediation to contain contaminants in soil and water.

History and Origin

The use of bentonite dates back to ancient Egypt and Greece, where it was valued for its medicinal properties. By the 15th century, it was commonly used to treat skin and digestive ailments. The name “bentonite” comes from Fort Benton, Wyoming, where commercial extraction began in the late 19th century. Throughout the 20th century, its uses expanded into agriculture, cosmetics, and construction. During World War II, bentonite also served as a lubricant and bonding agent. Today, major bentonite deposits are found in the U.S., China, India, and Russia. As a result, industries worldwide rely on its versatile applications.

Bentonite Types

Sodium Bentonite

Sodium bentonite, which is known for its high swelling capacity, plays a key role in drilling mud by lubricating drill bits and carrying cuttings. It seals water and gas wells by preventing fluid flow through surrounding rock formations. Its binding, sealing, and clarifying properties also make it useful in foundry sands, waterproofing, wine production, and pet litter.

Calcium Bentonite

Calcium bentonite, though less swelling than sodium bentonite, finds use in foundry sands, water well sealants, and juice clarification. It is also popular in dietary supplements for detoxifying properties and in skincare for oil absorption and exfoliation. Major deposits exist in the U.S., Russia, and Australia.

Potassium Bentonite

Potassium bentonite is primarily used in animal feed to improve digestion and feed efficiency. It reduces feed consumption while increasing nutrient absorption. Additionally, it has a limited role in drilling mud and comes from deposits in Europe, particularly in Germany and France.

Magnesium Bentonite
