Global Montmorillonite Clay Supply, Demand and Key Producers, 2026-2032

The global Montmorillonite Clay market size is expected to reach $ 1783 million by 2032, rising at a market growth of 2.9% CAGR during the forecast period (2026-2032).

The name bentonite was first suggested in 1898 for clay hosted by the Benton Shale in Wyoming. It was initially described as clay formed by the alteration of volcanic ash, but the most widely used commercial definition is that bentonite is clay consisting essentially of smectite minerals (usually montmorillonite) regardless of occurrence or origin.

Most economic bentonite deposits are of Cretaceous age or younger and associated with marine shale and marl (Wyoming), calcareous sands and marls (Morocco), carbonaceous shales and coal (South Africa), sandstone and conglomerate (Australia), dacitic pyroclastics and tuffs (Milos), andesite (China) or rhyolite and obsidian/perlite (China and Mozambique).

Bentonite is characterised by exchangeable cations such as Ca2+, Mg2+, Na+ or Li+ which affect its designation and properties. For example, bentonite is typically described as either swelling or nonswelling bentonite. Swelling bentonite (also known as western bentonite) is sodium bentonite that swells in water and is generally used in its natural state. Non-swelling bentonite is calcium bentonite (also known as southern bentonite) that is used as mined, after treatment with soda ash to produce sodium-exchanged bentonite, or treated with acid to produce bleaching clay. Li-rich bentonite is known as hectorite and is commercially mined only in the US.

Natural bentonites occur in two main forms: Na-based and Ca-based. While Ca-bentonite is more common, Na-bentonite is a more effective binder. To boost the binding power of Ca-bentonite, it is subjected to a chemical reaction with soda ash to activate its outer and inner surfaces, which increases its ability to bind water.
