Calcium bentonite, a naturally occurring clay, has seen a steady increase in production due to its diverse applications in industries such as construction, agriculture, and pharmaceuticals. The global market size for calcium bentonite is estimated to be USD 765 million in 2025, with an expected annual growth rate of approximately 5.4% during the 2025-2032 period . This growth is driven by the rising demand for eco-friendly and sustainable products, as calcium bentonite is widely used in environmental applications like water purification and waste treatment. The price of calcium bentonite is influenced by factors such as mining costs, transportation, and demand from various sectors. With the increasing demand and limited supply, prices are expected to rise moderately. Additionally, the expansion of industries in developing countries contributes to the upward trend in prices. However, advancements in mining technologies and the discovery of new reserves may help stabilize prices in the long term.
