China's Major Bentonite Production Regions and Industry Development
Bentonite, a layered silicate clay mineral primarily composed of montmorillonite, owes its unique properties—including water absorption, swelling capacity, adsorption, and cation exchange—to its crystalline structure. Capable of expanding 15-30 times in volume upon water absorption, bentonite is hailed as the "universal stone" for its versatile applications across industries.
Core Applications of Bentonite
Foundry & Metallurgy: Used as a sand binder in foundry molds and iron ore pelletizing, enhancing production efficiency.
Petrochemicals: Serves as a suspending agent and lubricant in drilling fluids (8 tons consumed per oil well).
Environmental Protection: Adsorbent for wastewater treatment, air purification, and anti-seepage engineering.
Pet Economy: Bentonite cat砂 dominates global markets due to its absorption, clumping, and low-dust properties. Chinese hubs like Jianping (Liaoning) and Ningcheng (Inner Mongolia) produce millions of tons annually, exporting to the US, EU, Japan, and South Korea.
High-Value Products: Nano-grade montmorillonite for advanced materials and pharmaceuticals.
Agriculture & Daily Use: Feed additives, pesticide carriers, and desiccants (outperforming silica gel).
Major Production Hubs in China
China’s bentonite reserves span 24 provinces, with 10 regions holding over 100 million tons each: Guangxi, Xinjiang, Inner Mongolia, Jiangsu, Anhui, Hebei, Heilongjiang, Zhejiang, Shandong, and Liaoning.
Key Regions:
Jianping County, Liaoning
"China’s Bentonite Capital": 26.97 million tons proven reserves, 200+ million tons potential.
Specializes in cat砂 production, hosting industry leaders like Tianyuan Weiwang.
Operates smart production lines with 200,000-ton annual output, aiming to become the "Global Cat砂 Hub."
Ningcheng County, Inner Mongolia
Global cat砂 supplier: 16 million tons reserves, 2 billion tons potential.
Fully automated plants (e.g., Xingmei Tech) produce 600 tons daily, exporting 80% to 130+ countries via cross-border e-commerce.
Mingguang City, Anhui
Produces calcium/sodium bentonite for foundry and chemical industries (70% montmorillonite content, ≥75 whiteness).
Other Regions
Zhejiang and Guangxi face challenges with fragmented resources and low-tech processing.
