Bentonite is a montmorillonite-based hydrous clay mineral. The chemical composition of montmorillonite: (Al2, Mg3) Si4O10 OH2 · nH2O, because of its special nature. Such as swelling, cohesion, adsorption, catalytic, thixotropic, suspensible and cation exchangeability. It is widely used in various industrial fields.
Bentonite is a non-metallic mineral mainly composed of montmorillonite. The montmorillonite structure is a 2: 1 crystal structure composed of two layers of silicon oxynitride intercalated with an aluminum octahedron. Due to the formation of montmorillonite unit cells Of the layered structure of some cations, such as Cu, Mg, Na, K, etc., and these cations and montmorillonite unit cell role is very unstable, easy to be exchanged by other cations, it has good ion exchange. Abroad has been applied in more than 100 sectors in 24 fields of industrial and agricultural production, with more than 300 products, so people call it "universal earth."
Bentonite is also called bentonite, bentonite or bentonite. The development of the use of bentonite in China has a long history, originally just as a detergent. (Renshou area in Sichuan hundreds of years ago there are open-pit mines, locals call bentonite soil). Really widely used but only a hundred years history. The earliest discovery in the United States was that in the paleo-formations of Wyoming, there was a yellowish-green clay that was expanded into a paste when added to water. Later, clay was commonly referred to as bentonite. In fact, the main bentonite mineral composition is montmorillonite, content of 85-90%, some properties of bentonite are also determined by the montmorillonite. Montmorillonite can be various colors such as yellow-green, yellow-white, gray, white and so on. Can become a dense block, but also for the loose earth, rubbed with a finger when there is a sense of slippery, bulky small volume of water swelling several times to 20-30 times, was suspended in water, less water was a paste . The nature of montmorillonite is related to its chemical composition and internal structure.
The existing more than 100 bentonite mineral deposits are mainly concentrated in Xinjiang, Guangxi, Inner Mongolia and the three northeastern provinces. Among them, the reserves of bentonite in Xinjiang and the Autonomous County of Baksail have exceeded 2.3 billion tons and are the proven reserves The country's largest bentonite mining area. According to the Department of Geology and Mineral Resources in Xinjiang, there are 7 places of bentonite deposits in Inner Mongolia Autonomous County, including 4 large deposits (Wulangejer, Sun, Moon, Delun Shan and South of Delun Mountain). The mineral reserves of bentonite mine in Wulanyingge Mining Area is 572.8 million tons, of which 229.48 million tons of C-D bentonite ore are on the table and 2.80 million tons of off-balance-grade D grade ore account for 13.74% of the total bentonite reserves in China. . The mineral reserves of bentonite mine are 800 million tons in Sun & Moon mine area, 210 million tons and 0% respectively in south of Delun Shan and southwest of Delun Mountain. 800 million tons.
