| bentonite | bentonite, also known as bentonite, bentonite, is a kind of clay or clay rock with montmorillonite as the main mineral component. The name given by the American scholar W.C.Knight in 1898 when he studied the Cretaceous argillaceous rocks near Wyoming, USA. Bentonite is mainly composed of hydrous aluminosilicate minerals. In addition to the main mineral montmorillonite, it also often contains clay minerals such as illite, kaolinite, chlorite, halloyle, and beidite. The associated components include zeolite minerals and calcite, quartz, and feldspar, Glass debris, cuttings, etc. The main chemical components of bentonite are silica, aluminum oxide and water, magnesium oxide and iron oxide, as well as calcium, sodium, potassium, etc. Montmorillonite is an aqueous aluminosilicate containing a small amount of alkali and alkaline earth metal ions. The unit cell of montmorillonite is two silicon-oxygen tetrahedral layers with a hydrogen-oxygen octahedral layer. The cation heterovalent homoimage substitution makes it charge and has various characteristics such as adsorption and cation exchange. Bentonite can be divided into different properties according to the type of exchangeable cations and layer charge size of montmorillonite, such as sodium, calcium, magnesium, aluminum, etc., and each property can also transition from each other, that is, natural modification. People use this feature to artificially modify bentonite as needed in production. Fig. 1 is sodium calcium bentonite |
| classification | 1. according to color, it can be divided into gray-white, brown and variegated bentonite ore; 2, according to its properties and industrial uses, it can be divided into sodium-based, calcium-based and sodium-based bentonite ore. 3. bentonite can be divided into two categories according to water absorption. the first category can absorb a large amount of water and expand greatly after absorbing water. It is maintained in suspension in a thin water dispersant. This type of clay is mostly used as a plasticizer for ceramics. It can increase the drying strength and firing temperature of the porcelain blank and reduce the adsorption effect. The second type of bentonite can only adsorb slightly more water than ordinary plastic clay or bleaching soil, and its expansion is not significant, and it precipitates quickly in the thin water dispersant. This kind of bentonite is widely used as a clear clay, used in chemical, pharmaceutical, food decolorant, purifier, pesticide carrier and graphite crucible, enamel glaze regulator and binder, and the manufacture of construction clay products. |
| color | bentonite has milky white, white, light yellow, yellow, brown, pink, light green, light cyan, gray, etc. Usually, milky bentonite with a density of 2.4~2.8 is used, with a melting point of about 1 330~1 430 ℃ and extremely fine particles. It can adsorb water better than ordinary clay and play an alkali exchange role better than kaolin. After absorbing water, the volume increases to form a gel-like substance. It can adsorb water 5 times its weight, and its volume will expand 15 times. After adding water to form a colloidal solution, it can be suspended for a long time. After drying, water can be added to expand again, and repeated treatment does not affect its performance. In short, bentonite has the properties of water absorption, expansion, adhesion, suspension, plasticity and fire resistance. Information on the product characteristics, physical and chemical properties, classification, color, resource distribution, cause and composition, industrial use of non-metallic mineral bentonite is edited by Yao Yao. |
| Resource Distribution | The world's bentonite resources are mainly distributed in (1) Canada, the United States, Mexico, Peru, Japan, South Korea, the southeast coastal areas of China and the Philippines in the Pacific Rim metallogenic belt; (2) Spain, France, Italy, Greece, Turkey, Turkmenistan, Uzbekistan, Kyrgyzstan, Tajikistan, Kazakhstan, Xinjiang, Gansu and other places in the Mediterranean metallogenic belt; (3) India, Pakistan, Iran, Iraq, Sudan, Tanzania, Mozambique, South Africa, Myanmar, Indonesia and western Australia in the metallogenic belt around the Indian Ocean. Among them, Wyoming, South Dakota, North Dakota, Montana, Sardinia, Italy, Milos, Greece, Turkmen Ogranre, Askan, Georgia, Suri Fienhe, Armenia and Gujarat, India, are all world-famous bentonite deposits. Wyoming and South Dakota are the main producing areas of sodium bentonite. China's bentonite deposits are mainly distributed in Heilongjiang, Jilin, Liaoning, Jiangsu, Zhejiang, Shandong, Fujian, Guangdong, Guangxi and other provinces. Xinjiang, Gansu, Shaanxi, Jiangxi, Sichuan, Henan, Anhui and other places also have large-scale high-quality bentonite deposits. Among them, the bentonite resources in the three northeastern provinces (especially Jilin Province) and Guangxi are not only large in reserves and excellent in quality, but also mainly sodium bentonite, which is an important bentonite producing area in China. They mainly occur in the Jurassic and Tertiary coal-bearing rock series. |
| genesis and composition | bentonite has different genesis and composition, resulting in changeable ore color, complex structure and different structure. the quality of bentonite mainly depends on the content, properties and beneficial and harmful components of montmorillonite. Because of its good physical and chemical properties such as adhesion, adsorption, catalysis, suspension, dispersion, thixotropic and cation exchange, bentonite is often used in industry as binder, adsorbent, absorbent, filler, catalyst, thixotropic agent, flocculant, detergent, stabilizer, thickener, etc., widely used in metallurgical pellets, casting sand, drilling mud, grease decolorization, chemical industry, papermaking, rubber, medicine, agriculture and forestry and other industries. fig. 2 is a reference index for bentonite quality. the genesis of bentonite can be divided into three categories: weathering residue type, sedimentary-diagenetic type and hydrothermal alteration type. Bentonite occurs in the Jurassic, Cretaceous and Tertiary strata of the Middle and Cenozoic, and a few are produced in the Carboniferous to Permian strata of the Paleozoic. |
| industrial use | bentonite is mainly used as thickener and anti-precipitation agent for coatings and inks in industry. (1) bentonite is used as binder to form iron pellets, which are directly put into blast furnace for smelting instead of sintering method, which can save 10% ~ 15% of flux and coke and improve blast furnace production capacity by 40% ~ 50%. (2) drilling mud prepared with sodium bentonite has high pulping rate and many other advantages, and is suitable for oil drilling, high pressure jet wells, small diameter drilling and unstable formation drilling. (3) using sodium bentonite as casting sand binder can strengthen the sand resistance and solve the problem of sand collapse. (4) bentonite can be used as pesticide carrier and diluent, oil and oil purification and decolorizing agent, wine and sugar industry clarifier and purifier. In the past ten years, many new uses of bentonite have been developed. in coal mine production, the roadway excavated in bentonite is easy to expand and deforms or even blocks the roadway, which is not easy to support. |

It can effectively adsorb proteins, pigments and positively charged colloidal ions to produce condensation. When in use, add 10 times the amount of water to make it fully swell, stir into a slurry and add it to the juice to be treated, stir and disperse evenly, and filter after 0.5~1.0h. Bentonite can be used as a binder, adsorbent, filler, thixotropic agent, flocculant, detergent, stabilizer, thickener, etc., used as a carrier for fertilizers, fungicides and pesticides, rubber and plastic fillers, anti-settling additives for synthetic resins and inks, thixotropic and thickening of pigments and puree coatings, additives for daily chemicals, sorbents and adhesives for medicine, etc, it is also widely used in petroleum, metallurgy, casting, machinery, ceramics, construction, light industry, paper making, textile and food sectors. Used as emulsifier and adsorbent for proteins and particles in biochemical research, oil emulsifier. decolorant. |
| production methods | mining methods include open-pit mining and underground mining, mainly open-pit mining. Open-pit mining process: The main mining methods for underground mining are the room column method, the empty field method and the layered caving method, and the process is: the beneficiation method is generally selected directly by hand during mining. It is made by mining, crushing, grinding and drying. |
