| Physical and Chemical Properties | Attapulgite is a kind of hydrous and magnesium-rich silicate clay mineral with layered chain structure, which is named because it was first found in the concave and convex field in Georgia, USA. Monoclinic system, the crystal is rod-like, fiber-like, internal porous channel, surface multi-groove, outer surface and inner surface are developed, can let cations, water molecules and a certain size of organic molecules. The color may appear white, light gray, light green, or light brown depending on the impurities. Hardness 2~3, heated to 700~800 degrees C, hardness> 5. Density 2.05~2.30g/cm3. Eary gloss. Easy to float on the surface of the water. The lobes are flat and flexible. It has strong water absorption when dried. The blue absorption, colloid value and expansion capacity of attapulgite clay are lower than those of montmorillonite clay. The higher the content of attapulgite, the stronger the adsorption and decolorization ability. Cations may be exchanged. It has high plasticity in the case of water and good stability in high temperature and saline. In water does not swell or swelling is very small. It is formed by weathering of magnesium-containing volcanic rocks and limestone; It is also the product of lacustrine deposition, lacustrine Bay deposition and marine deposition, and is often mixed with montmorillonite sepiolite, dolomite and other components to form clay layers. |

凹凸棒石 - Use
Open Data Verified Data
attapulgite clay has been widely used in petroleum, chemical industry, building materials, paper making, medicine, agriculture and so on. In the building materials industry, attapulgite clay is used as a filler, leveling agent, thickener and stabilizer to replace the traditional light calcium. In light industry, it can be used for tanning, instead of soda, which not only reduces the cost, and the kneading time will be reduced; Paper industry can be used as paper filler and coating pigment, mainly for gravure printing, and can be used for offset printing, pigment, coated paper and coated paperboard; textile industry as a dye suspension filler, coating slurry, printing paste; Drilling industry used in geothermal drilling, oil drilling, offshore drilling and ultra-deep drilling, high slurry rate, good sealing, anti-saline, high temperature stability, can prevent the collapse of the well, protect the wall, reduce the waste well rate, and can reduce the cost of drilling. Attapulgite powder can also be used as an additive for mixed feed, a suspension agent and a carrier for pesticides, and can also be used for water treatment, washing aids, molecular sieve raw materials, desiccants, cosmetic raw materials, rubber fillers, etc.

| use | attapulgite clay ore uses attapulgite as the main mineral component. In the chemical industry, it is mainly used as a coagulation preventive agent for urea and granular fertilizers, a processing aid for rubber, a clay thixotropic thickener for polyester resin, a carrier for pesticides, a catalyst for diaminophenylmethane and dichloroethane, Plastic filler and foaming spirit decolorant, etc. It is also widely used in coatings, petroleum, casting, military, building materials, papermaking, medicine, printing, environmental protection and other departments. |
| production method | there are not many mining mines in our country at present, and the mining scale and output are not large. Most of them are open-pit mining with a low degree of mechanization. The commonly used beneficiation method is hand selection, and sometimes the screening method is used to remove some coarse impurities. The processing technology of attapulgite clay is roughly divided into four steps: extrusion, grinding, heat treatment, adding dispersant and surfactant. |
