Explanation

It is also called attapulgite clay. It is a kind of clay mainly composed of palygorskite. Its composition is generally complex, including sepiolite, montmorillonite, kaolinite, mica, quartze, opal, caldte, etc. Single ingredients and pure texture are relatively rare. palygorskite clay has two genetic types, one is hydrothermal type, the other is sedimentary type. The mineral particles are fine, and clay is often white, gray, gray green, earthy. It has a slippery feeling and is fragile. palygorskite clay has good plasticity and cohesiveness when wet, and good adsorption when dry. Its volume does not expand after adsorption. It has strong decolorization ability and bromine removal performance, and can remove toxins. It has good thixotropy and insulation properties, and good stability in high temperatures and saline water, making it an important non-metallic mineral raw material with a wide range of applications. It is widely used in various fields such as petroleum, chemical industry, construction, papermaking, medicine, agriculture, etc. Sedimentary palygorskite clay is of industrial value. Among the palygorskite clay minerals discovered in China, the deposits in Liuhe, Xuyi, Jiangsu and Jiashan, Anhui are large in scale and of good quality.
