Take you to understand attapulgite clay

The attapulgite clay refers to a kind of natural non-metallic clay mineral with attapulgite as the main mineral component, belonging to the family of sepiolite mineralogy. The attapulgite clay is a crystalline hydrated magnesium aluminosilicate mineral. In 1862, the Russian scholar Long Kochinkov first discovered this mineral in hydrothermal alteration products in the Ural mining area and named it as a puddle. In 1935, the French scholar de Lapparent was discovered as attapulgite in the bleaching earth in the fort in Fort James, Georgia, United States. Later Huggins et al. demonstrated that the two clays have the same structure and belong to the same mineral. The attapulgite is in earthy, dense mass and is found in sedimentary rocks and weathered crusts. The color is white, grayish white, grayish gray, grayish green or weakly silky. The soil is delicate, oily and slippery, light in weight, brittle, strong in water absorption, and sticky and malleable in wet conditions. Since China first discovered attapulgite clay deposits in Liupanshan, Liuhe, Jiangsu Province in 1976, in 1982, large attapulgite ore deposits were discovered in Jiangsu and Anhui, Mingguang and other places. Due to the low level of development and utilization in our country, the application of this economically significant mineral deposit is limited to general fillers, and even exported to Germany and other countries in a cheap manner in the form of original soil, causing waste of resources. China's current research on this rare clay resource is limited to the general qualitative identification and morphology observation. The comprehensive study on it has not been reported. url:http://www.zhtworld.com
