Granite is a kind of tectonic rock formed by volcanic lava rising to the surface of the earth’s crust under considerable pressure. The magma does not eject from the ground, but slowly cools and solidifies underground. It is a kind of plutonic acid igneous rock and belongs to magmatic rock (igneous rock). Granite is mainly composed of quartz, feldspar and mica. The content of feldspar is 40% ~ 60%, and the content of quartz is 20% ~ 40%. Its color depends on the type and quantity of

Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 crystal structure composed of two silica tetrahedrons sandwiched with a layer of alumina octahedron. Due to the layered structure formed by montmorillonite crystal cells, there are some cations, such as Cu, Mg, Na, K, etc., and the interaction between these cations and montmorillonite crystal cells is very unstable and easy to be exchanged by other cations, Therefore, it has good ion exchange. Abroad, it has been applied in more

What is dolomiteDolomite is a carbonate mineral, including iron dolomite and manganese dolomite. Its crystal structure is like calcite and often presents rhombohedron. It will bubble slowly when it is cold and dilute hydrochloric acid. Some dolomites emit orange light under the irradiation of cathode rays. Dolomite is the main mineral component of dolomite and dolomitic limestone. Dolomite crystal belongs to the carbonate mineral of cubic system, and the pure one is white; Gray when containing iron; It is brown after weathering and has glassy luster. It

What is kaolin Kaolin is a common clay mineral in nature, is also a very important non-metallic mineral, because of white, also known as dolomite. Pure kaolin is white, fine, soft soil, with good plasticity, fire resistance, suspension, adsorption and other physical properties. Kaolin resources are abundant in the world, with a total amount of about 20.9 billion tons. High-quality kaolin resources are widely distributed in China, the United States, the United Kingdom, Brazil, India, Bulgaria, Australia, Russia and other countries. China’s kaolin mineral resources rank among

What is marble Marble, also known as marble, is the original rocks in the crust of the metamorphic rock formed under the action of high temperature and high pressure in the crust, the main component of marble is calcium carbonate, accounting for more than 50%, mainly composed of calcite, limestone, serpentine and dolomite. The mohs hardness of marble is between 2.5-5, there are many colors, usually have obvious patterns, generally contain impurities, mineral particles a lot. Relative to granite, marble physical properties are soft, has strong compressive

What is barite Barite is the most common mineral of barium, and its component is barium sulfate. Produced in low temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, often with galena, sphalerite, chalcopyrite, cinerar, etc. Barite deposits in Hunan, Guangxi, Qinghai and Jiangxi provinces of China are mostly giant hydrothermal single mineral veins. Barite can also be produced in sedimentary rocks, appearing as nodules, mostly in sedimentary manganese deposits and shallow sea muddy and sandy sedimentary rocks. In the residual clay overburden of weathered residual deposits,

What is limestoneLimestone is mainly composed of calcium carbonate (CaCO3). Lime and limestone are a large number of raw materials used in building materials and industry. Limestone can be directly processed into stone and fired into quicklime. Quicklime Cao absorbs moisture or adds water to become hydrated lime. The main component of hydrated lime is Ca (OH) 2, which can be called calcium hydroxide. Hydrated lime is prepared into lime slurry and lime paste, which can be used as coating material and brick and tile adhesive. Difference:

What is calcite?Calcite is a kind of calcium carbonate mineral, which is the most common in natural calcium carbonate. [1] Therefore, calcite is a widely distributed mineral. Calcite crystals have a variety of shapes, and their aggregates can be clusters of crystals, granular, massive, fibrous, bell emulsion, earthy and so on. Many square fragments can be obtained by knocking calcite, so it is called calcite.Calcite has various crystal shapes. The main mineral of limestone, marble and beautiful stalactite is calcite. Travertine can be deposited in spring water,

What is gypsumGypsum is a monoclinic mineral and a hydrate mainly composed of calcium sulfate (CaSO4). Gypsum is a widely used industrial and building material. It can be used for cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc.The microporous structure and heating dehydration of gypsum and its products make it have excellent sound insulation, heat insulation and fire resistance.Medical applications (not expanded)Food industry applicationAccording to the hygienic standard for the use of food additives in China, gypsum
