What is calcite

作者: 點擊:1983 發(fā)布時間:2020-07-23

The name of dolomite sand comes from the fact that it is easy to split along it into small square fragments. In compendiumofmateriamedica, lishijin thought calcite "is like a massive anhydrite, which is calcified, and the wall is bright, and its name is calcite".

The color of calcite varies with the impurities contained therein, such as light yellow, light red, brown and black when iron and manganese are present, but usually white or colorless. Colorless and transparent calcite is also known as Icelandic stone. This calcite has a wonderful function, through which you can see the double image of the object. Therefore, Iceland stone is an important optical material. Calcite is the main mineral of limestone and marble, and has many uses in production and life. We know limestone can form caves, and stalactites and stalagmites in caves are actually made of calcite.

It usually contains Mn, Fe, Zn, Mg, Pb, Sr, Ba, Co, TR and other similar substitutes; When they reach a certain amount, they can form manganese calcite, calcite, calcite, magnesium and other variants. In addition, mechanical mixtures such as brucite, dolomite, iron hydroxide and oxides, sulfide and quartz are also common in the crystal.

Calcite has various crystal shapes. The main minerals of limestone, marble and beautiful stalactite are calcite. Limestones can be deposited in springs and are usually secondary minerals in igneous rocks. In the almond cavity of basalt flow, the fractures of sedimentary rocks are often filled with calcite to form fine veins, or through biological action, crust or rock form.

Calcite was found in limestone mountains. It is widely found in the tertiary and quaternary limestone and metamorphic rock deposits. Calcite is the ore-making of the earth, accounting for more than 40% of the total crust. Calcite shall be of no less than 200 types. Representative producers are China, Mexico, the United Kingdom, France, the United States and Germany. All the world is mine.

Calcite is divided into two parts: calcite and calcite and iceberg. Calcite in China is mainly distributed in Guangxi, Jiangxi and Hunan. Calcite in Guangxi is famous for its high whiteness and low acid insoluble substance in domestic market. Calcite is also found in the northeast of North China, but usually accompanied by dolomite.
