Calcite is a common mineral in many sedimentary rocks and metamorphic rocks. It is also present in soils, marine sediments and lakes and saline lakes. It is the main component of limestone. Calcite is a mineral from the carbonate family. It has a hexagonal crystal structure and is transparent to translucent. Its color varies from white to light gray, yellow, orange and even red. It has an average hardness of 3 on the Mohs scale. Calcite is mainly produced by biogenic and chemical processes. When waters move through limestone and interact with carbon dioxide, calcite is formed. It can also be formed by volcanic processes, fault movements or soluble processes. Calcite is widely used in the chemical, food, medicine and building materials industry. One of the main uses of calcite is to produce lime for road surfacing. Calcite is also used for the manufacture of ceramic products. In addition, it is sometimes used in optical systems for its optical properties.
