2021-4-30  Calcite mineral forms rocks and has the chemical formula CaCO 3. It is extremely common and can be found in sedimentary, metamorphic, and igneous rocks all over the world. Some geologists consider it a "ubiquitous mineral," meaning it can be found anywhere. Calcite is the main component of limestone and marble.

Chemical Classification: Carbonate

Calcite - an overview ScienceDirect Topics

Calcite is a carbonate mineral CaCO 3 (Fig. 1.13), and the most stable polymorph of calcium carbonate (calcite, aragonite, and vaterite).The color is milky white due to transparency with a yellow tint. The luster is vitreous with a white streak. The specific gravity of the mineral is 2.71 g/cm 3.The calcite in purest form contains 56.03% CaO and 43.97% CO 2.

2021-6-1  Calcite characteristics: Calcite is a calcium carbonate mineral with a wide distribution. There are many kinds of crystal shapes, and many square pieces can be obtained by hitting calcite, hence the name calcite. This type of mineral has very high hardness and stable chemical properties, so it has a very high application value.

Calcite Mineral Uses and Properties

GeologyUsesFormationConstructionMechanismDietPropertiesSafetySignificanceCalcite is a rock-forming mineral with a chemical formula of CaCO3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a \"ubiquitous mineral\" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. These rocks are extremely common and make up a significant portion of Earth's crust. They serve as one of the largest carbon repositories on our planet.

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.
