Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.

Calcite: Calcite, the most common form of natural calcium carbonate (CaCO3), a widely distributed mineral known for the beautiful development and great variety of its crystals.

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as “calcite”.

Calcite Group. Calcite-Rhodochrosite Series. A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties.

Calcite is common and abundant throughout the world. It has little intrinsic value since it is not scarce and is one of the most difficult minerals to cut.

Chemistry: CaCO3, Calcium Carbonate Class: Carbonates Group: Calcite Uses: In cements and mortars, production of lime, limestone is used in the steel industry; glass industry, ornamental stone, chemical and optical uses and as mineral specimens.
