Calcite: Meaning, Properties and Powers - The Complete Guide
Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is widespread 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 classed as a carbonate and has a vitreous or glassy luster.

Precipitated Calcium Carbonate (PCC)
The calcite crystal can have several different macroscopic shapes. These depend on the conditions of production. The most economical way to get PCC at a paper mill requires a satellite facility. The starting material may consist of limestone, but this is usually calcined (heated to drive off CO 2) at the mine, producing burnt lime, CaO.
