Calcite in the form of limestone is used to make dog food. Sea organisms whose shells are made of calcite help balance the amount of CO2 in the ocean by absorbing it to make their calcite shells. Calcite is an example of a fluorescent mineral in that it can emit light when connected to a nonvisible UV light.

Jan 10, 2020· Calcite, calcium carbonate or CaCO 3, is so common that it''s considered a rockforming mineral. More carbon is held in calcite than anywhere else. (more below) Calcite is used to define hardness 3 in the Mohs scale of mineral hardness. Your fingernail is about hardness 2½, so you can''t scratch calcite.
Calcite is common and abundant throughout the world. The material has little intrinsic value since it is not scarce. However, calcite is one of the most difficult of all minerals to be cut because of perfect cleavage in 3 directions. The cost of faceted stone is therefore mostly in the labor of cutting.
