Fluorspar (also referred to as fluorite) is a mineral composed of calcium fluoride, CaF2. It is a naturally occurring mineral that tends to form in rocks that have been subjected to hydrothermal activity.


The main fluorite-containing mineral is fluorspar, CaF2. In its pure form it contains 51.5% calcium and 48.9% fluorine, and has a specific gravity of 3.18. The hardness is about 4. Commonly it is glassy, colorless, white, or grayish.

It can be also purple, pink, blue, green, or yellow. Fluorspar belongs to a cubic system mineralogically and crystallizes into cubic shapes in vugs and cavities. In most of the ore types it appears in massive forms, with interlocking crystals.


Fluorspar is used in many different processes throughout the chemical, ceramic and metallurgical industries, and is therefore split into three different grades: acid, ceramic and metallurgical.

Fluorspar (also called fluorite) is the mineral form of calcium fluoride, CaF2.

Industrially, fluorite is used as a flux for smelting, and in the production of glasses, electrodes, alloys, hydrofluoric acid and enamels.
