Fluorite
Fluorite or fluorspar is the mineral form of calcium fluoride (CaF 2).The mineral may occur as massive (Fig. 1.15) or vein-type deposit, in association with metallic minerals forming a part of mineralization.The associated minerals include barite, calcite, quartz, galena, sphalerite, and pyrite (Fig. 1.16).The vein-type mineralization is of hydrothermal origin.

The fluorite deposits occur as veins, irregular, and lenticular in shape in the brecciated and disseminated zones. The vein deposits are dominant. The veins are 1–30 m thick and 30–1300 m long, with an exceptional 3000 m long deposit at Bor Undur. 60–70 m thick veins were observed at the Khongor and Bujgar deposits.

All About Fluorite – Uses, Properties, Color, and WorthrockandmineralplanetFluorite and Fluorspar: Mineral uses and propertiesWhat are the different types of fluorspar?Fluorspar, the name used for fluorite when it is sold as a bulk material or in processed form, is sold in three different grades (acid, ceramic, and metallurgical). Acid grade fluorspar is a high-purity material used by the chemical industry. It contains over 97% CaF 2 .Fluorite and Fluorspar: Mineral uses and properties
geology/minerals/fluorite.shtmlWhy is fluorite called fluorspar?Combining 'fluo-' due to its use as flux in iron smelting and '-spar' from spear stone, Agricola coined fluorspar 2. Today the mineral form of calcium fluoride (CaF 2) is better known as fluorite, though fluorspar remains common in mining and industry.

What is acid grade fluorspar?Acid grade fluorspar is a high-purity material used by the chemical industry. It contains over 97% CaF 2 . Most of the fluorspar consumed in the United States is acid grade even if it is used in lower grade applications.

By ERNEST F. BURCHARD.
Fluorspar, or fluorite, chemically calcium fluoride (CaF2), consists of calcium and fluorine in the proportions of 51.1 to 48.9. The mineral is only slightly harder than calcite and consequently crushes easily, but it may be distinguished from calcite by its failure to effervesce with dilute hydrochloric acid.
