Fluorite, also known as fluorspar, is the mineral form of calcium and fluorine (calcium fluoride or CaF 2).It is an industrial mineral used in the manufacture of chemicals, ceramic, and metallurgical processes. Fluorites with exceptional color and diaphaneity are used to decorate ornaments.

The apparent consumption of fluorspar (excluding fluorspar equivalents of fluorosilicic acid, hydrofluoric acid, and cryolite) in the United States was 601,000 metric tons in 2000 and was estimated to be 636,000 metric tons in 2001 (USGS 2002a). Approximately 60–65% of the fluorspar consumed goes into the production of hydrogen fluoride. Large

The TFE must be synthesized out of chloroform (trichloromethane), hydrofluoric acid, and fluorspar. These ingredients are combined in a process known as pyrolysis. TFE is highly flammable and its transportation is very risky. Therefore, this step must be performed on-site where the final product (PTFE) is created.

Fluorspar, also known as fluorite (CaF 2), is commercially important in metallurgical (e.g. used as slag viscosity modifier), ceramic (e.g. used to manufacture glass), and chemical industries (e.g. production of commercial HF).In the present study, a process has been developed to produce a ceramic grade fluorspar by-product from a rare earth element (REE)-bearing carbonatite deposit.
