To the north the ore deposits are mainly found around the communities of Rosiclare, Elizabethtown, and Cave in Rock, in Hardin and Pope Counties, Illinois; it was in Shawneetown in 1818 that the first recorded discovery of fluorite was made.
After 1950 a tremendous influx of inexpensive foreign fluorspar sharply curtailed domestic production in subsequent years the progressive loss of the steel, aluminum, and chemical markets to overseas firms put to rest an industry that had vigorously led the world in production.

 Mineral Information Institute - FLUORSPAR - Fluroite
Fluorite (fluorspar): Used in production of hydrofluoric acid, which is used in the electroplating, stainless steel, refrigerant, and plastics industries, in production of aluminum fluoride, which is used in aluminum smelting, as a flux in ceramics and glass, in steel furnaces, and in emery wheels, optics, and welding rods.
Fluorspar is found in granite (igneous rock), it fills cracks and holes in sandstone, and it is found in large deposits in limestone (sedimentary rock).
For instance, an estimated 5,000 to 8,000 tons of synthetic fluorspar is produced each year in the uranium enrichment process, the refining of petroleum, and in treating stainless steel.

 Fluorspar Mining   (Site not responding. Last check: )
Fluorspar became a very important industrial mineral during the latter part of the 19th century when the steel industry found it to be a very effective fluxing material in steel smelting.
To meet the increasing demand for fluorspar by the steel industry, concentrating plants were built to refine the ore. Specifications set by the industry required that the fluorspar be in gravel form, assay no less than 85% calcium fluoride and silica not to exceed 5%.
During a period of certain temperature and pressure conditions, a chemical reaction took place between the gases and the rock walls of the fissures, and the minerals were deposited in veins and as replacements of the limestone beds.

Another major application for fluorspar is in aluminium manufacture, which will continue to grow in response to increased output of aluminium, although growth will be limited in response to a decline in unit use, driven by improved smelting technology, increased recycling of fluorine and some substitution by AlF3 derived from fluosilic acid.
Acid-grade fluorspar prices were low throughout the 1990s as a result of the rapid decrease in world demand coupled with a surge in exports of low-price concentrates from China.
