About Fluorspar


History And Its Properties

Fluorite derives from the Latin noun fluo, meaning a stream or flow of water. In verb form this was fluor or fluere, meaning to flow. The mineral is used as a flux in iron smelting to decrease the viscosity of slags. The melting point of calcium fluoride is 1676 K. The term flux comes from the Latin noun fluxus, a wash or current of water. The mineral fluorite was originally termed fluorospar and was first discussed in print in a 1530 work Bermannus, sive de re metallica dialogus [Bermannus; or a dialogue about the nature of metals], by Georgius Agricola, as a mineral noted for its usefulness as a flux.[5][6] Agricola, a German scientist with expertise inphilologymining, and metallurgy, named fluorspar as a Neo Latinization of the German Flussspat from Fluß (streamriver) and “Spat” (meaning a nonmetallic mineral akin to gypsum, spærstān, spear stone, referring to its crystalline projections).[7][8]

In 1852, fluorite gave its name to the phenomenon of fluorescence, which is prominent in fluorites from certain locations, due to certain impurities in the crystal. Fluorite also gave the name to its constitutive element fluorine. Presently, the word “fluorspar” is most commonly used for fluorite as the industrial and chemical commodity, while “fluorite” is used mineralogically and in most other senses.

Properties

Fluorspar is a commercial term for the mineral. fluorite (calcium fluoride, CaF2)Fluorite is an important industrial mineral composed of calcium and fluorine (CaF2). which, when pure, contains 51.1% Ca and 48.9% F. It is used in a wide variety of chemical, metallurgical and ceramic processes. Specimens with exceptional diaphaneity and color are cut into gems or used to make ornamental objects. 

Fluorite is deposited in veins by hydrothermal processes. In these rocks it often occurs as a gangue mineral associated with metallic ores. Fluorite is also found in the fractures and cavities of some limestones and dolomites. It is a very common rock-forming mineral found in many parts of the world. In the mining industry fluorite is often called “fluorspar.

 Grades & Applications

 There are three main grades – Acid, Metallurgical and Ceramic

Acid Grade Fluorspar 
Acid grade fluorspar is a high purity material used by the chemical industry. It contains over 97% CaF2. Most of the fluorspar consumed in the World is acid grade even if it is used in lower grade applications.Acid grade fluorspar is the primary industrial source of fluorine in the world. It is mainly used to manufacture the following products:

  • Hydrofluoric acid (HF) – HF is used in a diverse set of industries.
  • Approximately 60% of HF is used as a feedstock for manufacturing a host of fluorocarbons such as CFCs, HCFCs and HFCs. These fluorocarbons are primarily used as refrigerants in air conditioners and as foam blowing agents/propellants in the manufacture of polymers.
  • HF is also used as a catalyst in petroleum alkylation, as a cleaning and etching agent in the semiconductor industry, and in the pickling of stainless steel.
  • Aluminum fluoride and synthetic cryolite – These are both critical raw materials in the electrolytic extraction of aluminum.

Ceramic Grade Fluorspar 
Ceramic grade fluorspar contains between 85% and 96% CaF2. Much of this material is used in the manufacture of specialty glass, ceramics and enamelware. Fluorspar is used to make glazes and surface treatments that produce hard glossy surfaces, opalescent surfaces and a number of other appearances that make consumer glass objects more attractive or more durable. The non-stick cooking surface known as Teflon is made using fluorine derived from fluorite. 

Metallurgical Grade Fluorspar 
Metallurgical grade fluorspar contains between 60 and 85% CaF2. Much of this material is used in the production of iron, steel and other metals. Fluorspar can serve as a flux that removes impurities such as sulfur and phosphorous from molten metal and improves the fluidity of slag. Between 20 and 60 pounds of fluorspar is used for every ton of metal produced. In the United States many metal producers use fluorspar that exceeds metallurgical grade.
