Fluorite is typically used in the production of hydrofluoric acid, which is used in various industries such as electroplating, stainless steel, refrigerating and plastic industries, in the production of aluminum fluoride, which is used in aluminum smelting, as a flux in ceramics and glass, in steel furnaces, emery wheels, optics, and welding rods. When found in nature fluorspar is known by its mineral name fluorite, and its typically a calcium fluoride. Fluorspar (Fluorite) is also found in a variety of geological environmental conditions. It can be found in granite (Igneous Rocks), it fills cracks and holes in sandstone, and it’s also found in large deposits in limestone (Sedimentary) rock. The term Fluorspar, when used as commodity name, is commonly known to also refer to calcium fluoride formed as a by product of industrial process.
Fluorspar is rather a soft type of mineral, which has a hardness of 4 on Moh’s Scale of Hardness. Pure fluorspar is considered to be colorless, but a variety of impurities are known for giving fluorite a rainbow of different colors by titanium. Including green, purple, yellow, pink brown, black and blue. The mineral it self has pronounced cleavage, which means it breaks on flat planes. Fluoride crystals can typically be well formed, beautiful, and highly priced by many collectors. Despite its beauty and physical properties, fluorspar is primarily valuable for its fluorine content.
Even though fluoride contains the element fluorine, its name derives from its very own chemical composition. This name was rather given by Georg Agricola in 1546 and was derived from the Latin verb fluere which means to flow because it melts quite easy. In many cases, spar is commonly establish as generic name used by mineralogists to refer to any non-metallic mineral that breaks easily to produce flat surfaces, in which has a glass luster. One of most common names that was used by miner’s along time ago was Blue John.
The United States had once produced large quantities of the mineral fluorspar, however, the great fluorspar mines of the Illinois-Kentucky fluoride district are now closed. To day, the United States is known for commonly importing fluorspar from China, South Africa, Mexico, and other countries around the world. A very small precentage of Fluorspar consumed in the United States is commonly derived as a by product of industrial processes. For instance, an estimated 5,000 to 8,000 tons of synthetic fluorspar is produced each year in the uranium enrichment process of refining of petroleum, and in treating stainless steel. Its also Hydrofluoric Acid (HF) and other fluorides that are recovered during the production of aluminum.
The majority of the United States annual consumption of fluorspar is for the production of hydrofluoric acid (HF) and aluminum fluoride (AIF3). HF is typically the key ingredient for the production of all organic and non-organic chemicals that contain the element fluorine. Its also used in the manufacturing of uranium. AIF3 is used in the production of aluminum. The remainder of the fluorspar consumption is as a flux in the making of steel, glass, enamel, and other products. A flux is typically a substance that lowers the melting temperature of a material that’s widely also used.
Some of the substitutes and alternatives sources is phosphoric acid plants, which process phosphate rock into the production of phosphoric acid, that’s produce as a by-product chemical called fluorosilicic acid. This is widely used to fluoridate public water supplies or to produce AIF3. Phosphate rich rocks are also a minor alternative source for elemental fluorine.
Fluoride is typically regarded as an attractive mineral that has wonderful protective and stabalizing influences. Its typically regarded as a wonderful type of healing crystal that’s available in an number of Fluoride Crystal Shapes and sizes. It may also be ground and harmonise body energy, and even turn chakras to create a stable soothing environment.
Crystals of fluoride are strongly known to be formed as cubes, and octahedra, and are often also twinned. Fluoride can also be formed in massive, granular, and compact habits. More so fluoride is strongly known to also occur in several different colors which can included colorless, purple, green, yellow, pink, red, white, blue or black. Its rather known as a transparent which forms in hydro-thermal veins and around hot springs. In several cases fluoride is known to be a very common mineral that's associated with quartz dolomite, calcite, pyrite, galena, sphalerite, barite, chalcopyrite, and various other hydro-thermal vein minerals. The best way in determining fluoride is by its fluorescents to light. Not mention fluoride is also an important industrial mineral which at one point was classified as fluorspar. In terms to its name fluoride is known to come from the Latin word fluere which means flow. Its rather known as reference to its use in iron smelting in order to improve fluidity of slags, and the refining of metals. Fluoride is also known to mainly occur as well formed crystals which the single crystals might have zones of different colors that follow the contour of the crystal face. In several cases fluoride is known to occur in cubes but can also rarely be formed in an octahedra which is less common. More so fluoride is also considered as the simplest anion of fluorine, which its salts and minerals are important chemical reagents, and industrial chemicals mainly used in the production of hydrogen fluoride for fluorocarbons. In several case fluorite is also present in water and can be found in many different types of food groups, and beverages.
In many cases, the violet colors of fluoride are known to also be produce by the combination of vacancy or even the structure it self can cause color. In many cases the colors of fluoride is known to be either formed by vacancy or its structural formation within that geological area and the presents of hydrocarbons. Other ways in determining fluoride is that it can be easily scratched by a knife compared to other minerals which have different hardness. Other formations of beryl can also occur within metamorphic and hydrothermal rock formations such as with Tennantite which is a copper iron arsenic sulfide.
In many cases, minerals that are fluorescents may occur, as its classified as an ability of some minerals to emit visible light of various colors. These colors such as in fluoride are considered to be formed by the contact of ultraviolet light known as black light. In addition to this, these types of fluorescence's were first discovered in 1824 by a German mineralogist known as Friedrich Mohs He also became a pronoun mineralogist who adapted his own scale which is called the Moh's Scale of Hardness. His observation had reported that some fluoride minerals were known to have appeared differently in color during night time hours than day time. These types of formations are known to occur when certain atoms within the structure moves into a different higher energy state when exposed to ultraviolet light.
Fluorides can also occur in a halide formation which is known to be formed when metals combine with one of the Halogen elements. These different types of elements can included a verities of minerals such as chlorine, fluorine, iodine, and bromine. In addition to this, there are also three different categories of halide groups which are identified as the simple halides, the halide complexes, and the oxyhydroxide halides. The crystallization of fluoride is also considered to consist of calcium ions which are coordinated with eight fluorine ions at the corners of the cube. The calcium within fluoride may also be replace by 20 of yttrium or cerium within the decomposition stage of one single radioactive. It can also be used in the making of artificial cryolite of refining aluminum, lead, and antimony. Its also the principal source of fluorine which is mainly considered to be used in the fluoridation of water, and in Teflon coating where its commonly known to help prevent the non-stick surface of Teflon cooking pans. For the most part fluoride is known to be mainly formed as a vein in which become also associated with silver and lead ores. More so fluoride is commonly known to also occur within pegmatite cavities, hot spring areas, and within sedimentary rocks. The mineral it self is considered to also be found in several parts of the world which includes Mexico, China, USA, Poland, Thailand, Peru, South American, Mongolia, Hungary, Czech Republic, and Canada.
The Structure of Fluorite CaF2, consists of Ca2+ ions arrange at the corners and faces of a cubic unit cell in which F Ions are tetrahedrally coordinated to four Ca2+, and each Ca2+ is coordinated to eight F at the corners of cube. This includes several oxides, such as uranium UO2, and Thorium ThO2, have fluorite type structures. Much of the space group of CaF2 is F4/m 3 2 m, with the crystal class being 4/m3 2/m.
