In Our Society: The Economic Importance of Fluorite. The name 'fluorite' comes from the Latin word 'fluere' that means "to flow.". Fluorite melts easily and is used as a flux in the smelting of metallic ores. A 'flux' is a material used to help remove impurities from ore as it is refined into metal.
The optical absorption spectra of yellow fl uorite crystals from hydrothermal barite–fl uorite veins of the Erzgebirge, eastern Germany, are characterized by a broad absorption band with a peak at 433 nm that shows a subtle vibronic structure. The optical absorption behavior of the crystals is attributed to the presence of O3 – centers in the …
Fluorite (calcium fluoride, CaF2) crystallizes in the isometric system and has a Mohs hardness of 4.0, a specific gravity of 3.18, and perfect, four-directional cleavage. It often occurs in hydrothermal veins and is a common gangue component of the sulfide ores of lead, zinc and silver. Today, seven million metric tons of fluorspar (the ...
The mineralogy of the deposits is relatively simple, with the main ore minerals being fluorite, barite and bastnäsite.The fluorite occurs typically as subhedral, coarse-grained aggregates in the fault zones, sometimes as fluorite masses with rare colour-banding, less frequently cubic, and octahedral or rhombdodecahedral shape ...

Large cabinet specimen of Fluorite with blue (unlike the photos), cubic crystals to 6mm. Good coverage. Fluorite - Large cabinet specimen of Fluorite with blue (unlike the photos), cubic crystals to 6mm.
Fluorite is a halide mineral crystallizing in a cubic habit. It is the mineral form of the compound calcium fluoride: (chemical formula: CaF2 ) and is composed primarily of the elements fluorine and calcium. Fluorite occurs in nearly every color, with the most common hue being a deep purple.
Fluorite primarily forms in areas with high geothermal activity, such as hydrothermal veins. Its formation process is a true chemical ballet underground. Picture mineral-rich waters flowing through underground fissures. As these waters cool, the minerals within them begin to crystallize. Among them, calcium fluoride organizes into …
Most Fluorite gemstones are from deeply colored stones, but they can also be cut from the less intense color forms. The most popular color for Fluorite is purple, and deep purple Fluorite can closely resemble Amethyst.Fluorite is often brightly fluorescent in ultraviolet light.In fact, the term fluorescence is derived from Fluorite. Due to the very low …
Fluorite strengthens and balances the etheric structure of the body – aligning it with light flows. It opens the mind to all possibilities and helps one to assimilate and process new information at a phenomenal rate. Fluorite is the crystal of "learning". It is of immense help to any type of student. Carry some Fluorite about in a pocket ...
3D modeling was undertaken to establish the morphology, volume, and spatial distribution of the fluorite orebody, and ore grade of Jbel Tirremi located in northeastern Morocco. The ore is hosted in the intensely fractured Jurassic carbonates. The mineralization is structurally controlled because it is primarily hosted in N–S- and …

The accessory minerals under study are indicative of the depocentre of the fluids which lies close to an unconformity but does not, however, deliver information on the source of the mineralizing fluids. The nearness to the potential source rock of the fluids can only concluded from the presence of cerite-(Ce) which formed prior to fluorite.

The only commercial production of fluorite in South Australia has been from very small vein deposits in the Olary region. Fluorite was produced for the steel and glassware industries from two deposits within 1 km of Plumbago homestead, 40 km north of Manna Hill. Over 580 t were mined during 1932–36, and 110 t in 1956–58.
