Occurrence of Fluorite and Useful Mineral Association Fluorite occurs in an accessory mineral in granite, granite pegmatites and syenites; around fumaroles; in carbonatites and alkaline intrusives. The mineral can also be found in low- to high-temperature hydrothermal veins and stratabound deposits.
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.
Association of fluorite with different rock types in diverse geological envi- ronments shows variable REE distribution pattern within fluorite which provide insight into the REE proportions in the ore forming fluids and it is of great sig-
Fluorite cleavage: Fluorite is the only common mineral with four directions of perfect cleavage. This perfect cleavage combined with the mineral's isometric crystal structure frequently cause it to cleave into perfect octahedrons as shown here.
The Difficult Metallurgy Problem. While many ores respond to the same general pattern of treatment, each ore is an individual problem. Such is the case of this fluorspar ore which is characterized by the presence of a portion of the fluorite in extremely close association with calcium carbonate and silica and containing appreciable clay.
Children: Purple fluorite works well with hyperactive children. Teenagers will benefit from its use as it will help them with any written homework or presentation. Teenagers will benefit from its use as it will help them with any written homework or presentation.
Fluorite Properties. Fluorite is made up of calcium fluoride and has a transparent or translucent appearance. Sometimes it can be a colorless crystal, but other times it can also be purple, blue, green, yellow, or pink, or other combinations of these colors.
This specimen contains calcite, quartz and fluorite with pyrite micro-crystals. The fluorite can be viewed when looking at what could be considered the bottom of the specimen, noted by its yellow hue, typical to specimens our of this area.
Fluorite Pierre : Semi précieuse Famille : Spath de fluor, Fluorure de calcium Énergie : Réceptive Planète : Mars Origine du nom : L'origine du mot fluorite vient du verbe latin fluere qui signifie « s'écouler » et de sa composition chimique riche en fluor.
British Columbia, Greenwood Mining Division, near Grand Forks, Rock Candy mine : Nice gold color, thick (2 cm) crystal, 4.5 cm, not very lustrous, perched with smaller barites at base on green, lustrous "pebbled" fluorite octahedral tops. 6x9 cm overall.
Fluoride is a mineral. In Canada, fluoride is found naturally in our water, air, food and soil. Fluoride varnish prevents tooth decay in people who are at risk for the disease. Fluoride varnish should be painted on your teeth by someone who has been trained to do so. Fluoride mouth rinses or
Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.
