The General Assembly made fluorite the State Mineral in 1965, when flourspar mining was a multimillion- dollar-per-year industry in Illinois. Over the years, much more fluorite has been mined in Illinois than in any other state. The many uses for fluorite
The Magic of Rocks and Stones. Fluorite (Fluorospar or Fluor Spar) Written and compiled by - Patricia Jean Martin. Fluorite, a mineral that melts easily, derives its name from the Latin word "fluere" meaning "to flow" or "to flux" and refers to its use as a flux in the steel and aluminum smelting process.
Fluorite is a halide mineral that is soft and usually colorless but can be blue, purple, green, brown, or yellow. Some times several colors are present in the same crystal creating a striking affect. Some times several colors are present in the same crystal creating a striking affect.
Sedimentary rocks, the third general rock type, are the "bones" of Indiana. Sedimentary rocks are made from sediments, which are small fragments of rocks torn from preexisting hard rocks and transported into seas ancient and modern. Sedimentary rocks also grow where minerals form from water through chemical precipitation.
Fluorite is considered to be one of most popular minerals in the world among gem and mineral collectors, second only to quartz. It is often referred to as 'the most colorful mineral in the world' owing to its variety of brilliant colors. Fluorite was first described in 1530 and …
Fluorite is often brightly fluorescent in ultraviolet light. In fact, the term fluorescence is derived from Fluorite. Due to the very low hardness and perfect cleavage of Fluorite, special care must be taken to ensure it doesn't get scratched or chipped.
Green Fluorite – This color fluorite is a wonderful healing stone, green is the color of healing and growth and this stone will assist one with both of those things. It has a very high vibration and I would suggest having it in your healing toolkit.
what type of process was used to form fluorite. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
Mineral Type - Fluorite 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.
Calcite will fizz when dilute hydrochloric acid is placed on it. It may be fluorescent, phosphorescent, thermoluminescent and triboluminescent (see fluorite for definitions of these properties). Calcite is one of the most ubiquitous minerals, being an important rock forming mineral in sedimentary environments.
1.17 Some important structure types a) Rock salt (NaCl), zinc blende or sphalerite (ZnS), fluorite (CaF2), antifluorite (Na2O) These structures are considered together because they all have ccp/fcc anions and differ only in the positions of the cations.
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.

Fluorite, CaF 2, is the most common fluoride mineral and the main source of fluorine for commercial uses. Some fluorite minerals are known as 'fetid fluorite', because they give off a characteristic smell when crushed. There are suggestions that fluorine gas is responsible for the smell, but the exact cause of the odour has remained a mystery.
Minerals and Their Uses. ..., and rock types that are used to make products we use in our daily life. Aggregates Natural aggregates include sand, gravel, and crushed stone. Aggregates are composed of rock fragments that may be used in their natural state or after mechanical processing, such as crushing, washing, or sizing. ... Fluorite is used ...
Multicolor or rainbow fluorite brings a combination of energies to enhance flexibility, free thinking, and emotional brightness. It can bring enhanced protection in the areas enhanced by all combined types and is used to repair muddy or torn areas of the aura.
Fluorite. Fluorite is commercially named fluorspar composed of calcium fluoride (CaF 2).It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching.
Fluorite is a relatively soft stone, rating only 4 on the Mohs scale, so it is not very practical for some types of jewelry, though it is suitable for pendants, earrings and brooches. Purple or violet is the classic fluorite color, often rivaling amethyst for richness. Blue fluorite is …
When fluorite occurs as a cavity fill in carbonate rocks it is usually associated with calcite, dolomite, anhydrite, gypsum and sulfur. In hydrothermal vein deposits, fluorite may be found with calcite, dolomite, barite, galena, sphalerite, and even silver ores.
Fluorescent minerals: One of the most spectacular museum exhibits is a dark room filled with fluorescent rocks and minerals that are illuminated with ultraviolet light. They glow with an amazing array of vibrant colors - in sharp contrast to the color of the rocks under conditions of normal illumination.
Fluorite has three main types of industrial uses depending on its grade. Metallurgical grade fluorite is used in iron and steel production. Fluorite is used as a flux to lower melting points of molten metals and remove impurities such as phosphorus and sulfur.
Fluorite occurs in all types of hydrothermal deposits. It also forms as an accessory in igneous rocks, especially syenites and granite pegmatites. In Wisconsin, most fluorite localities are in the Wausau area, associated with the Wausau and Stettin plutons.
The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science. Mohs ...
