Less common are pink, red, white, brown, and black. As an infrared optical material, calcium fluoride is widely available and was sometimes known by the Eastman Kodak trademarked name "Irtran-3", although this designation is obsolete. Although the Derbyshire deposits are now largely mined out, other varieties of fluorite are still among the most actively traded and collected mineral samples, as they occur in a wide range of colors and forms. 5. Uses: The majority of the United States annual consumption of fluorspar is for the production of hydrofluoric acid (HF) and aluminum fluoride (AlF3). Metallurgical grade fluorspar contains between 60 and 85% CaF2. Thick widespread carbonate rock units of the Upper Mississippi River Valley once hosted large amounts of fluorite. However, quartz is much harder than fluorite. Fluorite is too soft to be used as jewelry, but the Romans mined a massive crystalline variety of fluorite, later known as Blue John or Derbyshire spar, that exhibited a distinctive color banding of blues, violets and purples. Which Country Uses the Least Alternative Energy? Description 1. The majority of the United States annual consumption of fluorspar is for the production of hydrofluoric acid (HF) and aluminum fluoride (AlF3). Vein mining is commonly done by shrinkage stoping, cut-and-fill, and open stoping where strong walls occur. Fluorite also exhibits the property of thermoluminescence.[31]. The word fluorite is derived from the Latin verb fluere, meaning to flow. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite.[6].
