Chemical Formula:
CaF2
Fluorite or Fluorspar is a
mineral composed of calcium fluoride (CaF2), the principal
fluorine-bearing mineral. It occurs as cubic, isometric crystals
and cleavable masses. When pure, it is colorless and transparent,
or translucent with a glassy luster. Impurities cause color in the
stone, and several varieties exhibit fluorescence. Usually found
either in pure veins or associated with lead, silver, or zinc ores,
it is common in limestone and dolomites.Under CaF***7%, that
fluorite powder usually from refine the tungsten ore tailings ,
fine powder , colour should be grey , offwhite , yellowish
brown.
Applications:
Fluorspar usually in Chemical
industry,Ceramic industry,Fiberglass industry,Welding rod
industry
And steel
industry.
Ceramic grade fluorite (*5–*5%
CaF2) is used in the manufacture of opalescent glass, enamels and
cooking utensils. The highest grade, "acid grade fluorite" (*7% or
more CaF2), accounts for about *5% of fluorite consumption in the
US where it is used to make hydrogen fluoride and hydrofluoric acid by reacting the fluorite
with sulfuric acid.
Internationally, acid-grade
fluorite is also used in the production of AlF3 and cryolite
(Na3AlF6), which are the main fluorine compounds used in aluminium
smelting. Alumina is dissolved in a bath that consists primarily of
molten Na3AlF6, AlF3, and fluorits to allow electrolytic recovery
of aluminium. Fluorine losses are replaced entirely by the addition
of AlF3, the majority of which will react with excess sodium from
the alumina to form Na3AlF6
