Fluorspar Lumps 85%, Nature Fluoride Mine For Steel Industry
Size : 10-70MM
Half of the world fluorite production to produce hydrofluoric acid,
thus developing manufacturing cryolite, used for smelting aluminium
Fluorite is also widely used in glass, ceramics, cement and other
building materials industry
In the glass industry, add fluorite as fluxing agent &
sunscreen, it can promote the glass raw materials melting.
Different glass, added different quantity
In cement production, fluorite as mineralizer to join. Fluorite can
reduce the burden of the sintering temperature, reduce fuel
consumption, but also can enhance the sintering clinker liquid
viscosity, promote the formation of tricalcium silicate.

Chemical Formula: CaF2
Fluorite (also called fluorspar) is a halide mineral composed of
calcium fluoride, CaF2. It is an isometric mineral with a cubic
habit, though octahedral and more complex isometric forms are not
uncommon. Crystal twinning is common and adds complexity to the
The word fluorite is derived from the Latin root fluo, meaning "to
flow" because the mineral is used as a flux in iron smelting to
decrease the viscosity of slags at a given temperature. This
increase in fluidity is the result of the ionic nature of the
mineral. The melting point of pure calcium fluoride is 1676 K.
In 1852 fluorite gave its name to the phenomenon of fluorescence,
which is prominent in fluorites from certain locations, due to
certain impurities in the crystal. Fluorite also gave the name to
its constitutive element fluorine.
Fluorite is a colorful mineral, both in visible and ultraviolet
light, and the stone has ornamental and lapidary uses.
Industrially, fluorite is used as a flux for smelting, and in the
production of certain glasses and enamels. The purest grades of
fluorite are a source of fluoride for hydrofluoric acid
manufacture, which is the intermediate source of most
fluorine-containing fine chemicals. Optically clear transparent
fluorite lenses have low dispersion, so lenses made from it exhibit
less chromatic aberration, making them valuable in microscopes and
telescopes. Fluorite optics are also usable in the far-ultraviolet
range where conventional glasses are too absorbent for use
