Fluorspar Classification and Application of Industry
In processing of Iron and steel smelting, using fluorspar can improve the fluidity of molten sulfur and phosphorus removal of harmful impurities. Half of world output of fluorspar to produce hydrofluoric acid, and then develop manufacturing cryolite, used in the aluminium industry, etc. Smelting with fluorspar ore generally requires calcium fluoride content greater than 65%, and the main impurity silica also has certain requirements, have strict limits on sulfur and phosphorus. The content of sulfur and phosphorus shall not be higher than 0.3% and 0.3% respectively
Market circulation of fluorspar categories: fluorspar, fluorspar powder, calcium oxide (fluorspar powder), arts and crafts fluorspar, dry- grinding fluorspar powder, glass ceramic fluorspar powder

(1) Metallurgical industry (for the product granularity of fluorspar ore)
Fluorspar is can reduce the melting point of refractory material, promote the slag flow, make the slag and metal fine separation, desulphurization and dephosphorization during the process of smelting, reinforced metal can be calcined and tensile strength etc. Therefore, it is widely used as flux steel smelting and ferroalloy production, iron craft and smelting non-ferrous metal.
(2) Chemical industry (for the product acid-grade fluorspar powder)
Another important use fluorspar is produce hydrofluoric acid. Hydrofluoric acid is through acid grade fluorspar (fluorspar ore concentrate) react with sulfuric acid in the furnace or jar and produced, anhydrous hydrofluoric acid and hydrofluoric acid water, they are all a colorless liquid, volatile, have the exciting taste of intense and strong corrosion resistance. It is in the production of various organic and inorganic fluoride and fluorine element of key raw materials.

(3) Building materials industry (for the product dry grinding fluorspar powder and optical fluorspar)
Fluorspar is widely used in glass, electrode, such as the building materials industry, its dosage for second place in our country.
In the glass industry, fluorspar as fluxing agent and sunscreen to join, it can promote the raw materials of glass. Colorless and light also known as optical fluorspar, fluorspar transparent crystal because of fluorspar on the optical low, low refractive index and higher characteristic of ultraviolet ray, infrared filter, and be used to make and the quality of the optical element.
In the welding electrode industry, dry- grinding fluorspar powder is as one of the main ingredients of covering materials, its role is largely slagging, in alkaline residue, it can reduce the melting point of slag viscosity and surface tension, increase the fluidity of slag can reduce gas impurities in the weld metal and have certain effect to hydrogen. The requirement of dry- grinding fluorspar powder for special electrode is higher, general requirements CaF2 96% or higher, S 0.03 or less, P 0.02 or less.
