(1) Fluorite has the characteristics of reducing the melting point of refractory materials, promoting the flow of slag, separating slag and metal well, desulfurization and dephosphorization in the smelting process, and enhancing the calcining and tensile strength of metals.Therefore, as a flux, it is widely used in iron and steel smelting and ferroalloy production, iron melting process and non-ferrous metal smelting.
(2) Chemical industry
Another important use of fluorite is in the production of hydrofluoric acid.Hydrofluoric acid is produced by the reaction of acid grade fluorite (fluorspar concentrate) with sulfuric acid in the heating furnace or tank. It can be divided into anhydrous hydrofluoric acid and hydrofluoric acid with water. They are all colorless liquid, volatile, with strong stimulating smell and strong corrosive.It is a key raw material for the production of various organic and inorganic fluorides and fluorines.
(3) building materials industry
Fluorite is also widely used in glass, ceramics, cement and other building materials industry, the amount of which occupies the second place in China.
In the glass industry, fluorite as a flux, sunscreen added, it can promote the melting of glass raw materials;Fluorite is added as a mineralizer in cement production.Fluorite can reduce the sintering temperature of the charge, reduce fuel consumption, enhance the liquid viscosity of the clinker during sintering, and promote the formation of tricalcium silicate.In the ceramic industry, fluorite is mainly used for enamels, which can play a role in the production process of enamels.Fluorite is also used in enamel industry and casting stone production
(4) With the improvement of people’s living standards, the demand for jewelry and handicrafts continues to increase.Fluorite has dense structure, bright color and variety, so it has been paid more attention as the raw material of craft carving.
