Calcium fluoride

Metallurgical industry

Fluorite can reduce the melting point of refractory materials, promote the flow of slag, make slag and metal separation, desulfurization, dephosphorization in the smelting process, enhance the calcination and tensile strength of metals and so on. Therefore, as a flux, it is widely used in iron and steel smelting and ferroalloy production, ferritization process and non-ferrous metal smelting. [2]

The chemical industry

Another important use of fluorite is the production of hydrofluoric acid. Hydrofluoric acid is produced by acid grade fluorite (fluorite concentrate) with sulfuric acid in the heating furnace or tank reaction, divided into anhydrous hydrofluoric acid and hydrofluoric acid, they are a colorless liquid, volatile, has a strong stimulating smell and strong corrosive. It is a key raw material for the production of various organic and inorganic fluorides and fluorine elements. [2]

Building materials industry

Fluorite is also widely used in glass, ceramics, cement and other building materials industry, its dosage in China accounted for the second.

In the glass industry, fluorite as a flux, shading agent, it can promote the melting of glass materials; Fluorite is added as a mineralizer in cement production. Fluorite can reduce the sintering temperature of charge, reduce fuel consumption, and enhance the liquid viscosity of clinker during sintering, and promote the formation of tricalcium silicate. In the ceramic industry, fluorite is mainly used as glaze, it can play a role in the production of glaze color and melting; Fluorite is also used in the enamel industry and in the production of cast stone.

Other USES

With the improvement of people's living standard, the demand for ornaments and handicrafts is increasing. Fluorite has dense structure, bright color and diversity, as the raw material of craft carving is valued by people
