Fluorite powder

Metallurgical industry

Fluorite can reduce the melting point of refractory materials, promote the flow of slag, make slag and metal well separated, desulphurization and dephosphorization in the smelting process, enhance the calcining and tensile strength of metals and so on. 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]

The chemical industry

Another important use of fluorite is 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. [2]

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 fluxing agent, 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 of coloring and fusing in the process of enamel production. Fluorite is also used in enamel industry and casting stone production. [2]

Other USES

With the improvement of people's living standards, the demand for jewelry and handicrafts is increasing. Fluorite has dense structure, bright color and diversity, and has been paid attention to as the raw material of craft carving
