The future of fluorspar

According to forecasts, by 2025, China’s fluorspar production will slowly increase to 4.5 million tons. The fluorination industry, which has the largest demand for fluorspar, and the related new energy and new materials industries will all show good development prospects. The demand for fluorspar will increase in the future.

In addition, the steel smelting industry and the electrolytic aluminum industry are also downstream industries that have a large demand for fluorspar, and the demand for fluorspar will remain stable.

With the development of the fluorochemical industry, the world's consumption of fluorspar: the proportion consumed in steel smelting may drop to 35%; the proportion consumed in the fluorine chemical industry may rise to 50%; the proportion of consumption in the glass and cement industry is about 15%.

Fluorspar is the main source of fluorine in the fluorine chemical industry. The fluorine chemical industry is not only inseparable from the development of military industry, but also closely related to emerging industries. Such as: 5G materials, photovoltaics, wind power, etc. The market demand for lithium hexafluorophosphate has further enhanced the value of fluorspar products, and the demand for fluorspar will continue to increase in the future.

Specific application

New energy industry: The halogen elements contained in fluorspar are the main raw materials for extracting fluorine-containing compounds. In the new energy industry, the production of lithium battery materials (lithium hexafluorophosphate), aluminized borohydrofluoric acid electrolyte, etc. are inseparable from fluorspar.

Semiconductor manufacturing gas: The gas used in the semiconductor industry is collectively referred to as electronic gas. In the semiconductor production process, from chip growth to final device packaging, almost every step and every link is inseparable from electronic gas.

Optical industry: Fluorspar is indispensable in the production of high-quality optical components such as optical objective lenses, spectrometer prisms, anti-radiation ultraviolet and infrared windows due to its low refractive index and high filtering of ultraviolet and infrared.

Pharmaceutical industry: In the medical industry, organic fluorides have very important applications. Among the new drugs currently on the market, 15% to 20% are organic fluorine compounds.

Electronics industry: High-grade hydrofluoric acid using fluorspar as a raw material is a strong acid cleaning agent and corrosive agent, which is used in the cleaning and corrosion of integrated circuits (IC) and very large-scale integrated circuit (VLSI) chips.

Metallurgical industry: Fluorspar, as a flux, is widely used in non-ferrous metal smelting. In the iron and steel industry, fluorspar has the function of lowering the melting point of insoluble substances, promoting the flow of slag, and fully separating the slag and metal.

Chemical industry: Fluorspar is the main raw material for the production of sewage hydrofluoric acid, and the basic raw material for fluorine chemicals (Freon, fluoropolymer, fluorine-containing fine chemicals).

Cement industry: The mineralizer for the production of cement clinker, which can lower the sintering temperature, is easy to calcine, has a short sintering time, and saves energy. At the same time, it can enhance the liquid viscosity of the clinker during sintering and promote the formation of tricalcium silicate.

Glass industry: The raw materials for the production of emulsified glass, opaque glass and colored glass can reduce the temperature during glass melting, improve the melt, accelerate the melting, and reduce the rate of fuel consumption.

Ceramic industry: flux and opacifier in the process of manufacturing ceramics and enamel, and it is also one of the indispensable ingredients for preparing glaze. Fluorspar is used as a ceramic ingredient to reduce the firing temperature and melt viscosity, and improve the quality of the embryo body and glaze.

National defense industry: In the national defense industry, fluorine is mainly used for uranium enrichment and purification. Liquid fluorine can be used as an oxidizer for rocket fuel, and it can also be used as a key element of jet propellants for cutting-edge fighters.
