Metallurgical-spar is used in the manufacturing of aluminium and stainless steel, in extraction of metals such as niobium and tantalum, in metal processing to remove unwanted impurities and in various other applications with the principal applications being:
 

Steel production – used as a flux to lower the melting temperature and increase the chemical reactivity to help the absorption and removal of sulphur, phosphorus, carbon and other impurities in the slag. It is wildly used in steel-making, ferroalloy production and non-ferrous smelting.

Cement – used as a flux to speed up the calcination process and enables the kiln to operate at lower temperatures, which is easy to calcination, sintering time and save energy.

Ceramic - Fluorspar is used to make glazes and surface treatments that produce hard glossy surfaces, opalescent surfaces and a number of other appearances that make consumer glass objects more attractive or more durable.

Used in the glass - Ceramic grade is used in the glass production emulsifying glass, opaque glass and colored glass material, can decrease the glass melting temperature, improved melt, melting speed, which can reduce the fuel consumption rate.
