Fluorine - Production, Uses, Compounds: Fluorspar is the most important source of fluorine. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. During the distillation calcium sulfate (CaSO4) is formed, which is insoluble in HF. The hydrogen fluoride is obtained in …

Global production of fluorspar in 2018 reached 6m tonnes, of which 9.3% was produced in Mongolia. In 2020, Mongolia produced more than 10% of the world's total production of 7.2m tonnes. Excluding its two neighbors, Mongolia has exported small quantities of fluorspar to South Korea on a trial basis before. Export to China first started in 2002.

Fluorite. Fluorite is commercially named fluorspar composed of calcium fluoride (CaF 2 ). It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and ...

Fluorspar is a neutral flux often used as an additive in steel- making slags to improve fluidity, but it has also been used in combination with lime as a primary slag in electroslag refining (Duckworth and Hoyle, 1969). Fluorspar is available in several grades, with the lowest grade often used for steelmaking. When the
