Fluorite mining, which supplies most global fluorine, peaked in 1989 when 5.6 million metric tons of ore were extracted.
Chlorofluorocarbon restrictions lowered this to 3.6 million tons in 1994; production has since been increasing.
Around 4.5 million tons of ore and revenue of US$550 million were generated in 2003; later reports estimated 2011 global fluorochemical sales at $15 billion and predicted 2016–18 production figures of 3.5 to 5.9 million tons, and revenue of at least $20 billion.
Froth flotation separates mined fluorite into two main metallurgical grades of equal proportion: 60–85% pure metspar is almost all used in iron smelting whereas 97%+ pure acidspar is mainly converted to the key industrial intermediate hydrogen fluoride.

At least 17,000 metric tons of fluorine are produced each year.
It costs only $5–8 per kilogram as uranium or sulfur hexafluoride, but many times more as an element because of handling challenges.
Most processes using free fluorine in large amounts employ in situ generation under vertical integration.

The largest application of fluorine gas, consuming up to 7,000 metric tons annually, is in the preparation of UF
₆ for the nuclear fuel cycle.
Fluorine is used to fluorinate uranium tetrafluoride, itself formed from uranium dioxide and hydrofluoric acid.
Fluorine is monoisotopic, so any mass differences between UF
₆ molecules are due to the presence of ²³⁵
U or ²³⁸
U, enabling uranium enrichment via gaseous diffusion or gas centrifuge.
About 6,000 metric tons per year go into producing the inert dielectric SF
₆ for high-voltage transformers and circuit breakers, eliminating the need for hazardous polychlorinated biphenyls associated with oil-filled devices.
Several fluorine compounds are used in electronics: rhenium and tungsten hexafluoride in chemical vapor deposition, tetrafluoromethane in plasma etching and nitrogen trifluoride in cleaning equipment.
Fluorine is also used in the synthesis of organic fluorides, but its reactivity often necessitates conversion first to the gentler ClF
₃, BrF
₃, or IF
₅, which together allow calibrated fluorination.
Fluorinated pharmaceuticals use sulfur tetrafluoride instead.
