U.S. fluorspar consumption was satisfied by imports and small quantities of byproduct synthetic fluorspar. Domestically, production of hydrofluoric acid (HF) in Louisiana and Texas was by far the leading use for acid-grade fluorspar. Hydrofluoric acid is the primary feedstock for the manufacture of virtually all fluorine-bearing chemicals,

CaF 2 (melting point of ~1420°C) is a white solid that is poorly soluble in water (0.016 g liter −1 at 20°C) and insoluble in organic solvents ().To date, limited chemistry is known for the production of fluorochemicals using CaF 2.Rare examples report its use in the synthesis of LiPF 6, PF 5, POF 3, or Ca(SO 3 F) 2 under extremely harsh conditions (10–12).
of aqueous HF (Edwards, 2017, p. 107–126; U.S. Department of Energy, 2018, 2019). Consumption Apparent consumption of fluorspar was 450,000 t, a 15% increase compared with 390,000 t in 2017 (table 1). Apparent consumption of acid-grade fluorspar increased by 15% to 378,000 t and that of metallurgical-grade fluorspar increased by 10% to 71,300 t.
