Advances in the Use of Fluorspar for Fluoridation - JSTOR

fluorspar is hydrofluoric acid. This is used in the preparation of most fluoride salts. This acid is obtained by acidulation of fluorspar with sul-furic acid: CaF2 + H2SO4 -> CaSO4 + 2HF Hydrofluoric acid could be used (and was once used in at least one munici-pal water plant) directly, but it is usu-ally too difficult to handle in water plants.
