Fluorite is mined with the open-pit method using equipment like excavators, loaders, and dump trucks. Mining involves removing the soil and rock above the deposits (the overburden) to expose the deposits, then blasting with explosives to extract the mineral ore. Once extracted, Fluorite is transported to processing facilities for refinements.

They are roughly classified into three categories, i.e., fluorite-type, PbCl 2-type, and tysonite-type. The mineral CaF 2 is named fluorite which is the origin of the fluorite-type structure. The fluorite doped with sodium, e.g., (CaF 2) 0.95 (NaF) 0.05 is a classical fluoride ion conductor in which F − migrates via F − vacancies.
