Applications
Three main commercial grades of fluorspar are distinguished: metallurgical grade (75-82% CaF2), ceramic grade (94-96% CaF2) and acid grade (97% CaF2).
Metallurgical grade fluorspar (metspar) representing almost one third of world production volume is used in the manufacturing of aluminium and stainless steel, in extraction of metals such as niobium and tantalum, in metal processing to remove unwanted impurities and in various other applications.
Ceramic grade fluorspar is used in the fabrication of fiberglass insulation, flint glass, opal glass and enamels. Another prominent use for fluorspar or fluorspar mixtures is as a coating for welding rods and in the production of magnesium and calcium metals.
Acid grade fluorspar (acidspar) is the highest valued and economically most important one (two thirds of world production volume) since it is used as a feedstock for the production of HF, principal base for the production of fluorocarbons and -polymers.
