Typical 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 onethird of world production volume is used in the manufacturing of aluminium andstainless steel, in extraction of metals such as niobium and tantalum, in metalprocessing to remove unwanted impurities and in various other applications.

Ceramic grade fluorspar is used in the fabrication of fiberglassinsulation, flint glass, opal glass and enamels. Another prominent use forfluorspar or fluorspar mixtures is as a coating for welding rods and in theproduction of magnesium and calcium metals.

Acid grade fluorspar (acidspar) is the highest valued andeconomically most important one (two thirds of world production volume) sinceit is used as a feedstock for the production of HF, principal base for theproduction of fluorocarbons and -polymers.
