* Application
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.
