Fluorspar is the commercial name for the naturally occurring mineral fluorite, composed of calcium and fluorine (CaF2). Fluorspar is the predominant commercial source for the chemical element fluorine. Fluorine is a non-metallic element and the lightest of the halogens and therefore largely irreplaceable in its use.

From 1835 to the early 1870s, little fluorspar was mined. Only small amounts were produced from the early 1870s to about 1890, when an expanded market was created by the development of the basic open-hearth steel furnace in which fluorspar was used for flux. Production since 1890 had been erratic, but in general had risen.
