Fluorspar is an industrial mineral that is composed of calcium fluoride (CaF2), which is made up of 51.1 percent calcium and 48.9 percent fluorine. Fluorspar takes its name from the Latin word "fluo" — which means "flow" — as it lowers the melting point of metal ore and and helps it flow more easily.
