  • Calcium Fluoride scale

     · The fluorine anion in fluorite holds strongly to its calcium cation. Thus the reaction is slow. Besides, the solubility product of fluorite in water at 25 o C is very low, in the order of 3.5 x 10-11. Released HF is captured by combining with boric acid B(OH) 3, to form F 3 B a gas that complexes swiftly to [BF 4]-in solutions containing F-.

  • Fluorspar

     · Fluorspar is the commercial name for fluorite, a mineral that is calcium fluoride, CaF2. The name, derived from the Latin word fluere (to flow), refers to its low melting point and its early use in metallurgy as a flux. It is the principal industrial source of the element fluorine.

  • mineral processing fluorides

    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.
