HIGH PURITY SYNTHETIC FLUORITE, METHOD OF ITS PRODUCTION AND INSTALLATION FOR IMPLEMENTATION OF METHOD

摘要

The present invention relates to a high purity synthetic fluorite (CaF2). The present invention further relates to a process and an apparatus for preparing said high purity synthetic fluorite (CaF2), classified as acid grade, starting from fluorosilicic acid H2SiF6 (FSA) and calcium carbonate (CaCO3). Finally, the present invention relates to the use of said high purity synthetic fluorite (CaF2) in the industrial production of hydrofluoric acid.
