Fluorspar is a non-metallic mineral of fluorite composed of Calcium and fluorite (CaF2). Metallurgical grade Fluorspar consists of 60-96% CaF2 mainly used in steel production. It is used as a flux to lower the melting temperature and increase the chemical reactivity to help the absorption and removal of sulphur, phosphorus, carbon and other impurities in the slag. In cement industry is used as a flux to speed up calcination process and enable kiln to operate at lower temperatures.
