Fluorite (CaF2)

Fluorite is in the composition of (CaF2) calcium fluoride, and when pure it contains 51.3% Calcium and 48.7% fluorine. It comes from the Latin word fluere (to flow) because it is used as a slag maker in metallurgy and has a low melting point. It is one of the minerals with the most color variety in nature.

In the commercial field, fluorite can be divided into three classes.

Used in acid industry (Asitspar or Asitgrade)
Used in the chemical industry (Ceramikspar or ceramic grade)
Used in the metallurgical industry (Metspar)
Fluorites with 60-85% CaF2 content, defined as metallurgical grade, are used in steel production to reduce the slag surface pressure, to reduce the melting temperature and slag viscosity, to remove unwanted materials such as Si, S, P and C from iron by passing them into slag, and to prevent wear of refractory bricks. It is used as a binder in the production of abrasives other than the steel industry.
