Calcium fluoride. Occurring in nature as the mineral fluorite or fluorspar. Calcium fluoride is the primary source of fluorine and its compounds. Pure calcium fluoride is used as a catalyst in dehydration and dehydrogenation and is used to fluoridate drinking water. (From Merck Index, 11th ed)
Fluorspar is recognised as a strategic mineral by the United States of America and the European Union and is mined for the production of calcium fluoride (CaF 2). Global Markets. Downstream Products. Calcium fluoride is a vital component in several industrial applications, including steel production.

grained synthetic fluorspar, calcium fluoride slurry should be calcinated in rotary kilns at temperatures of 900-1100K. Grain size and compression strength strongly depends on calcination time and temperature. X-ray and thermal analysis indicate that calcium fluoride, apatite and sodium fluoride are basic phases of the synthetic fluorspar.

CALCIUM FLUORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. …
Fluoride can be found in both fresh and sea water, in food (e.g., fish, tea), and in the bones of our bodies. In nature, it is found only in compound forms, such as the ore fluorspar (calcium fluoride) in soil and rock. To form sodium monofluorophosphate, sodium metaphosphate is combined with sodium fluoride.
Fluorspar is the most important source of fluorine. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. During the distillation calcium sulfate (CaSO 4) is formed, which is insoluble in HF.

Basic electrodes contain calcium fluoride (fluorspar – CaF 2) in the coating. The slag reacts as a base, thus leaving low sulphur and oxygen contents in the weld metal. The strength and toughness of the weld are therefore the strongest welds produced by any type of electrode, and the resistance to hot cracking is also higher.

Synthetic fluorspar can be produced from waste calcium fluoride slurry settled on dumpsites located near Cracow centre. Synthetic fluorspar exchanges natural raw material used in the metallurgical industry. To obtain grained synthetic fluorspar, calcium fluoride slurry should be calcinated in rotary kilns at temperatures of 900-1100K.
