3/7/2019· Fluorine in the form of the mineral fluorite was used in the 1500s to aid in ore smelting. Fluorine was suspected to be an element as early as 1810 but wasn''t successfully isolated until 1886. Many chemists trying to isolate the element would be blinded or even killed by the violent reactions that generally accompany fluorine gas.

Fluorine - Periodic table
Fluorspar (which we now know is mainly calcium fluoride) was very useful because it coined with the unwanted parts of metal ores, allowing the pure metal to flow and be collected. The element fluorine had not yet been discovered and the ‘fluor’ in fluorspar came from the Latin word ‘fluere,’ meaning ‘to flow,’ because this is what it allowed metals to do.
