The origin of the name fluorite comes from the use of fluorite as a flux to lower the melting point in steel and aluminum processing. It was originally referred to as fluorspar by miners. Fluorite is also used as a source of fluorine for hydrofluoric acid and fluorinated water. The element fluorine also gets its name from fluorite.
A quartz-type fluorite ore in western Henan contains 41.58% of CaF 2 and 45.76% of SiO 2. The granularity of the inlay is uneven. Part of the fine-grained fluorite is wrapped by quartz and feldspar, which brings certain difficulties to the upgrading of fluorite. A comparative study of process mineralogy, the flotation reagent system and the ...

Abstract The article presents the case-study of flotation of fluorite ore from Kamarposht mine, Iran. The flotation tests allowed optimization of consumption of chemical reagents. The recommended process conditions enable production of flotation concentrate at fluorite content of 61.4% and fluorite recovery of 85.88%.
The fluorspar concentrate produced from a deposit near Cave-in Rock, III., meets all specifications for high-quality ceramic-grade fluorspar. The Fluorspar Beneficiation Problem Acid grade fluorspar which is in great demand by the chemical and aluminum industries, must contain at least 97.5% CaF2 with not more than 1.5% SiO2 and 0.5% …
The Niederschlag fluorite-barite vein deposit in the Western Erzgebirge, Germany, has been actively mined since 2013. We present the results of a first comprehensive study of the mineralogy, petrography, fluid inclusions, and trace element geochemistry of fluorite related to the Niederschlag deposit. Two different stages of …
It was named in 1797 from the Latin word "fluere", which means "to flow". That was because ground up fluorite was added as a flux to provide better flow in making glass and processing iron ore into iron. The chemical element fluorine was not even discovered until 1886, but as you can see was named after fluorite.
