Fluoride ion | F- - PubChem
Fluoride Ion is considered a trace element, fluoride is any combination of elements containing the fluorine atom in the -1 oxidation state (fluoride ion). Due to its reactivity, fluorine is found in nature as fluorine compounds or fluorides. Fluoride inhibits various enzyme systems, erythrocyte glycolysis and binds Ca++, causing anticoagulation and other toxic effects.

Fluorite Ore Mineral Processing Plant
Fluorite ore is brittle and fragile. It is easy to produce many high-grade powdery ores during crushing, and there will be some loss in the process of gravity separation and manual separation. Therefore, the gravity separation and manual separation of fluorite ore tailings are often go to the flotation process to improve the concentrate grades.

Fluorine - Properties - Price - Applications - Production
They are primarily driven by supply, demand and energy prices. In 2019, prices of pure Fluorine were at around 1900 $/kg. Fluorine is obtained by the electrolysis of a solution of potassium hydrogendifluoride in anhydrous hydrofluoric acid. Hydrogen fluoride is produced in kilns by the endothermic reaction of fluorite (CaF2) with sulfuric acid.
