Fluorspar Extraction Processing Flowsheet
Fluorspar is found generally in veins, in gneiss, slate, limestone, crystalline limestone, and sandstone; often as gangue of metal ores, particularly of lead ores. It is sometimes mixed with barite and celestite; and as these minerals are partly sulphur in composition, they lower the value of fluorspar, as sulphur is injurious to iron and steel.

Fluorite - Wikipedia
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as Fluorite.

niobium processing | History, Ores, Mining, & Extraction ...
The tantalum is extracted as a fluoride in the organic solution, while niobium remains in the aqueous residue, or raffinate. The niobium is then precipitated from solution as a fluoride by the addition of ammonium hydroxide, and the filter cake is dried and roasted, or calcined, at 900–1,000 °C (1,650–1,800 °F) to obtain niobium pentoxide. This oxide may be reduced aluminothermically to produce niobium …
