Fluorochemicals from fluorspar via a phosphate-enabled
CaF 2 (melting point of ~1420°C) is a white solid that is poorly soluble in water (0.016 g liter −1 at 20°C) and insoluble in organic solvents ().To date, limited chemistry is known for the production of fluorochemicals using CaF 2.Rare examples report its use in the synthesis of LiPF 6, PF 5, POF 3, or Ca(SO 3 F) 2 under extremely harsh …

Nokeng: Mining fluorspar hills
Concentrator plant. Nokeng's concentrator will produce about 180 000t of acid grade fluorspar (97% pure fluorspar) and 30 000t of metallurgical grade fluorspar annually from run-of-mine fluorspar ore production of 630 000t. Open-pit mining and modern plant efficiency is expected to put Nokeng in the bottom cost quartile internationally.

The molten cryolite was both solvent and electrolyte and electrolyzing cryolite itself was not a problem. My guess is that the fluorite just helped lower the melting temperature. Fluorite (from 'to flow') has been used for centuries to help 'liquify' oxide slag, in metallurical processing, so the slag could be more readily scraped aside.
