Review of the Fluorspar Industry

The ore is crushed, washed and screened before processing (Fig. 2). Most modern plants use a combination of gravity and froth flotation processes. Gravity concentration uses liquids to separate the gangue minerals to produce either a coarse grained metallurgical grade fluorspar or to provide the feed for a flotation ...

inorganic chemistry

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.
