Fluoride Reduction / HF

The removal of fluoride requires that the hydrofluoric acid (HF) be converted to calcium fluoride (CaF2) which is insoluble. Calcium fluoride is a relatively insoluble salt and therefore the low fluoride discharge limit is obtainable because calcium fluoride solubility in water is very low. The calcium fluoride will precipitate and then can be

Fluorochemical industry - Wikipedia

Inorganic fluorides. About 3 kg (6.5 lb) of metspar grade fluorite, added directly to the batch, are used for every metric ton of steel made. The fluoride ions from CaF 2 lower the melt''s temperature and viscosity (make the liquid runnier). The calcium content has a tangential benefit in removing sulfur and phosphorus, but other additives such as lime are still needed.
