ABSTRACT:
The process for recovering boron values and fluorine values from an acidic aqueous feed liquor containing substantial fluoroborate moieties, including contacting the feed liquor with basic material to adjust the pH thereof to above about 7.0 and provide a first clarified liquor containing the fluoroborate moieties, and contacting the first clarified liquor at elevated temperature with sufficient cation reactant selected from Al(OH).sub.3 or Al.sub.2 (SO.sub.4).sub.3 to precipitate substantially all of the fluorine values as an aluminum fluoride compound and provide a second clarified liquor containing the boron values as boric acid.
