Using a salting-out technique with alcohol, precipitation of borax from a stripping solution containing boric acid after the solvent extraction process is investigated. From the low solubility of borax and small temperature effect on the solubility, ethanol was selected as a salting-out agent. The X-ray diffraction results show that the precipitates were borax decahydrate. 74% of boric acid present in the organic phase is recovered as precipitates when the volume ratio of the organic phase to the stripping phase is 2.
