摘要
A process for extracting boron from brines of natural or industrial salt mines which includes the steps of reacting borates contained in the brine with a solution of hydrochloric acid and forming boric acid, cooling the brine containing boric acid, separating the boric acid from the remainder of the brine to obtain impure boric acid and brine having a low boron content, washing the impure boric acid with distilled or demineralized water to obtain purified boric acid, and drying the purified boric acid. Boric acid crystals thus obtained are washed and recrystallized. The remaining boron in the low boron content brine can be removed by extraction in a paraffin solvent. The boron can then be re- extracted from the solvent and converted to boric acid for isolation and purification as above.
