    We report a low-cost and effective technique for preparing borax from boron-bearing tailings, which is at a low grade of 9.98% B2O3. Well-crystallized borax is achieved by the removal of impurity, evaporation and concentration through the efficient method of sodium roasting and pressure leaching. The morphology, composition and structure of borax are investigated in this study.
