Study on Sodium-Calcining of Boron Concentrate

Abstract:

Boron concentrate obtained from paigeite mineral by magnetic separation was treated by using sodium-calcining method. Mass of NaOH, calcination temperature and time that influence the leaching rate of B2O3 was investigated. Phase compositions and B₂O₃ leaching rate of sodium roasting products were analyzed by X-ray diffraction and chemical analysis. The results showed that the suitable processing parameters were addition of NaOH 10 times by theoretical mass, calcination temperature 600°C, holding time 4h. Under the above conditions, the leaching rate of B₂O₃ reached 92.94% when the leaching temperature, leaching time and liquid-solid ratio is 99°C, 2h and 10:1, respectively.
