摘要以硼泥、氧化钙为原料经过消化、碳化过程制备碳酸氢镁溶液,再经过热解过程制备碱式碳酸镁。研究了消化反应时间、氧化钙用量、碳化固液比与碳化压力对硼泥中镁浸出率的影响,分析碳酸氢镁溶液的稳定性,通过XRD确定重镁水的最佳热解温度,利用SEM对产品外貌进行了表征。结果表明,镁的浸出率随着消化时间的延长、氧化钙用量和碳化压力的增加而提高,最佳消化时间为2 h,氧化钙用量为20%,碳化压力为0.2 MPa,碳化固液比为100 g/L。热解温度在70 ℃及以上,产物是4MgCO₃·Mg(OH)₂·4H₂O,热解温度越高产物结晶越完整,同时产物组成越单一。碳酸氢镁溶液在90 ℃下热解90 min,得到的碱式碳酸镁的产率达到95.3%,且产物外貌随热解温度的升高出现由针状向球状转变。

Abstract: Magnesium bicarbonate solution was prepared from boron sludge and calcium oxide through digestion and carbonization.and then basic magnesium carbonate was prepared through pyrolysis. The effects of digestion time, dosage of CaO, carbonation ratio of solid to liquid and carbonation pressure on the leaching rate of magnesium from boron sludge were studied. Stability analysis of magnesium bicarbonate solution. The optimal pyrolysis temperature of heavy magnesium water was determined by XRD and the appearance of the product was characterized by SEM. The results showed that the leaching rate of magnesium increased with the increase of digestion time, calcium oxide dosage and carbonization pressure.The optimal digestion time is 2 h, the dosage of calcium oxide is 20%, the carbonation pressure is 0.2 MPa, and the carbonation solid-liquid ratio is 100 g/L. The pyrolysis temperature was 70 ℃ or above, and the product was 4MgCO₃·Mg(OH)₂·4H2O. The higher the pyrolysis temperature, the more complete the product crystallization and the more simple the product composition. At 90 ℃ for 90 minutes, the efficiency of magnesium bicarbonate solution reached 95.3%, and the appearance of the product changed from needle shape to spherical shape with the increase of pyrolysis temperature.

Key words: boron mud carbonization efficiency of pyrogenation basic magnesium carbonate
