【摘要】 采用硫酸氢铵溶液浸出低品位菱镁矿提取镁，研究了反应温度、反应时间、NH₄HSO₄质量浓度、NH₄HSO₄过量率、转速和粒度对镁浸出率的影响，并得出了最佳工艺条件：反应温度为95℃,反应时间6 h、NH₄HSO₄质量浓度为25%、NH₄HSO₄过量率30%、转速30 rpm,粒度200目，此条件下镁浸出率96.03%。更多还原

【Abstract】 Ammonium bisulfate solution was used to leach low-grade magnesite to extract magnesium, and the effects of reaction temperature, reaction time, NH₄HSO₄ mass concentration, NH₄HSO₄ excess rate, rotational speed and particle size on magnesium leaching rate were studied, and the best process conditions were obtained: reaction temperature of 95℃, reaction time of 6 h, NH₄HSO₄ mass concentration of 25%, NH₄HSO₄ excess rate of 30%, rotational speed of 30 rpm, particle size of 200 mesh, and the magnesium leaching rate was 96.03% under this condition.更多还原
