摘要:
在回收磷尾矿中钙镁资源时,通常先将尾矿进行煅烧,然后利用浸取工艺浸取尾矿中的钙镁,用于后续资源回收。在煅烧过程中需要让磷尾矿中的白云石尽量分解,而氟磷灰石得到保留。研究利用HSC Chemistry软件进行磷尾矿煅烧热力学分析优化煅烧条件,在尾矿煅烧物浸取钙镁过程中,基于响应曲面法,分析铵钙物质的量比(7∶1~11∶1)、液固质量比(7∶1~9∶1)、反应温度(60~80 ℃)、反应时间(50~70 min)的交互作用对钙镁浸出率的影响,对钙镁浸出条件进行优化。结果表明,白云石完全分解为CaO、MgO且氟磷灰石不分解的煅烧温度范围为(900~1 200 ℃)。优化钙镁浸出条件:铵钙比物质的量比为10∶1、液固质量比为8∶1、反应温度为71 ℃、反应时间66 min时获得最佳钙镁的浸出率,分别为92.25%和86.19%。依据优化后的浸出条件,进行多次实验,实验结果为钙浸出率为91.95%、镁浸出率为85.85%。实验结果与优化结果较为接近,证明优化结果较为准确,且通过模拟优化及实验验证,可以看出铵钙比对浸出率的影响较大。
