本发明涉及一种氯化铵法从氟碳铈精矿提取氯化稀土的方法，首先将氟碳铈原精矿磨细，并与NaCO 3 混合，其比例为原矿∶NaCO 3 ＝1∶0.1～0.4，混合均匀后在400℃～800℃焙烧1～6小时，焙砂用热水洗出NaF，洗出NaF的滤渣干燥后与氯化铵混合，于300℃～600℃焙烧1～3小时，再用热水浸取得到氯化稀土溶液，用20％的环烷酸煤油液萃取，再采用盐酸反萃得到氯化稀土产品。

The results show that, the chloride concentrations and diffusion coefficients are both a one-humped function of elevations (can also be the time scale of seawater infiltration), they increase with the increase of elevation until they get to the peak value, and then decrease with the increase of elevation; an evident relationship is being between the surface chloride concentrations and the wave forces acted on the concrete surface, while there is no much difference among the diffusion coefficients; the diffusion coefficients get to bigger as the depth from the concrete surface increase in the influence of the capillary structures evolution and chloride concentration, but this tendency of change was alleviated with the increase of depth.

研究结果表明：氯离子侵蚀混凝土设施的竖向分布规律为氯离子浓度、扩散系数与标高之间同为单峰函数分布，先随高程变大而变大，达到峰值后，随高程变大而减小；氯离子侵蚀混凝土设施的环向分布规律为混凝土构件表面氯离子浓度、氯离子通量与波浪力之间有明显的对应关系，波浪力越大，则表面氯离子浓度和氯离子通量越高，而扩散系数在各方位角差别不明显；由于混凝土长期服役过程中内部毛细孔隙结构演化以及氯离子浓度的影响，氯离子扩散系数随混凝土深度变大而变大，但这种变化趋势随深度逐渐趋缓。
