| 摘 要： | 在硼酸的生产过程中，副产物硫酸钠中含有10％－15％的硼酸，依据本系统的物性参数及粒度分布情况，从理论分析入手，讨论了采用沉降分离的可行性。通过实验，很好地分离出了硫酸钠中的硼酸，得到的粗硼酸又返回到了酸解工艺或结晶系统，减少了污染，提高了硼的回收率，钠盐又得到了利用。

| Abstract: | Abstract: In the production of boric acid , the boric acid content in by - product sodium sulfate is 10% ~ 15 % . On the basis of parameters of physical properties and granularity distribution of this system , starting from theoretical analysis, the feasibility of adoption of sedimentation separation is discussed . Through experiment, boric acid in sodium sulfate are successfully separated out, the crude boric acid thus obtained is returned back to acid decompasition process or crystallization system , pollution is reduced, boric recovery rate raised and so-dium salt is utilized. |

| Keywords: | Key words: boric acid sodium sulfate sedimentation separation |
