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。There is about 10%and 15%of boric ac id in sodium sulfate by producing boric acid.This paper analyzed the feasibility for separa ting boric acid from sodium sulfate a ccording to the physical data and gra nularity distribution.In experiment,it can separate boric acid from by -producing sodium sulfate and separated boric a cid returns the system of acidolysis or crystal.So it would decrease the p ollutes,increase the recovery of boric acid and get hold of sodium salt.
