摘要
介绍几种回收硼酸母液的方法，并提出以硫酸镁作为回收重点的新工艺，在将其转化为轻质氧化镁的同时，副产含硼酸的硫酸钾和氯化铵。试验结果表明，硫酸镁收率在 ９０％ 以上，副产品硫酸钾收率在 ８５％ 以上。
Some comprehensive utilization methods of the pregnant liquor of boric acid are introduced and a new process for recovering magnesium sulfate as the main is presented. In the mean time, the process coproducts potassium sulfate and ammonium chloride during transfer magnesium sulfate into light burned magnesia. The test results showed the recovery rates of magnesium sulfate is above 95% and the coproducts potassium sulfate is above 85%.
