硼酸与硫酸镁分离过程中浮选工艺的研究与应用

Study on flotation process for boric acid and magnesium sulfate separation

在硫酸分解硼镁矿法生产硼酸过程中,会伴生一定当量的母液,母液中的硼酸和硫酸镁的分离通常没有很好的办法来解决。研究了用浮选工艺分离经过浓缩后的硼酸母液中硼酸和硫酸镁,有效地分离出硼酸和硫酸镁,并且完成该工艺工业化生产。

In the process of boric acid mine production through PengMei mine decomposition by sulfuric acid method, the equivalent of mother liquor will be accompanied, the separation of boric acid and magnesium sulfate in the mother liquor usually has not a good way. The separation of boric acid and magnesium sulfate in concentrated mother liquor is studied by the flotation process, which is proved to separate boric acid and magnesium sulfate effectively, and the technology production is also industrialized.
