| titleOfInvention | Method for extracting boron from magnesium-containing saline lake bittern |
| abstract | The invention discloses a method for extracting boron from magnesium-containing saline lake bittern. The method comprises the following steps of: performing multi-stage counter-current extraction on an extract organic phase and raw material liquid by using magnesium-containing saline lake bittern as the raw material liquid, the aryl-containing1.3-binary fatty alcohol as a boron extracting agent and using mixed solution which consists of the boron extracting agent and diluent as the extract organic phase to prepare an extract phase containing boric acid; and performing multi-stage counter-current reextraction on a stripping agent and the extract phase containing boric acid by using aqueous alkali as the stripping agent to prepare boron-containing water solution. According to the method, the content of the boric acid in the magnesium-containing bittern is reduced to be below 30mg/L, while a borax product can be obtained; the extraction ratio of single-stage boric acid is up to over 90 percent, and the boric acid yield ratio is up to over 95 percent; and the method has the advantages of good boron extraction effect, reduced consumption of solvent, simple processes, easiness for industrialization and application and the like. |
