RESEARCH OF EXTRACTING BORON FROM SALINE BRINE BY COMBINED PROCESS OF ACIDIFICATION-EXTRACTION
Taking the brines from Qinghai Xitai Jinaier salt lakes as raw materials, the research of extracting of boric acid by Combined Process of Acidification-Extraction was studied. The result shows that the optimal pH is 2～3; the optimal ratio of iso-octyl alcohol and aviation kerosene is 1:1, phase ratio (O/A) is 0.5, extraction series is 7.With the combined process ,boron acid concentration of extraction raffinate is 27mg·l-1,boric acid recovery is more than 99％.
