| titleOfInvention | A kind of method efficiently extracting lithium from salt lake brine |
| abstract | The present invention relates to and a kind ofly efficiently extract the method carrying lithium from salt lake brine, the method comprises the following steps: (1) first by extraction agent, altogether extraction agent and thinner composition extracted organic phase, again by this extracted organic phase and salt lake brine by volume 3 ~ 4:2 mix and carry out three grades and extract, single extraction time is 2 ~ 10min, obtains organic phase; By step (1) in the organic phase that obtains to mix with back extraction acid solution (0 ~ 1mol/L) and carry out three grades and strip, single back-extraction time is 2 ~ 10min, collects aqueous phase and is the aqueous solution containing lithium ion.The common extraction agent of extraction system of the present invention is hydrophobic nature ionic liquid, compared with traditional synergist iron trichloride, not only avoid the interference that iron ion brings, and greatly reduce reextraction acidity, the more important thing is the separation factor significantly improving lithium magnesium, decrease the elution step of magnesium ion; In addition, present invention process is simple, and be easy to control, operational reliability is high, and organic phase recycling is good, greatly reduces the production cost that salt lake brine carries lithium. |
