| titleOfInvention | A kind of compound extracting system and its extracting process for extracting lithium from brine containing lithium |
| abstract | The invention discloses a kind of from brine containing lithium extracts the compound extracting system and its extracting process of lithium.The compound extracting system loads the Fe (III) for having 2.5~10.4g/L, the extractant B of extractant A and 10%-30% including 10%-60%, surplus is diluent, wherein, the extractant A is neutral phosphine extractant and/or amide kind of extractants, the extractant B is acid phosphine extractant, and the percentage is the percent by volume accounted in compound extracting system.Compound extracting system of the invention can effectively extract lithium from brine containing lithium, can be especially that 1.0-1.8 is effectively stripped lithium in pH, avoid reverse-extraction of high acid to the corrosivity of equipment, lithium is easy to get recycling in strip liquor. |
