| titleOfInvention | Valuable metal extractant from waste lithium secondary battery and method for recovering same |
| abstract | [PROBLEMS] To provide an extractant and an extraction method for recovering valuable metals such as cobalt and lithium from a waste lithium secondary battery with a high extraction rate and a high metal purity. SOLUTION: A valuable metal extractant from a waste lithium secondary battery containing a phosphorus-containing compound such as a bis (1,1,3,3-tetramethylbutyl) phosphinic acid derivative as an active ingredient. After adding a mineral acid aqueous solution to the crushed product of the waste lithium secondary battery, the first step of filtering and separating the eluate and the residue, and then the separated eluate contains a metal extractant of a phosphorus-containing compound under pH adjustment. Of valuable metals from waste lithium secondary batteries comprising a second step of contacting with an organic solvent to be subjected to extraction and separation, and a third step of contacting a mineral acid with the organic solvent phase of the extract to perform back extraction and separation. A method is also disclosed. |
