| titleOfInvention | Manganese-lithium separation method in comprehensive recovery of ternary battery waste |
| abstract | A manganese-lithium separation method in the comprehensive recovery of ternary battery waste relates to a method for recycling battery waste. The method comprises the following steps: a, carrying out acid leaching on waste ternary battery powder to obtain impurity-removed liquid; b. precipitating a cobalt hydroxide and nickel hydroxide mixture by using sodium hydroxide; c. the washing liquid and the filtrate are adjusted with dilute sulphuric acid to adjust the PH value, and cobalt sulfide and nickel sulfide are precipitated; d. regulating the pH of the filtrate and the washing liquid by using sodium hydroxide to precipitate manganese ions to obtain a manganese hydroxide filter cake, a lithium-containing filtrate and a washing liquid; e. evaporating and crystallizing the lithium-containing filtrate and washing liquor to remove sodium sulfate to obtain concentrated lithium solution; f. and precipitating lithium carbonate by using a saturated sodium carbonate solution to obtain a lithium carbonate filter cake and a lithium precipitation mother solution. The invention solves the problem that manganese ions and lithium ions can only be extracted in the prior art, and removes the manganese ions by a hydrolysis method, thereby achieving the purposes of separating manganese from lithium and respectively recovering the manganese ions and the lithium ions without extraction operation, simplifying the preparation process, shortening the process flow, reducing the material consumption and the energy consumption, and saving the production cost by more than 20 percent. |
