A method for preparing lithium carbonate with low fluorine content by recycling lithium iron phosphate battery |
| abstract |
The invention belongs to the technical field of recycling and utilization of waste batteries, and in particular relates to a method for preparing lithium carbonate with low fluorine content by reusing lithium iron phosphate batteries. (2) Purify the leachate, and filter to obtain purified solution and purification slag; (3) Perform precipitation reaction on the purified solution, and filter to obtain iron phosphate and precipitation mother liquor; (4) Perform an open-circuit purification of the precipitation mother liquor, and filter to obtain a Purification liquid and primary hydrolysis residue; (5) Passing the primary purification liquid into a resin with fluorine selective functional groups to obtain a defluorinated purification liquid; (6) Carrying out a secondary purification of the defluorinated purification liquid, and filtering to obtain a secondary purification liquid and secondary hydrolysis residue; (7) the secondary purification liquid is subjected to resin deep impurity removal. The method of the invention can obtain lithium carbonate with low fluorine content, and utilizes the properties of the raw material itself and the interaction between impurities to achieve a remarkable removal effect of fluorine in the whole process. |
