A method for recovering lithium from waste lithium iron phosphate battery and preparing iron phosphate |
| abstract |
The invention discloses a method for recovering lithium from waste lithium iron phosphate batteries and preparing iron phosphate. The intermediate product is leached with an acid solution, and the leaching solution is crystallized or precipitated to obtain a lithium salt product; (3) the leaching residue is added to the phosphoric acid solution, and high-purity iron powder is added to react to obtain Fe(H 2 PO 4 ) 2 (4) introducing an oxidant into the Fe(H 2 PO 4 ) 2 solution to carry out oxidation reaction to obtain iron phosphate dihydrate slurry; (5) post-processing the iron phosphate dihydrate slurry to obtain iron phosphate product . The invention realizes the recovery of lithium elements in waste and old lithium iron phosphate batteries and the reuse of iron and phosphorus elements at the same time through a complete set of continuous processes, and finally recovers iron phosphate, improves the economic benefit of recycled products, simplifies the recovery process, and Reduced recycling costs and is environmentally friendly. |
