▎ 摘 要
NOVELTY - Selectively recovering lithium from lithium manganese iron phosphate, comprises reacting lithium manganese iron phosphate powder with sulfuric acid solution for 30-120 minutes, where the concentration of the sulfuric acid solution is 1-3 M, and the weight ratio of the lithium manganese iron phosphate powder to the sulfuric acid solution is greater than 1:3 and less than 7. USE - The method is useful for selectively recovering lithium from lithium manganese iron phosphate.
