摘要： It is provided a method of recovery lithium ion, comprising:
adding a residue after leaching lithium from an ore containing spodumene into a solution in which a lithium ion is dissolved; absorbing a lithium ion into the residue by reacting the solution containing the residue at 50-90°C; and recovering a cake containing a lithium from the residue in which the lithium ion has been absorbed by performing solid-liquid separation.
