PROBLEM TO BE SOLVED: To provide a recovery method of metals from a recycled raw material of a lithium-ion battery, which can reduce a treatment cost.SOLUTION: The recovery method of metals from a recycled raw material of a lithium-ion battery is a method for recovering object metals from the recycled raw material of a lithium-ion battery containing lithium, manganese, and one or more elements selected from nickel and cobalt. The recovery method comprises: a leaching step where the object metals are leached and at least a portion of manganese is left in the residue by contacting the recycled raw material of a lithium-ion battery only with an acid; a separation step where the residue is separated from a liquid after leaching obtained in the leaching step to obtain a liquid after separation; and a recovery step where the object metals are recovered from the liquid after separation.SELECTED DRAWING: Figure 1
