A method for recovering copper according to an embodiment of the present invention comprises: a pressure leaching process of subjecting a raw material containing copper to pressure leaching in a copper spent electrolyte containing copper and sulfuric acid, thereby leaching copper, contained in the raw material, and precipitating iron, contained in the raw material, in the form of iron oxide; and an electrolysis process of electrolyzing a post-pressure leaching process solution, discharged from the pressure leaching process, to electrodeposit and recover copper at a negative electrode, wherein the concentration of sulfuric acid in the post-pressure leaching process solution is 20 g/L to 40 g/L, and the reaction temperature of the pressure leaching process is 150°C to 200°C.
