[Problem] To provide a method for recovering niobium and tantalum, capable of separating and recovering niobium and tantalum dissolved in a non-hydrofluoric acid-based aqueous solution. [Solution] The present invention involves: extracting niobium in an oil phase by adding a predetermined amount of 2-octanol as an extracting agent to a non-hydrofluoric acid-based aqueous solution in which niobium and tantalum are dissolved; and separating the non-hydrofluoric acid-based aqueous solution into the oil phase containing niobium and a water phase containing tantalum.
