To provide a method for recovering tantalum where tantalum can be efficiently separated from waste comprising a trace amount of tantalum, so as to be recovered.

Regarding the method for recovering tantalum where a ferric source is added to a tantalum-containing solution, the tantalum in the solution is coprecipitated together with produced ferric hydroxide precipitates, and the precipitate as tantalum concentrate is subjected to solid-liquid separation, so as to recover tantalum, it is preferable that a mixed salt essentially consisting of NaF and KF and comprising a trace amount of tantalum is water-leached, or the water leach residue is subjected to sulfuric acid leaching, and is mixed with the water leach liquid, a ferric source is added to the leach liquid, and tantalum is selectively coprecipitated together with the ferric hydroxide precipitates, thus the above precipitates as tantalum concentrate is subjected to solid-liquid separation, so as to recover tantalum.
