<p>Disclosed is a method for recovering high-quality tantalum from tantalum-containing waste, with which it is possible to reduce a variety of impurities such as antimony (Sb) and phosphorous (P), which hinder the reuse of tantalum in tantalum capacitors. The method for recovering tantalum from tantalum-containing waste is characterized in that tantalum-containing waste is subjected to acid treatment and then alkali treatment, thereby recovering tantalum. Acid treatment is preferably carried out using acid containing hydrochloric acid, and alkali treatment is preferably carried out by sodium hydroxide or potassium hydroxide. The tantalum-containing waste is preferably a tantalum sintered compact removed from tantalum capacitors.</p>
