The present invention relates to an apparatus for collecting useful metal ions from an aqueous solution and a method for collecting useful metal ions using the same, and provides an apparatus for collecting useful metal ions and a method for collecting useful metal ions using the same, the apparatus comprising: an adsorption/desorption reaction tank having at least one ion-collecting column for adsorbing metal ions in a supplied aqueous solution; a washing water storage tank having washing water stored therein, which is supplied to the ion-collecting column onto which the metal ions are adsorbed; and an extracted-solution storage tank having an extracted solution stored therein, which is supplied to the ion-collecting column to elute the adsorbed metal ions. The present invention is environmentally-friendly since the present invention reuses washing water frequently used in a process of adsorbing, desorbing, and collecting metal ions in an aqueous solution without discharging the washing water to the outside, thereby achieving a continual supply of washing water. In addition, the present invention can collect useful metal ions through an integrated process, thereby remarkably reducing energy required for collecting ions.
