Document Type and Number:
WIPO Patent Application WO/2020/203187
Kind Code:
A1
Abstract:
A metal ion recovery device having: an undiluted solution tank that accommodates a metal ion-containing undiluted solution containing a metal ion; a recovery solution tank that accommodates a metal ion recovery solution containing metal ions recovered from the metal ion-containing undiluted solution; a cylindrical metal ion selective permeable membrane that separates the undiluted solution tank and the recovery solution tank and through which metal ions selectively pass; an anode that is electrically connected to a face of the selective permeable membrane on the undiluted solution tank side; and a cathode that is electrically connected to a face of the selective permeable membrane on the recovery solution tank side.
