Title:
METHOD FOR REMOVING IRON FROM IRON-CONTAINING SOLUTION, AND METHOD FOR RECOVERING VALUABLE METALS
Document Type and Number:
WIPO Patent Application WO/2016/159001
Kind Code:
A1
Abstract:
This method for removing iron from an iron-containing solution removes iron from an iron-containing solution that includes iron ions, wherein in a mixture obtained by adding a lithium ion cell positive electrode material that contains manganese to an acidic solution of sulfuric acid, and obtaining a positive electrode material-containing solution, followed by mixing of the iron-containing solution into the positive electrode material-containing solution, the manganese ions are caused to precipitate as manganese dioxide, and the iron ions included in the iron-containing solution are caused to precipitate as a solid.
