Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain high concentration of ferric ions used in dissolving ore to increase dissolving efficiency by removing unnecessary metal ions as much as possible and oxidizing by iron oxidizing bacteria. SOLUTION: In recovering an objective element from the water solution of the ore by means of solvent extraction, the solvent in the water layer is first removed from the solution by adding thereto one or more of a processing agent selected from the group consisting of sulfur, activated carbon, and other agent. Then iron ions in the water solution from which the solvent is removed are oxidized, and next precipitated by neutralizing the water solution after the oxidizing. The separated precipitate from the water solution is reused for dissolving the ore. COPYRIGHT: (C)2003,JPO
