Title:

METHOD FOR RECOVERING METAL FROM COMPOSITE METAL OXIDE

Document Type and Number:

Japanese Patent JP2014122369

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a method for recovering metals from a composite metal oxide under conditions of reducing the number of steps and saving energy consumption.SOLUTION: A method for recovering metals from a composite metal oxide includes: a melting step to heat and melt CaX(X is any one of F, Cl, Br, or I); an addition step to add the composite metal oxide to CaXbefore or after the melting step; a reduction step to reduce the composite metal oxide in the molten salt obtained via the melting step and the addition step with metal Ca; and a recovery step to recover metals included in the composite metal oxide.
