Title:

ELECTROLYTIC EXTRACTION METHOD OF NON-FERROUS METAL, ANODE USED THEREFOR AND MANUFACTURING METHOD OF THE ANODE

Document Type and Number:

Japanese Patent JP2017206747

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide an electrolytic extraction method of a non-ferrous metal from an electrolyte containing non-ferrous metal sulfate using an anode containing Pb, capable of further reducing anode voltage than conventional methods using a powder rolled sheet obtained by rolling a powder of Pb and metal oxide, the anode used therefor and a manufacturing method of the anode.SOLUTION: In a method for electrolytic extraction method of a non-ferrous metal from an electrolyte containing non-ferrous metal sulfate using an anode containing Pb, a powder rolled sheet, obtained by rolling a mixed powder of a powder of ruthenium oxide containing 50 mol% or more of RuOand having crystalline diameter at a (200) surface of RuOof 40 nm or less and a power of Pb, is used as the anode.SELECTED DRAWING: Figure 4
