Electrowinning method using an electrolytic taken for the anode and the anode

摘要

To provide a electrowinning with a sulfuric acid-based electrolyte, lower potential for oxygen generation as compared with the conventional anode, the electrolytic voltage and can reduce the power per unit, and the anode of the various types of metal electrowinning electrolytic and harvesting anode can be utilized as, in the electrowinning method using a sulfuric acid-based electrolyte, lower potential and the electrolysis voltage of the anode, providing an electrolytic extraction method capable of reducing the power per unit of electrowinning . A electrowinning for the anode of the present invention, there is provided an anode for electrowinning using a sulfuric acid-based electrolyte, a catalyst layer containing ruthenium oxide and amorphous tantalum oxide of amorphous conductive substrate are intended to form, and electrowinning process of the present invention is a electrowinning method using a sulfuric acid-based electrolyte solution, is to use the electrowinning anode of the present invention.
