    • PROBLEM TO BE SOLVED: To provide an anode for electrowinning that has lower electric potential for oxygen generation compared with a conventional anode, can reduce electrolysis voltage and a basic unit of electric energy, and is available as an anode for electrowinning for various kinds of metal in electrowinning using a sulfuric acid-based electrolyte solution, and an electrowinning method in which electric potential and electrolysis voltage of an anode is low and a basic unit of electric energy of electrowinning can be reduced in electrowinning using a sulfuric acid-based electrolyte solution.SOLUTION: The anode for electrowinning uses a sulfuric acid-based electrolyte solution and is obtained by forming a catalyst layer that includes amorphous ruthenium oxide and amorphous tantalum oxide on a conductive substrate. The electrowinning method uses a sulfuric acid-based electrolyte solution and uses the anode for electrowinning.
    • 要解决的问题:为了提供与常规阳极相比具有较低的氧发生电位的电解沉积阳极,可以降低电解电压和基本的电能单位,并且可以作为用于电解沉积的阳极用于各种 使用硫酸类电解液的电解冶金中的金属种类以及阳极的电位和电解电压低,电解冶金的电能的基本单位可以使用硫酸类电解液进行电解析出的电解提取方法 电解液。 电解沉积用阳极使用硫酸类电解液,通过在导电性基材上形成包含无定形氧化钌和无定形钽氧化物的催化剂层而得到。 电解提取法使用硫酸基电解质溶液,并使用阳极进行电解沉积。 版权所有(C)2013,JPO&INPIT
