  • Method for manufacturing electrolytic copper
    Patent number: 9932682
    Abstract: Provided is a method for producing electrolytic copper having a low Ag content by successfully suppressing the Ag concentration in an electrolytic solution. The electrolytic copper production method involves a step in which blister copper comprising Ag is used as an anode, and electrolysis is carried out under sulfuric acid acidity while maintaining the anode electric potential at a relatively low electric potential in comparison to the electric potential of the Ag elution.
    Type: Grant
    Filed: September 10, 2013
    Date of Patent: April 3, 2018
    Assignees: PAN PACIFIC COPPER CO., LTD., KYOTO UNIVERSITY
    Inventors: Kimihiro Shimokawa, Kuniaki Murase, Atsushi Kitada, Takahito Kasuno
