Abstract

See full text

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.
