<P>PROBLEM TO BE SOLVED: To provide a method for electrorefining copper which can suppress the production of suspended solids without damaging safety on an operation, and also, can improve electrolytic efficiency, and a method for producing electrolytic copper. <P>SOLUTION: In the method for electrorefining copper using an anode electrode plate comprising crude copper, arsenic and antimony, electrorefining is performed at a current density of ≥290 A/m<SP POS="POST">2</SP>using the anode electrode plate controlled in such a manner that antimony is comprised by ≥50 ppm, and the mass ratio of arsenic/antimony reaches ≥5.0. <P>COPYRIGHT: (C)2012,JPO&INPIT |
