| Abstract: | Abnormal variation of electrolyte acidity and abnormal behavior of indium on anode during electrorefining were investigated. pH of electrolyte increases in cathode region but decreases in anode region, and electrolyte acidity could be controlled between 2 and 3,by adding sulfuric acid or sodium hydroxide. A protion of indium enters electrolytic solution it the form of indium ion, and a little In disproportionates into sponge indium and deposits as anode slime. Emulsification can be prevented or eliminated by adding sulfuric acid. |
