8. Electro-refining
Indium cement is used to manufacture anodes for electrorefining. This can be carried out in an aqueous or molten-salt medium. The aim is to obtain indium with a minimum purity of 99.95%.
8.1 In aqueous media
The redox half-reactions for indium are :
at the anode: In 0 → In 3+ + 3rd - ;
at cathode: In 3+ + 3e - → In 0 .
The faster the In 3+ ...
