| Abstract Scope |
Indium as a so-called hitchhiker metal is extracted almost entirely in course of the primary zinc production. Thus, a strong dependence on the output of the corresponding base metal is given. Taking the annually growth rate of approximately 3 wt-% in the case of zinc production and the one from indium, respectively around 15 wt-% into account, it is obvious that a shortage is faced. Because of the relative new application area of indium in high-tech products a great potential of dumped indium is present in the residues of the past production. Therefore, the present paper describes the characterization and the possible treatment of such a residue, including the thermodynamic background for a pyrometallurgical extraction of indium and silver. |
