Process Of Inc Metal By Acid Leach

Hydro metallurgical process makes it possible to recover high purity inc directly from EAF dust. One of the main components of inc included in EAF dusts is inc oxide. Thus the mechanism of inc oxide leaching is important to develop the new hydro metallurgical inc recycling process. Leaching test of inc oxide in hydrochloric acid and sulfuric acid solution has been carried out kinetically.

    A process for the recovery of inc metal from a inc mineral includes the steps of leaching the inc mineral in a solution including a halide species formed from two or more different halides to leach the inc into the solution. The inc-bearing solution is then electrolysed to yield inc metal and to generate the halide species.
