Termodynamic analysis of the chloride suspension roasting of the gold-containing magnetic fraction.

Аннотация

The article presents a thermodynamic analysis of various reactions occurring during chloride sublimation roasting of the magnetic fraction. In practice, for the extraction of noble metals from the magnetic fraction, the processes of hydrochlorination and chloride sublimation have been proposed. Based on thermodynamic analysis, it should be noted that iron is much better chlorinated than its oxides FeO and Fe2O3, which once again proves the need for oxidative roasting in order to convert iron into hardly chlorinated oxides.
