The article considers the behavior of iron and lead compounds and their effect on the oxygen content in copper-lead mattes. The substantiation is given for the statement that the consideration of copper-lead matte in the form of a quasi-triple Cu2S PbS FeS system does not seem to be correct. When studying the thermodynamics of copper-lead mattes, it is necessary to take into account the oxygen content and the form of its presence in mattes. Such an approach allows the most comprehensive assessment of the behavior of copper, lead, arsenic and antimony in the process of converting copper-lead mattes. The oxidation mechanism of iron and lead sulfide and their mutual in- fluence on the formation of wustite and magnetite are shown based on the results of thermodynamic analysis. The Gibbs energy of the oxidation reactions of FeS and PbS was calculated. |
